Overview
The teacher will begin with a poem that has to do with exchanging coins. The teacher will read the poem “Smart” by Shel Silverstein and model the exchanges of money on the board with magnetic coins. The teacher will talk to the students about how the little boy is not making good trades with his coins.
The students will work in pairs. They will be given a dice with 1 cent, 5 cents, 10 cents, and 25 cents written on the dice. Partner one will roll the dice three times and get those three coins out. They will have to tell partner two how much money that is. Partner two will check and they will switch rolls.
The students will then be given a bag of items that are marked with a price tag. The teacher will ask them in find a certain item. They have to find that item, look to see how much it cost and show the coins needed to buy that item. After doing several of these each student will be asked to pick one item and draw the coins needed to buy that item. One thing that it important to ask the student is “Can you show me another way it show that same amount but with different coins?” The students need to be able to show an amount in more than one way using different coins.
