Video Solutions to help Grade 6 students learn how to use estimation and place value to determine the placement of the decimal point in products and to determine that the size of the product is relative to each factor.
You will not only solve each problem, but your groups will also need to prove to the class that the decimal in the product is located in the correct place. As a group, you will be expected to present your informal proof to the class.
1. Calculate the product. 34.62 x 12.8
2. Xavier earns $11.50 per hour working at the nearby grocery store. Last week, Xavier worked for 13.5 hours. How much money did Xavier earn last week? Remember to round to the nearest penny.
The number of digits after the decimals in the factors tells us how many digits after the decimal in the product.
