I actually made this a while ago for my daughter but never included photos on the blog. As I have recently received a number of comments about the maths goodies that the kids use and some have asked for more of the home-made items I thought I would include this one.
This is very simple, no frills at all, so as not to distract my daughter.
I started off with a piece of A4 card, folded it in half and then divided the length into a number of smaller sections so that I would know where to cut. (In the photo below I only cut up to the vertical line.)
In the middle I wrote the numbers and then I folded over all the flaps and wrote the answers under each flap.
Yes very simple and no frills at all but when my daughter started doubling and halving numbers it was a great reminder for her.
