Robin made this fun tool that makes different patterns for the different numbers. Above is the 3's. He sanded the wood and pounded the nails all on his own. I wrote the numbers.
We are working on 2's, 3's and 4's right now. We discovered that the threes can be sung to Frere Jacques. Memorizing the times tables is tedious work though, no matter what you do. They just have to be memorized. Even when the concepts are understood, it really just comes down to memorization. So, we try to make it as fun as we can!
