I just pulled them out this morning and sat down with them - the kids sat right down with me and we worked through all of the wrap-ups. We only have the addition wrap-ups, so it was a good review for my daughter, and this kind of stuff is just what my Kindergarten son is craving right now! It is so simple - you just start your string at a certain number on the left hand side of the plastic card, then (let's say your on the +5 card) you add 5 to that number and wrap around to the answer on the right side. You do this for about 10 different numbers. I asked them why they liked these wrap-ups and this is what they said:
Miss B: "I like them because they are kind of like weaving." (she is my quiet knitter, sewer, etc...)
As I sat down to blog about these, I checked my email and saw an interesting article about making math fun (how providential is that?). Check it out here.
