Tigger happy at work.
He worked on adding with nines. He converted it to 10+ as we learned in Math U See.
Then we worked on doing the same process with the eights.
Here is Pooh working hard on his complex addition and subtraction problems.
You can see he's working thru carrying. He actually hadn't done this in a while and did extremely well. I couldn't believe I didn't hear fits and screaming about the problems. Was it the change in environment/place/time? One never knows. Just go with the flow. It's easier. ;D
I noticed some issues with the reading of the larger numbers, such as hundred thousand, million. So I drew houses that gradually increased in size. They started at units and moved up to about 10 millions I think. A sidewalk/driveway is the perfect place to draw that out.
You don't have to get obsessive over neatness. My houses weren't perfect squares but they got the point across.
If you have more ideas that would work with this activity, please post a comment and share!
