The children were consolidating their understanding of column subtraction this week by using place value counters and dienes blocks to support them. They were able to apply the column method
effectively and discuss exactly when it was necessary to regroup and why.
"You can't always subract if you just look at one column so you have to regroup the numbers!" Adam, Hazel class.
"Using the dienes blocks really helped me understand how to regroup." Ethan, Sequoia.
Great job, Year 3!
