Yesterday we went to Old Navy to go clothes shopping for the kids. It was 40% off if we used our Banana Republic card. So we had a discussion about percentages and a brief tutorial on how to calculate them.
In order to figure out how much we were spending we also practiced rounding up.
Later in the day Zayde brought Adin to Bicycle village to check out the bike that Adin has been saving for. He called me from the store to find out how much was in his bank account and did some mental math to calculate how much more he would need to save in order to get the bike.
We then talked about the fact that he would also have to pay sales tax. So we calculated that - and he negotiated with Zayde to get him to pay for the sales tax.
This afternoon Adin was able to take his money from Chanukah and birthday savings and working as mother's helper for Mitten and buy his dream bike! I'm so happy for him.
