Investigating numbers

22nd Feb 2026

Time for a catch up on P3’s number work. 

At the beginning of term 2 we investigated if we could make a value group for a number within 1 minute. 

There were some fantastic examples of team work, as everyone shared turns and worked in groups to complete this investigation challenge. 

We found that as numbers got bigger, counting in groups of one was not very helpful. 

Time to look at tens and units to help us with our number building!
