Regrouping 100s & 10s to Subtract | Grade 2
Special | 3m 8s
Regrouping is changing one unit to another unit.
You may hear your child and her teacher talk about Place Value Disks. When learning place value, addition, and subtraction, place value disks are a great tool to tie together your child’s understanding before using the standard algorithm. They are especially helpful when regrouping, that is, changing one unit to another unit.
