Lesson 4: Computing Change

In this lesson, students learn to compute the correct change from a $20.00 bill after shopping at the Good Food Store. They will check the prices from the advertisements, which include items like ravioli, soup, apples, bread, and eggs. The exercise reinforces skills in arithmetic and understanding common abbreviations such as "gal" for gallon and "doz" for dozen. The final calculation shows that after spending $11.05, shoppers should receive $8.95 in change, fostering practical math skills for everyday transactions.
