Week of April 20
We are continuing working on Chapter 7. We have been working on decimal division. In this chapter, your student is learning about division of decimals. The first lesson shows patterns for dividing by powers of 10. The next lesson uses
compatible numbers to estimate quotients. Using models helps students to
make sense of quotients involving decimals. Your student will learn how to place the decimal point in the quotient and how to work with zeros in the dividend.
Finally, your student will solve multi-step word problems to apply what he or
she has learned.
There are many situations that you can use to help your student understand
division of decimals.
• Measure the length and width of a room in meters. Multiply to find the
area. Give your student the area and the length of the room. Then ask,
“What is the width, in meters?” Have your student first estimate the
answer and then divide to find the actual answer. Ask, “Does your
answer make sense, based on your estimate?”
• Use a grocery receipt as an opportunity to divide decimals when you
buy apples or some other food by the pound. Say, “We spent $3.12 on
apples that cost $1.98 per pound. How many pounds of apples did we
buy?”
• Have your student find the unit price of an item. Say, “A 64-ounce
bottle of juice costs $3.87. What is the unit price?”
• Divide money equally among people. Choose an amount of money, such as
$5.73. Ask, “Can you divide the money equally among 3 people? If so,
how much would each person get?”
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 use and practice the skills of dividing decimals routinely.
Have fun dividing decimals!
