More than you ever wanted to know about 0maths.

Who?

It began as a personal project. I am not a teacher but an engineer. Engineering can be thought of as science-driven design and this approach is very evident in 0maths:

Mostly not multiple choice
If you look at the range of maths sites available, one feature they mostly share is that the answers are multiple choice. You could be forgiven for thinking that the popularity of multiple choice must be because of its educational superiority. This is not the case. Multiple choice dominates simply because programmers want an easy life. In using typed answers we have to be sensitive to the potential range of right answers eg 1/2 , 2/4 , 0.5 may all be correct answers. Algebraic answers create a whole new realm of complexity. It's not easy, but it's worth it:
Typed (or written) answers are about formulating the correct answer, and this may be a different thought process to recognising a correct answer.
Multiple choice questions are one tool in the learning tool kit and we do use them for some questions. However, curious things happen with multiple choice answers and we aim to capture these effects beneficially, rather than have them battering learners haphazardly.
- Multiple choice questions can be hacked. It may not be necessary to calculate the correct answer if there's another way to it. For example if the question is 245842 - 239723, and the options are are 5946, 5872 and 6119, a bright student will see the question as odd - even = odd and will be able to tell you that the answer is 6119 without doing any calculation at all.
- Multiple choice platforms that allow multiple attempts may involve simply clicking at random. No learning happens this way.
- Neural pathways are reinforced on clicked answers. It does not matter if they are right, the answer that is clicked will be remembered.
- If the options are consistent, they will be absorbed a little and associated with the question.
  The great challenge of multiple choice questions is making all answers sound convincing which means the options presented end up being fairly consistent. Let's say we have the question:
  8 x 7 =?
  and the answers presented are:
  52, 54, 56, 58
  All answers will be remembered associated with the 8 (and 7) times table, particularly if the same answers are presented each time.
  0maths uses this side effect positively. For instance, if all the answers presented are in the table being learned, that can help with tables learning. We take this a step further. Consider this question:
  2 x 7 = ?
  with these answers:
  2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24
  Children spot that they can just count from the left and click on the 7th given answer. They will be pleased with themselves because they got it right and got one over on The Man.
  But what just happened? They just got a little more familiar with the numbers in the 2 x table. Because the question was arranged to be hackable, they got it right and the memory (as opposed to the calculation, which they did not do) of 2x7=14 has been reinforced.
  For the next question, they may use an earlier question as a starting point (ie if the question is 8x2, they may count 1 from 14); this will reinforce the earlier question.
Besides, typed answers allow our unique:
Never wrong, only not yet right
0maths' unique never wrong, only not yet right approach was developed for my own youngest daughter who suffered from maths anxiety. She was so scared of getting any answer wrong that she could no longer think.
Apart from its relevance to maths anxiety, this approach has deep implications for all learning:
- We don't actually learn by our mistakes, we learn by getting things right.
- Getting an answer wrong is unhelpful - sometimes children have learned it wrong and they just accept "I'm a ⁷/₁₀ kind of guy". The not-yet-right approach means they will have to get it right to move on, giving them the opportunity to override first learning.
Brain chemistry
Most maths apps have an undue emphasis on speed - whether it be competing against another player or some sort of ticking bomb. From an educational standpoint, quick calculation is an indicator that the result is coming (at least in part) from long term memory but pressure to work fast does not help store memories. In fact, competition produces adrenaline - the fight or flight chemical. Adrenaline increases heart rate, diverts energy to motor muscles and actually shuts down logical thought. Instead, with a stream of only right answers and a reward for each one, 0maths targets dopamine (the "Eureka! I'm so good at this!" brain chemical). Dopamine has been shown to increase attention spans and increase fact retention.
Previous answers accessible
This gives students a sense of progress - "look how many questions I've done." Seeing each individual question on the screen with a right answer is confidence boosting. The other effect of this is that they can scroll up the page to review previous answers, and scroll back down to 'cheat' by entering the answer, if its relevant to the current question. They will have to memorise this and will do this in a way that's helpful to them, such as saying it out loud a few times. This process is helpful to learning as long term memory is key to a lot of maths (times tables & number bonds, being obvious examples).

What?

0maths is a bottomless pit of rapid fire, randomly generated practice questions across nearly 500 topics including addition, subtraction, division, multiplication, percentages, units, fractions, factors, time, money, units, geometry, area and algebra.

