This week in Year 2 we have been learning all about the number line up to 100. The children practised estimating where numbers belong and explained their thinking clearly.
We drew 100cm number lines and carefully added the numbers from 0 to 100. Using what we know about halfway, we placed important numbers such as 50, 25 and 90.
Here are some of the things the children said:
George – “I know 50 goes in the middle because it is halfway between 0 and 100.”
Austin – “25 is halfway between 0 and 50, so I put it at the quarter mark.”
Luna – “I put 90 near the end because it is close to 100.”
Gracie – “I checked my number by thinking about counting in tens along the line.”
