Missing Addends
Family Note
In this lesson your child used mental strategies to find differences between 2-digit numbers and larger multiples of 10. For example, your child found what number added to 44 equals 50. (The answer is 6.) In Problems 1–2 your child will find the difference between a number and the next larger multiple of 10. In Problem 3 your child will find different combinations of numbers that add to 70. If your child has difficulty with this problem, suggest first adding 1s to the first number in each combination to find the next-larger multiple of 10. For example, add 2 to 48 to make 50. Then add 20 (or two 10s) to 50 to make 70. Finally, add 2 + 20 to find the answer, 22. So 48 + 22 = 70.

Question 3.
Make 70s. Show someone at home how you did it.
Answer:
Explanation:
An addition sentence is a mathematical expression that shows two or more values added together. By adding 1s to the first number in each combination is used to find the next-larger multiple of 10.
Add 2 to 48 to make 50. Then add 20 (or two 10s) to 50 to make 70. Finally, add 2 + 20 to find the answer, 22. So 48 + 22 = 70.
Add 8 to 32 to make 40. Then add 30 (or three 10s) to 40 to make 70. Finally, add 8 + 30 to find the answer, 38. So 32 + 38 = 70.
Add 5 to 65 to make 70. So 65 +5 = 70.
Add 60 to 10 to make 70. So 10 + 60 = 70.
Add 7 to 43 to make 50. Then add 20 (or two 10s) to 50 to make 70. Finally, add 7 + 20 to find the answer, 27. So 43 + 27 = 70.
Add 1 to 19 to make 20. Then add 50 (or five 10s) to 20 to make 70. Finally, add 1 + 50 to find the answer, 51. So 19 + 51 = 70.
Add 9 to 51 to make 60. Then add 10 (or one 10) to 60 to make 70. Finally, add 9 + 10 to find the answer, 19. So 51 + 19 = 70.
Add 3 to 27 to make 30. Then add 40 (or four 10s) to 30 to make 70. Finally, add 3 + 40 to find the answer, 43. So 27 + 43 = 70.

Adding Three or More Numbers
Family Note
Today your child added more than 2 addends. Changing the order of the addends can make it easier to find the sum. For example, when adding 17, 19, and 23, some people may first calculate 17 + 23, which equals 40, and then add 19 (40 + 19 = 59). For Problems 1–4, help your child look for easy combinations. Before working on Problems 5–10, you might go over the example with your child.

Measuring Height
Family Note
In this lesson your child was introduced to a metric unit of length called the meter. One meter is equal to 100 centimeters. We compared metersticks to yardsticks and noticed that 1 meter is a little longer than 1 yard. Then we used tools such as rulers, yardsticks, metersticks, and tape measures to measure lengths. Your child may wonder why there are two standard units—yards and meters—that
are nearly the same size. You may want to explore this issue by searching online for information about the metric and U.S. customary systems of measurement.
If you don’t have tools to measure length with metric units at home, you and your child can cut
pieces of string or strips of paper to match the heights of a table and an adult. Your child can bring
the string or strips to school to measure.