It is suitable for all pupils but was particularly designed to embrace the needs of nervous learners with the following innovations:

Adaptive learning. Questions which have not been answered optimally (wrong or slow answers, or 'show me' requested) are remembered, to be emphasised later in a pupil's learning journey.
No 'submit' button. Answers are accepted as soon as they are correct.
No wrong answers, only not-yet-right answers. Mistakes can be undone; answers can be checked and corrected rather than marked as irredeemably wrong. This puts the learner firmly in control.
Hints are given in some cases (i.e digits transposed, units missing, read the question more carefully, etc)
'Show me'. Learners can see the worked solution to almost any question.
No visible timer. People learn best when they are relaxed, so there is no visible ticking clock, though times taken for each question are recorded, and questions answered within an appropriate timeframe earn a reward (virtual coins and topic wedges).
Easier / harder. Most questions (at the teacher's discretion) have easier / harder options. A child can, without shame, ask for an easier question and build up to the harder questions. This may involve easier (i.e. generally lower) numbers, or simpler technique, or the use of visual aids. In the same way, students can make a question harder. When children complain that maths is boring, what they really mean is that it's too easy or too difficult.
First know . Either on request, or after repeatedly asking for help on a question, pupils are given prerequisite topics. An example of this would be if a child is unable to do questions in the 6 times table, they would then be directed to counting in 6's, or adding and subtracting within the 6 times table.
Follow on Just as there are topics that need to be known in advance, there are topics which naturally follow certain question types. In the example of multiplication tables, a natural follow on would be areas of rectangles.
The maths is the game. 0maths is engaging with features such as levels, streaks and rewards and does not rely on irrelevent games as sweeteners. A maths question at the right level is innately satisfying and produces dopamine - one of the brain's reward chemicals. Getting the brain engaged to the right way of thinking takes a little time and a few questions. Irrelevant games break the pattern of concentration and exacerbate ADD.

Where?

We're based in beautiful Aberdeenshire, Scotland.

0maths.com is hosted in the UK and all data is controlled from the UK.

When?

0maths began slowly in 2013 or thereabouts, aimed at the needs of my own children.

In lockdown 2020, it changed gear. Like many schools, our own was struggling with the cycle of work being given, pupils printing the work, work getting back to teachers, getting marked, and feedback returned to pupils. The school pointed us to the many online resources but two out of three of my children found them stressful - wrong answers and visibly ticking timers increased anxiety and reduced learning. The third child got frustrated at having to play a pretty basic game between questions - a game that took longer than the questions. ("Can't I just do the questions?")

Since then I’ve been adding more to it. It’s been like climbing a mountain - every time the summit appears, it turns out not to be the summit. It’s now up to nearly 500 question types.

0maths has been designed to span the digital divide and be universally accessible. It should work fine on anything from a brand new laptop to a ten year old phone. Once it has loaded, it can be used without an internet connection.

Why?

School level maths is not about genius, it's about practice. Some kids need more practice than others, but more children are able to ace their maths than currently do.

Maths is important. It’s the language of the universe. It speaks truth to power. It teaches objective thinking. It makes complex problems easy.

We tend to take maths for granted because it was there right through our childhood, and once we know it, it's just so simple. Really though, maths is a series of spectacular, mind bending inventions which can be reproduced with a pencil and paper.

The very idea of counting is not inate. We (along with some other animals) can observe numbers to 4; beyond that we had to invent the means to record them. Many remote cultures use the number system "1", "2" and "many". The Romans invented the means for recording all numbers they had use for, but it was difficult to work with. The Indians did it better, perhaps magically, with the place-value system (though we credit the arabs for it). Try long multiplication with roman numerals, I dare you.

Other leaps forward came centuries later: zero, negative numbers, the decimal point... etc, and that's just the numbers. Without algebra, calculus, trigonometry, statistics, how much of the universe could we master?

So, there you have it: maths is awesome, and everyone should be given whatever they need to understand it.

Why 0maths?

Yeah, the name's misleading - kids may suppose they are going to get to do no maths at all.

It's called 0 maths because zero is a brilliant invention that made maths forever easier. I'd not be so bold as to rate my humble maths site as important as the invention of zero, but it really does make maths easier.

Personal information

The site can be used without supplying any personal information at all. However, if you log on, we (Influenca Ltd) record the following:

For pupils:

The name of their school.
The name of their teacher.
Their year group
The (teacher assigned) name of their maths group
Their name as a means of identifying them to their teacher. At the teacher's discretion, this may be be their full name, one name only, or a nickname.
A record of their work for each assignment set by their teacher.
Additionally a username and password will be set for each pupil.

For teachers:

The name of their school.
Their name as they wish to be known to pupils.
Their email address as a means to reset passwords.
Additionally, a username and password is set.

