Explain how you figured out the answer. Special needs students may need help counting out money. Graphing the coins so they can readily see how many of each coin they have and the value is helpful. It is easier to look on a chart and find 50 cents and then the 2 cents to equal 52 cents. Charts can be used to see what combinations make up a given amount.
Students can match their money to that on the chart.
Accelerated students can help set up the yard sale, become money buddies for the special needs students, and help run the yard sale acting as the cashiers. They add the prices of the items, determine the amount of money needed, collect the money, and make change.
