This packet contains pages to teach your students WHY and then HOW you regroup when adding and subtracting. A better understanding of the process helps students master addition and subtraction! This can be used alone or as a companion to the Why Before How Singapore Math book. You do not have to have manipulatives to use these pages to teach addition and subtraction but you can use place value disks and/or place value rods and cubes.

*Number Bonds - Addition
*Making Friendly Numbers
