Math on the Brain
Wednesday, January 13th, 2010We went home early on Wednesday, due to a local water main break near Teaticket. However, I still kept thinking about what the math lesson would have been that afternoon. We have been working on double digit subtraction lately. I think one of the best ways to practice this is with “virtual blocks” on the National Library of Virtual Manipulatives’ site. Click on “Base Blocks Subtraction” and give it a try!
