This collection of resources supports the teaching of Number and Place Value in primary mathematics. These activities are linked to the year groups containing the corresponding content in the National Curriculum.

Here are some favourite activities selected by the NRICH team.

• Two Dice (Y1) Find all the numbers that can be made by adding the dots on two dice.
• Strike it Out (Y2) Use your addition and subtraction skills, combined with some strategic thinking, to beat your partner at this game.
• Sealed Solution (Y4) Ten cards are put into five envelopes so that there are two cards in each envelope. The sum of the numbers inside it is written on each envelope. What numbers could be inside the envelopes?
• Can you go through this maze so that the numbers you pass add to exactly 100?

These are just a few of the activities on Addition and Subtraction that you can find on the NRICH curriculum pages.

The activities below, taken from the STEM Learning website, complement the NRICH activities above.

### Starting Number Skills
