Most of the booklets inside the lapbook are from the Division Lapbook-- for free at HomeschoolShare
The envelope-looking thing on the right middle is a multiplication chart. I made it using a double four corner fold (sounds harder than it was). You can fold it outwards if you need help with the math facts.
This is the cover of the lapbook. I have tried and tried to find where I got this cut and paste house model. But no go. I learned from this to keep track of the links I followed! Meanwhile, if you know where it's from, please tell me so I can give credit. It made a really cute lapbook cover.