It is only possible to register as a pupil if linked to a teacher or a parent. There is no means of a pupil registering with their email address.

Sensitive Data

We do not hold children's email addresses.
In certain cases the name of the school a child is at may be considered sensitive data. It is suggested that in these cases the child's full name is not used.
Other than the above, data held is not sensitive - the only action a third party could take if logging on as a child would be to do that child's work for them. Consequently, there are no password rules for pupils - they can even be blank, though if their password is blank we do remind that pupil to set a password at each log on.
The likeliest source of an attack on a teacher's account would be a prank attack from within the class. For this reason the priority is that the password is memorable enough to not need writing down, and so the only password rule for teachers is that the password be at least 8 characters long.

Security

We take relevant security precautions, including the following:

The site is secured by https encryption and is only accessible securely.
Inputs received by the server is scrubbed to avoid a SQL injection attack.
Appropriate measures are in place to avoid a cross site scripting attack.

We do our best to keep private information private, and expect you not to share passwords. For practical purposes, to keep things flexible in the classroom, teachers have the facility to view and / or change passwords for their students. Additionally, teachers who are administrators have the facility to reset (but not view) other teacher's passwords within their school. This is to provide a safeguard against data loss in the event of a teacher leaving the school.

Cookies and Local Storage

Unless a language other than English is selected in the settings, we don’t allow any third party cookies at all. If this should change we will notify you.
If a language other than English is selected in the settings, Google will have the facility to set tracking cookies.
If you are logged on:

We store an ID on your device so that we can securely identify who has logged on.

A pupil's 0maths activities may be monitored by staff members at their child's school, including, but not necessarily limited to, their teacher.
We don’t share any specific data with 3rd parties outside of a child's school, other than with people registered as a child's parents or guardians.
We may use a pupil's performance data in an aggregate or anonymous way, such as to draw conclusions about how pupils progress on 0maths, and we may share such conclusions with 3rd parties.

Regardless of whether or not you are logged on:

We set one non-essential cookie:

To allow us to record how users of the site progress over time, we record a random id (named 'rid') against which we record the time taken to answer each question, whether help was needed, the number of mistakes made, the difficulty level, and the question itself. The purpose is to be able to correlate strengths and weaknesses for future visitors so that we are better able to suggest appropriate questions to children, and to give you feedback on how times taken compare with others in general. This ID is not linked to any log on IDs and is independent of, say, homework submissions. This ID is confined to our site -we do not share it with others.

We use several additional non-essential local storage (ie cookie like) elements on your machine to record:

Nationality (for syllabus, currency etc)
School year (for syllabus)
Wedges won (i.e. tasks mastered)
Weaknesses (i.e. to suggest question types)
Current week no (if using week by week)
Current streak
The time stamp of a visitor's last visit and the number of days in succession they have visited 0maths in order to appropriately increment a current 'streak'.
If a child has earned a place on a leaderboard, we also store their initials to save them typing them next time.

We use two essential local storage elements.

The tasks selected
Supplementary data for those tasks (ie chosen times tables, limits for addition).

As the site is aimed at children, it may be wisest to not have them read the privacy policy before using the site. Consequently, essential cookies (ie both of the essential local storage elements and the logon ID cookie) are set even if you click 'not ok' to cookies. Without them the site won't work. In this case the non-essential cookie and all the non-essential local storage elements are not set, other than to record this preference.

Publicly displayed information

If (and only if) a user answers a question such that they warrant a place on a leader board, we invite them to supply a maximum of three initials. These are stored both on our public leaderboard and on their machine by local storage, to save them typing next time.
If a user is logged in at the time they get a place on a leaderboard, we also record their teacher's name, and their school's name on the public leaderboard.
Leaderboards (i.e. a pupil's initials, and in the circumstances described above, their teacher's name and school's names) are displayed to other students who have earned a place on that leaderboard.
Students have the option to decline their place on the leaderboard - in which case their time will be shown against the name anon, and neither teacher nor school are recorded.

Hosting location

We host 0maths.com in the UK, with hostinguk.net.

Communications

We do not record any means of contacting anyone who registers as a pupil. As such, we will never contact pupils.

If you register as a teacher, we will only use your email address for matters connected to your account, such as password resets and notifications about changes to 0Maths.com that may significantly impact your use of the site. We'll send you as many of the former as you need, and no more than 12 of the latter per year.

Contact through the contact form can be totally anonymous. We do not record user ID's with contact messages. The email address field is optional (and is indicated as such). This is to enable children to report errors without being open to communication from an adult.
