Divide Multi-Digit Numbers by One-Digit Numbers
Dear Family,
In this chapter, your student is learning about dividing multi-digit numbers by one-digit numbers. Students will use tape diagrams, counters, and area diagrams when dividing. Students will explore division problems with and without a remainder. Students will use a division strategy involving partial quotients, where quotients are found in parts until the remainder is less than the divisor. You can help your student learn about dividing multi-digit numbers by one-digit numbers by practicing in real-life settings. Vocabulary terms associated with this chapter include remainderand partial quotients.
At the grocery store, you can find items to help model division. For example, there may be a cereal box containing 80 ounces. The box of cereal may have a serving size of 3 ounces. Here are some questions to ask your student at the store. (You can choose any product, but you may want to round the price to the nearest dollar.)
Help your student find items that can be shared with many people. There should be at least 3 items available. Then ask your student to complete the following.
By the end of this chapter, your student should feel confident with the learning targets and success criteria on the next page. Encourage your student to think of other contexts in which to use division.
Have fun exploring division!
