3 digit numbers

Back to place value again... we've been ordering, comparing, and finding numbers on number lines.

We've also been adding and subtracting 100s, 10s and 1s. 

If you practise this at home, I've been encouraging the children to follow these steps to help them...

1) write H T U above the 3 digit number

2) work out which digit is changing, H T or U

3) write down those that stay the same in the correct place

4) add or subtract 

E.g.

We played games where I hid various parts of sums, and the children had to work out what was missing. They responded really well to this challenge and were keen to do more, so you might want to give it a go at home.

CHALLENGE!
