156 Name Date Time Sometimes the order in which you add numbers 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 (401959). 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. Please return this Home Link to school tomorrow. For each problem:  Think about an easy way to add the numbers.  Write a number model to show the order in which you are adding the numbers.  Find each sum. Tell someone at home why you added the numbers in that order.

159 Name Date Time Today your child learned about a device that is useful when solving number stories. We call it a comparison diagram. Diagrams like these can help your child organize the information in a problem. When the information is organized, it is easier to decide which operation (, , , or ) to use to solve the problem. Comparison diagrams are used to represent problems in which two quantities are given and the question is how much more or less one quantity is than the other (the difference). Example 1:There are 49 fourth graders and 38 third graders. How many more fourth graders are there than third graders? Note that the number of fourth graders is being compared with the number of third graders. • Answer:There are 11 more fourth graders than third graders. • Possible number models: Children who think of the problem in terms of subtraction will write 49 38 11. Other children may think of the problem in terms of addition: “Which number added to 38 will give me 49?” They will write the number model as 38 11 49. Example 2:There are 53 second graders. There are 10 more second graders than first graders. How many first graders are there? Note that sometimes the difference is known and that one of the two quantities is unknown. • Answer:There are 43 first graders. • Possible number models: 53 10 43 or 10 43 53 For Problems 1 and 2, ask your child to explain the number model that he or she wrote. Also ask your child to explain the steps needed to solve Problems 4 – 6. Please return the second pageof this Home Link to school tomorrow.

188 Name Date Time In this lesson, your child worked on the concept of division by putting objects into equal groups and sharing objects equally among several people. Objects that are left over are called the remainder.If 9 books are shared equally among 4 people, each person gets 2 books, and the 1 book that is left over is the remainder. Watch as your child divides things equally among family members. Try to use groups of objects that can be divided with no remainder as well as groups that have remainders. Please return this Home Link to school tomorrow. 1. Have someone at home give you a group or handful of small items, such as raisins, buttons, or popcorn. Show how you can divide the items equally among your family members. Are any items left over? Make a record of what you did. Be ready to tell about it in class.

191 Name Date Time Copyright © Wright Group/McGraw-Hill HOME LINK 6 11 Unit 7: Family Letter Patterns and Rules In Unit 7, children will concentrate on number patterns, computational skills, and the application of mathematics through the use of data. They will continue to use the 100-grid to support their numeration skills. Children will also explore the patterns of doubling and halving numbers, which will help prepare them for multiplication and division. Computational work will be extended to several 2-digit numbers and to the subtraction of 1- and 2-digit numbers from multiples of 10. Children will learn to find complements of tens; that is, they will answer such questions as “What must I add to 4 to get to 10? What must I add to 47 to get to 50?” or “How many tens are needed to get from 320 to 400?” Children will also collect and work with real-life data about animals, adults, and themselves. For example, they will collect data by measuring the lengths of their standing long jumps and then find the median jump length for the class. jump measure Please keep this Family Letter for reference as your child works through Unit 7.

Copyright © Wright Group/McGraw-Hill Vocabulary Important terms in Unit 7: median (middle number) The number in the middle of a list of data ordered from least to greatest or vice versa. For example, 35 is the middle number in the following ordered list. 30, 32, 32, 35, 36, 38, 40 frequency The number of times an event or value occurs in a set of data. For example, in the set of data above, 32 has a frequency of 2. Do-Anytime Activities To work with your child on the concepts taught in this unit and in previous units, try these interesting and rewarding activities: 1.If you have a calculator at home, practice making (and breaking) tens. For example: Making tens: Enter 33. What needs to be done to display 50? 33 50 Breaking tens: Enter 60. What needs to be done to display 52? 60  52 Or, for more challenging practice, try the following: Enter 27. What needs to be done to display 40? Enter 90. What needs to be done to display 66? Try other similar numbers. 2.Make a game out of doubling, tripling, and quadrupling small numbers. For example, using the number 2, first double it. What number do you get? Continue the doubling process five more times. Start again with the number 2 and triple it; then quadruple it. Discuss the differences among the final numbers. 3.Collect a simple set of data from family and friends. For example, how high can different people’s fingertips reach while the people are standing flat on the floor? Order the data to find the median. 192 Unit 7: Family Letter cont. HOME LINK 611

193 Copyright © Wright Group/McGraw-Hill Building Skills through Games In Unit 7, your child will practice skills related to addition and subtraction as well as chance and probability by playing the following games: Array Bingo Players roll the dice and find an Array Bingocard with the same number of dots. Players then turn that card over. The first player to have a row, column, or diagonal of facedown cards calls out “Bingo!” and wins the game. Soccer Spin Players choose a spinner to use during the game. They choose a team to cheer for, Checks or Stripes. They then predict which team will win based on their spinner. They spin the spinner to check their prediction. Basketball Addition The basketball game is played by two teams, each consisting of 3–5 players. The number of points scored by each player in each half is determined by rolling a twenty-sided polyhedral die or 3 regular dice and using their sum. The team that scores the greater number of points wins the game. Hit the Target Players choose a 2-digit multiple of ten (10, 20, 30, and so on) as a target number. One player enters a starting number on a calculator and tries to change the starting number to the target number by adding a number to it on the calculator. Children practice finding differences between 2-digit numbers and higher multiples of tens. Unit 7: Family Letter cont. HOME LINK 611
