Dragon has been working with patterns for several days, now. The first day, we did a worksheet, and it was tough. Especially the ones where he was supposed to leave a blank spot. He needed a lot of help to figure out what was supposed to be happening. So we've been practicing.
So we've spent several days doing patterns of various sorts. Yesterday, we made rod shapes, which looked cool, but I forgot to take a picture. Today, he was already playing with the Duplos, so we used those to practice patterns.
It's still challenging, but with practice, he's making good progress.
