Today, we are estimating and checking column subtraction.
It's been a while since we did subtraction so remember to line up your calculations carefully and ALWAYS start with the ones column.
First, work through the powerpoint.
Then choose some questions from the activities below.
You do not need to do all of them, choose which section is the right level of challenge for you.
Remember, you don't have to print these activities, it's fine to record your work in a book or on paper.
Choose your challenge!
Are you ready for an extra challenge?
As you complete this challenge, explain your reasoning to someone at home.
