Spectacular Subtraction in Year One!

 Year One students completed a carousel of activities to recap all of the subtraction methods they have learnt in this unit (PPW models, number lines, rekenreks, ten frames, crossing out, etc.). We discussed how the biggest number always starts a subtraction calculation. As an extension, students were asked to take a number sentence and make a fact family for it!

"I know that subtracting means to take some away" - Ivy

"When I use a ten frame, I make the bigger number first. Then, I subtract the smaller number to get my answer" - Benjamin

"When you have a subtraction question, your answer is always going to be smaller than your biggest number" - Eva

"The biggest number always comes first in a subtraction problem" - Kiara

Spectacular work, Year One!
