In this lesson children examine pennies and dimes and model subtraction as they listen to a children’s book. They model amounts to 60 cents with coins. They use coin rubbings of pennies and dimes and make a chart comparing the two coins. At the conclusion of the lesson, they begin a word wall and make an entry in their portfolios.
