Subtracting with Regrouping
Subtracting with regrouping used to be the biggest headache in my primary years instruction. Now, I know it was because I wasn't teaching it conceptually the way I should and could. Since then, and with the help of my Singapore Math colleagues, I've learned a strategy that's the bee's knees. Just adding in the subtrahand as place value cards makes all the difference in the world! If you'd like to see the PowerPoint I put together to explain the teaching process, please visit www.nwmteducationalcoop.org > teacher resources > math support > PowerPoint_SubtractionwithRegrouping and see if this style of instruction might help YOU and more important YOUR STUDENTS! Good luck!
