Welcome to the January edition of NRICH, the maths enrichment site .
This site supports teachers and learners of mathematics with thousands of free resources which are designed to develop subject content knowledge and problem-solving and thinking skills. This month the mathematical problem-solving and mathematical thinking theme is Negative Numbers.

As well as a look at what it was to be a pupil in a Victorian classroom , this month's site includes two other articles giving historic contexts to Negative numbers. One was written with pupils in mind and the other designed for teachers and learners alike . A third article gives a useful insight into adding and subtracting negative numbers so, if you have struggled with a model for these operations that works for you, why not look here .

An interactive game based on negative numbers, called Connect Three is also published for the first time this month which is ideal for developing confidence with adding and subtracting positive and negative numbers.

Go to Stage 1 & 2 if you are interested in mathematics at a level usually encountered at primary school.
Go to Stage 2 & 3 if you are interested in mathematics at a level usually encountered at lower secondary school.
Go to Stage 3 & 4 if you are interested in mathematics at a level usually encountered at upper secondary school.
Go to Stage 4 & 5 if you are interested in mathematics usually encountered at post-16 level.
