Your child is beginning to read a thermometer marked in two-degree intervals. A skill that will help your child with reading temperatures is to count by 2s. Begin with multiples of 10 (numbers such as 10, 20, 30, and so on). For example, start at 50 and count by 2s: 50, 52, 54, 56, 58, 60, and so on. Please return this Home Link to school tomorrow.

In today’s lesson, we measured objects using nonstandard units such as digits (finger widths), hands, fathoms (arm spans), and hand spans. One of our discoveries is that we get different measurements for the same object if different people do the measuring using these units. We will continue this investigation, eventually realizing that standard units, such as feet and inches, provide us with more reliable measurements. Help your child measure his or her bed using hand spans. See drawing below. Please return this Home Link to school tomorrow.

HOME LINK 4 13 Name Date Unit 5: Family Letter Place Value, Number Stories, and Basic Facts As their work in mathematics progresses, children are beginning to use larger numbers. In Unit 5, children will begin to explore the system we use for writing large numbers by focusing on the idea of place value. For example, in the number 72, 7 is in the tens place, so there are “7 tens,” and 2 is in the ones place, so there are “2 ones.” Children will use base-10 blocks to represent numbers and to find the sums of two numbers. They will also use place value to determine “greater than” and “less than” relationships. Later in this unit, children will continue to work with addition facts. Shortcuts for learning facts will be introduced. One shortcut is the turn-aroundrule, which states that the order in which numbers are added does not change the sum. For example, 43 and 3 4 both equal 7. Your child will also learn the meaning of adding 0 and 1 to any number. Knowing these shortcuts will make the task of learning addition facts easier. Children will also practice place value and addition and subtraction facts by acting out number stories. They will act out these stories using concrete objects and will begin to represent the stories with number models.(See this unit’s vocabulary list for more information on number models.) Children have explored many number patterns in previous lessons. “What’s My Rule?” is a routine introduced in this unit and found throughout Everyday Mathematicsthat provides practice with number patterns and number relationships. You will receive more detailed information about this routine when we begin to use it in class. Please keep this Family Letter for reference as your child works through Unit 5. turn-around addition facts tens ones 72 Copyright © Wright Group/McGraw-Hill 115

116 Copyright © Wright Group/McGraw-Hill Vocabulary Important terms in Unit 5: cube In Everyday Mathematics, a base-10 block that represents 1. long In Everyday Mathematics, a base-10 block that represents 10. flat In Everyday Mathematics, a base-10 block that represents 100. place value In our standard, base-10 system for writing numbers, each place has a value 10 times that of the place to its right and 1 tenth the value of the place to its left. For example, in the number 54, the 5 represents tens, and the 4 represents ones. number model A number sentence that models a number story. For example, 7310 is a number model for the number story: 254 hundreds tensones Seven lions are lying in the sun. Three more lions join them. How many lions are there altogether? turn-around addition facts A pair of addition facts in which the order of the addends is reversed. For example, 5 4 9 and 4 5 9 are turn- around addition facts. doubles addition facts The sum of a 1-digit number added to itself. For example, 5 5 10, 2 2 4, and 6 6 12 are all doubles addition facts. A doubles addition fact does not have a turn-around addition fact partner. function machine An imaginary device that receives inputs and generates outputs. A number (input) is put into the machine and is transformed into a second number (output) through the application of a rule. “What’s My Rule?” problem A problem in which two of the three parts of a function (input, output, and rule) are known, and the third is to be found out.

Copyright © Wright Group/McGraw-Hill 117 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.Tell addition and subtraction number stories to your child. Have your child solve the problems using various household objects, and then record the answers in number models. 2.Encourage your child to make up some number stories. Building Skills through Games In this unit, your child will practice addition, subtraction, and place-value skills by playing the following games: Base-10 Exchange Players take turns putting base-10 blocks on their Tens-and-Ones Mat according to the roll of a die. Whenever possible, they exchange 10 cubes for 1 long. The first player to get 10 longs wins. Beat the Calculator A “Calculator” (a player who uses a calculator) and a “Brain” (a player who does not use a calculator) race to see who will be first to solve addition problems. Difference Game Players pick a card and collect as many pennies as the number shown on the card. Then players count each other’s pennies and figure out how many more pennies one player has than the other. Digit Game Each partner draws two cards from a set of number cards. The player whose cards make the larger number takes all of the cards. The player with more cards at the end of the game wins. Penny-Nickel-Dime Exchange Partners place 20 pennies, 10 nickels, and 10 dimes into a bank. Players take turns rolling two dice, collecting the amount shown on the dice from the bank. Partners exchange pennies and nickels for dimes until all of the dimes are gone. The player who has more dimes wins. Unit 5: Family Letter cont. HOME LINK 413
