I used newspaper ads the to have students practice multiplying decimals.
Their instructions were to find at least 5 items from the ad to purchase. They had to purchase more than 2 of each item. Then use multiplication to find out their total cost.
For the next time I do this project, I will give students an amount of item to buy. For example, I will ask them to purchase 4 of one item, 15 of another item and so on. So they get practice multiplying with a variety of numbers.
