The class has been identifying and comparing three attributes of objects: shape, color, and size. We will work with 2-dimensional and 3-dimensional shapes in future lessons. To prepare for this, help your child find objects with the shapes listed below. Also help your child find objects to bring to school for our Shapes Museum. The objects should not be valuable or breakable. Please return this Home Link to school tomorrow. Family Note Name Date Shapes 200 Copyright © Wright Group/McGraw-Hill HOME LINK 72 Practice 1.

The class has been working with 2-dimensional and 3-dimensional shapes. For today’s Home Link, help your child find 3-dimensional objects and then trace around one face of each object. Some examples are the bottom of a box, the bottom of a can, and the bottom of a cup. Use the back of this sheet and other sheets if you want. For each tracing, help your child find the name for the shape in the Word List and write the name on the tracing. Please return this Home Link to school tomorrow.

A picture or an object has symmetry if it can be folded in half so that the two halves match exactly. In today’s lesson, the class explored symmetry by cutting out designs from folded paper. To continue our exploration of symmetry, help your child find pictures that show symmetry in nature; for example, pictures of butterflies, leaves, animal markings, flowers, or snowflakes. Please return this Home Link to school tomorrow. Family Note Name Date Finding Symmetry in Nature 1. Find symmetrical pictures in magazines.

Copyright © Wright Group/McGraw-Hill 217 Mental Arithmetic, Money, and Fractions In Unit 8, children will examine a dollar bill and add the dollar to the money units they already know. They will continue to count and record amounts of money (using pennies, nickels, dimes, and quarters), often in more than one way. They will also begin learning how to make change. Children will also create addition, subtraction, and comparison problems for the class to solve and will share their own problem- solving strategies. Having children share their solution strategies is emphasized in Everyday Mathematicsand helps children feel more confident as they express their ideas. Later in Unit 8, children will work with fractions. They will be reminded that fractions are equal parts of wholes. When dealing with fractions, it is important that children keep in mind the “whole” or the ONE to which the fraction is linked. For example, 1 2of an apple and 1 2of a dollar are not the same because they deal with different types of “wholes.” HOME LINK 78 Name Date Unit 8: Family Letter Please keep this Family Letter for reference as your child works through Unit 8.

218 Vocabulary Important terms in Unit 8: fractional partsEqual parts of any whole. For example: One-third ( 1 3) of a whole 3-slice pizza has been eaten. Half ( 1 2) of the whole set of 4 eggs are broken. 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.Continue to review addition and subtraction facts. 2.Ask questions like the following: I want to buy an airplane that costs 27 cents. If I give the clerk 3 dimes, how much change will I get back? How can you show 14 cents using exactly 6 coins? (Have the actual coins available.) How many different ways can you show 14 cents? (Have the actual coins available.) 3.Count out 8 pennies (or any type of counter, such as buttons or paper clips). Ask your child to show you 1 2of the pennies and then 1 4of the pennies. Do this with a variety of different numbers. 4.Encourage your child to count various collections of coins you may have accumulated. Unit 8: Family Letter cont. HOME LINK 78 near doublesA strategy derived from the “doubles addition facts.” For example, a child might solve 3 4 by noting that 336, so 3 4 must be 1 more than 6, or 7.

Copyright © Wright Group/McGraw-Hill 219 Building Skills through Games In Unit 8, your child will practice addition, subtraction, place value, and money skills by playing the following games: Addition Top-It SeeMy Reference Book, pages 122–123. Players turn over two cards and call out the sum. The player with the higher sum keeps all the cards. The player with more cards at the end wins. Base-10 Exchange Players roll the dice and put that number of cubes on their Place-Value Mats. Whenever possible, they exchange 10 cubes for 1 long. The first player to make an exchange for a flat wins. One-Dollar Exchange SeeMy Reference Book, pages 144–145. Players roll the dice and put that number of cents on their Place-Value Mats. Whenever possible, they exchange 10 pennies for 1 dime. The first player to make an exchange for a $1 bill wins. 3, 2, 1, Game SeeMy Reference Book, pages 150–151. Players take turns subtracting 1, 2, or 3 from a given number. The first player to reach 0 exactly is the winner.flat long cube 1 flat 10 longs 100 cubes Unit 8: Family Letter cont. HOME LINK 78
