Once reading and writing were over we moved onto math. Today I read a story called A Dollar, A Penny, How Much and How Many? We talked about money and how to identify it. This was a review for Ian but more of a real lesson for Alec and Evan. The older boys then followed up with a lesson in McRuffy about adding coins. Alec did amazingly well once he learned to distinguish the coins from one another; he had no problem adding the coins in his head.
We did a quick science experiment/ demonstration. Using pennies, vinegar and paper towels we set up an experiment that I know will turn the pennies green by tomorrow morning. I found this idea in one of the science books I have but you can find a similar experiment here. The boys don't know what will happen but I had them make some predictions. Ian thinks that the paper towel soaked in vinegar is going to turn colors from the copper of the pennies wearing off them, which is what Alec thinks too (though they both explained it a totally different way). Evan thought the pennies might get bright, shiny, and clean. Alec thought the pennies might wear away at the bottom but not at the top. Within an hour we could start to see a bit of green showing up and they were getting very excited.
