discuss it
Cover common errors and misconceptions and allow children to discuss the validity of statements from other fi ctional children, decide which are correct and explain their thinking. You might ask them to consider what resources, models, or images they might use to help the ‘imaginary’ children who were incorrect to develop their understanding even further.

I think this number is 10 because I added 3 + 2 + 5 = 10
20 + 10 = 30 9 + 7 = 16 30 + 16 = 46
The value of the digits are 3, 2 and 5.
The value of the digits depends on where they are placed in the number. The 3 stands for 300, the 2 stands for 20 and the 5 is in the units column so it is worth 5.
