Our unit study came from Schoolhouse express. I find it helpful to do our bookwork after we do practical learning as it gives the lad a chance to recall his facts.
We did a variety of sheets. A word shape puzzle proved an interesting challenge, but set up a challenge for the criss cross puzzle as he was somewhat stymied by the blocks not having a "word shape" to them. Once he got it through his head that the boxes were different AND he remembered he could play with the xbox upon completion, things went more smoothly. We had a challenge with figuring out different words you can make from the bigger word ladybugs. He came up with lady and bugs, I added bug and lad. And we left it at that.
He thoroughly enjoyed the challenge of the maze and it gave us a chance to talk about the type of insects ladybugs eat.
He did excellent review today and was good at telling me when he didn't remember which gave us a chance to go over that material.
