Place Value on the Playground

The good weather this week led us outside on to the playground to complete our work on comparing and ordering numbers.

 We used large sticks as empty number lines and had to imagine that one end was 0 and the other was 10. Where would 7 be?  Some of the children thought it would be a good idea to find the half way point, which was 5, and this would help us to work out where 7 would be.  

 We had a few goes at finding numbers to 10 and then changed our number lines so that 0 was on one end and 100 was on the other. What would the half way number be now? 

 We practised finding 2 digit numbers on the empty number lines.

 Some children decided to mark out every multiple of 10 to help them find other numbers on the number line.

 The children decided to use another stick to point to the place where they thought the 2 digit numbers would be.  Others used their fingers to count out spaces between the tens numbers.

Good work Robins, you thought carefully about where the numbers would be on the empty number lines.
