It was girl guide cookie time again over the last month so we've been doing some extra work with "money math".
Ivy used the $4 boxes to practice the 4x tables and did a great job of using subtraction to figure out change. Midway through the selling we reconciled the number of boxes left with the amount of money taken in. It introduced the concept of balancing and we used addition, subtraction, multiplication and money counting to figure it out.
Ella worked on adding 4's to find out how much multiple boxes would cost. She also learned how to write the amounts down and add and subtract it on paper. Today we pulled out a pile of change and made equations with coins. One example was a loonie on one side equals 20 nickels on the other. She counted by 1's, 5's, and 10's. When that project was over she created this wonderful scene with the coins!
