Second grade Resource Room math students are hard at work doing addition and subtraction with very large numbers. We are continuing our exploration of "Fairy Tale Math". Our latest story involved figuring out exactly how much candy was on the house that Hansel and Gretel found in the woods. Adding all those jelly beans, chocolate, gum drops and peppermints meant numbers in the thousands and the need for regrouping. Then we discovered that Hansel and Gretel ate some of the candy and we needed to subtract! That required more regrouping. The children used place value cubes, rods and flats to help them with all of this. They could immediately see the need to regroup as they solved these delicious problems.
