Activities to Try at Home
Multiplying and Dividing with Fractions In this unit, students multiply and divide with fractions. Look for familiar and interesting situations that you can use as a basis for exploring these types of problems with your child. For example, when you are cooking with your child, ask questions like these:
Encourage students to draw representations to solve these problems
Multiplying and Dividing Decimals In this unit, students also multiply and divide with decimals. Look for familiar and interesting situations that you can use as a basis for exploring these types of problems with your child. Here are some examples:
Converting Measurements In this unit, students convert measurements for distances, mass/weight, and capacity within the metric system and within the U.S. standard system. Have your child help you convert measurements that you use in your daily lives, such as converting meters to centimeters, ounces to pounds, inches to feet, quarts to gallons, and liters to milliliters.
How Did You Solve That? Ask your child to tell you about how he or she is solving problems. Also ask your child to record his or her work so that you can understand it. If some of the strategies your child is using are unfamiliar to you, ask your child to explain them carefully. Learning to clearly communicate one’s thinking to others is an important emphasis in this unit.
