Subject: Teaching subtraction with regrouping
I am doing my teaching internship in a second grade classroom. I have recently introduced subtracting with grouping. The students are having a really hard time with it. I have tried using ones cubes with tens rods, telling the kids that if you flip the problem over and add it adds up like 35-27=8, the 8+7=15 ect... The students understand when I have them walk me through the lesson, but when I let them loose, they seem to forget everything we have been talking about. Thanks for your help!!!
