Little Juan and Juanita decide to sell some items at a school jumble sale. They want to sell everything for 7p. El Nombre explains how, with the help of addition, a mixture of coins can be used to make 7p, which does not exist as a single coin.
Students could explore and display other coin combinations to make 7p and make rubbings on a tree outline to make a money tree. They could repeat this for other amounts and use the money trees to make a display of coin combinations.
