In the next lesson, we will extend our work with money to include dollars. In preparation for this, we have been practicing counting coins. If your child has difficulty with some problems on this page, use real coins to model the situations. Arrange the coins in groups of like coins and count the coins of the highest value first.

We are extending our work with base-10 blocks to include 100s. The base-10 block for 100 is called a “flat.” Note that the blocks are not always shown in the same order. If your child finds some of the problems difficult, you might model them with dollar bills (for flats), dimes (for longs), and pennies (for cubes). These make good substitutes for base-10 blocks. Ask your child to explain why there is a zero in the number in Problem 3. To practice reading 3-digit numbers, ask your child to read his or her answers to you.

We are beginning to explore the concept of fractions. Today, children focused on identifying fractional parts of things. We emphasized that fractional parts come from dividing something into equal parts. Please return this Home Link to school tomorrow. Family Note Name Date Exploring Halves and Fourths 1.

Today we extended our work with fractions to finding fractional parts of collections of objects. Help your child act out the problems below with pennies or counters. When sharing things equally, one strategy is to distribute the things just as you would deal cards in a card game and then count the things in one share. Please return this Home Link to school tomorrow. Family Note Name Date Sharing Sets of Objects Use pennies to help you solve the problems. 1. Halves: 2 people share 10 pennies equally.

HOME LINK 810 Name Date Unit 9: Family Letter Copyright © Wright Group/McGraw-Hill 245 Place Value and Fractions The concept of place value (ones, tens, hundreds, and so on) that children have worked on since Kindergarten Everyday Mathematicswill be taught on a more formal level in this unit. Patterns on number grids will be used to reinforce place- value concepts. For example, children may be asked to identify a hidden number on the number grid and to describe the strategies used to find and name that number. Once they are able to do this, they will solve number-grid puzzles— pieces of a number grid with all but a few numbers missing. Here are a few examples of number-grid puzzles: Children know that all numbers are written with one or more of these 10 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In order to reinforce this understanding, children will identify the place value of different digits in 2- and 3-digit numbers. Help your child remember that these same digits are also used to express quantities less than 1 with fractions. Later in this unit, children will extend their understanding of fraction concepts as they see relationships among fraction words, meanings, and symbols. 53 43 73 23 79 90 59 69 one-third 1 3 Please keep this Family Letter for reference as your child works through Unit 9.

246 Copyright © Wright Group/McGraw-Hill Vocabulary Important terms in Unit 9: 2-digit numbersIn base 10, numbers from 10 through 99 that have two digits each. 3-digit numbersIn base 10, numbers from 100 through 999 that have three digits each.denominatorThe bottom number in a fraction. The number of equal parts into which the whole is divided. numeratorThe top number in a fraction. The number of equal parts of the whole that are being considered.  2 4  Do-Anytime Activities To work with your child on concepts taught in this unit and in previous units, try these interesting and rewarding activities: 1.Ask questions, such as the following: What is the fraction word for each of 4 equal parts of something?(fourths)Each of eight equal parts?(eighths) 2.Give your child several pieces of paper to fold into halves, fourths, or eighths. He or she can label each part with the appropriate fraction symbol ( 1 2,1 4,1 8). 3.Using a set of numbers, have your child write the largest and smallest 2- and 3-digit whole numbers possible. For example, using 5, 2, and 9, the largest whole number is 952; the smallest is 259. 4.Say a 2- or 3-digit number. Then have your child identify the actual value of the digit in each place. For example, in the number 952, the value of the 9 is 900, the value of the 5 is 50, and the value of the 2 is 2 ones, or two. An important goal of Everyday Mathematicsis for children eventually to think of any digit in a multidigit number by its place-value name. Unit 9: Family Letter cont. HOME LINK 810

Copyright © Wright Group/McGraw-Hill 247 Building Skills through Games In Unit 9, your child will practice addition skills by playing the following games: Number-Grid GameSeeMy Reference Book, pages 142–143. Each player rolls a die and moves his or her marker on the number grid. The first player to get to 110 or past 110 wins. Fact Power GamePlayers take turns rolling a die and moving their markers on the game mat. Players then say the sum for the addition fact on the game mat. Unit 9: Family Letter cont.
