162 Copyright © Wright Group/McGraw-Hill Children continue practicing addition facts. Today they learned how to use the facts table to find sums. Have your child explain how the table shows the fact 6814. Help your child find sums in the table. It is fine to solve the problems using other strategies, such as counting on or using counters to model the problems. Please return page 163 to school tomorrow. Keep the facts table at home for future use.

Today we began working with name-collection boxes. See the attached letter for more information about this routine. Please return this Home Link to school tomorrow. Family Note HOME LINK 62 Name Date Name-Collection Boxes 1. List all of the addition facts you know that have a sum of 10. 2. Write as many names as you can in the name-collection boxes.

Copyright © Wright Group/McGraw-Hill 165 Name Date Family Letter Name-Collection Boxes People, things, and ideas often have several different names. For example, Mary calls her parents Mom and Dad. Other people may call them Linda and John, Aunt Linda and Uncle John, or Grandma and Grandpa. Mail may come addressed to Mr. and Mrs. West. All of these names are for the same two people. Your child is bringing home an activity with a special format for using this naming idea with numbers. We call this format a name-collection box. The box is used by children to collect many names for a given number. The box is identified by the name on the label. The box shown here is a 25-box, a name- collection box for the number 25. Names can include sums, differences, products, quotients, or combinations of operations, as well as words (including words in other languages), tally marks, and arrays. A name- collection box can be filled by using any equivalent names. With repeated practice, children gain the power to rename numbers for a variety of different uses.

Copyright © Wright Group/McGraw-Hill 169 We have extended our work with facts to subtraction facts by introducing fact families. Your child will generate addition facts and subtraction facts for the numbers pictured on the dominoes below. Note that for each problem, there are two addition facts and two subtraction facts.

LESSON 64 Name Date Fact Triangle 170 Copyright © Wright Group/McGraw-Hill  , 

Copyright © Wright Group/McGraw-Hill 171 Name Date Family Letter HOME LINK 64 Fact Triangles Your child should cut apart the triangles on page 172. Notice that each triangle has the three numbers used in a fact family on it. Use these triangles like flash cards to practice addition and subtraction facts. The number below the dot is the sum of the other two numbers. For example, 8 is the sum of 5 and 3. To practice addition, cover the sum. Your child then adds the numbers that are not covered. For example, if you cover 8, your child adds 5 and 3. To practice subtraction, cover one of the numbers at the bottom of the triangle. Your child then subtracts the uncovered number at the bottom from the sum. For example, if you cover 3, your child subtracts 5 from 8. If you cover 5, your child subtracts 3 from 8. Fact Triangles have two advantages over regular flash cards. 1.They reinforce the strong link between addition and subtraction. 2.They help simplify the memorizing task by linking four facts together. Knowing a single fact means that you really know four facts. 538 358 853 835 Save this set of Fact Triangles in an envelope or a plastic bag to continue practicing addition and subtraction facts with your child when you have time. 538  ,

If your child is having difficulty because coins are not shown in any particular order, use real coins to model the problems. Sort the coins into groups of like coins (all dimes together, all nickels together) before counting. Children also continue to use dollars-and-cents notation (for example, $1.05). If your child has trouble recording amounts in this notation, don’t worry—this is a skill we will continue to practice throughout the year. Please return this Home Link to school tomorrow.

192 Copyright © Wright Group/McGraw-Hill Name Date Unit 7: Family Letter Geometry and Attributes In Unit 7, children will work with 2-dimensional shapes. First, children will classify blocks by their shape, color, and size. Then they will learn to recognize attributes such as number of sides and square corners. Later they will build their own shapes out of straws and twist-ties, identifying the differences among shapes that are polygons and shapes that are not. HOME LINK 613 In the last lesson of this unit, children will explore symmetry. They will find symmetrical shapes in real life, including butterflies, bells, guitars, vases, and double dominoes. Then they will create their own symmetrical shapes, using paper and scissors. Please keep this Family Letter for reference as your child works through Unit 7. Children will work with 3-dimensional shapes they encounter every day. They will be asked to bring objects from home, which will be organized and labeled to create a “Shapes Museum” for the classroom. For example, a soup can would be labeled “cylinder”; a tennis ball, “sphere.” In examining the shapes brought to class, children will begin to identify similarities and differences among five kinds of 3-dimensional shapes: prisms, pyramids, spheres, cylinders, and cones. They will learn to identify characteristics, using terms such as flatandround. We will use the names of the shapes in class, but children will not be expected to memorize their definitions.

Copyright © Wright Group/McGraw-Hill 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.Draw a name-collection box with a number on the tag. Ask your child to write at least 10 equivalent names for the given number. 2.Occasionally ask questions about time: What time is it? What time will it be in five minutes? In ten minutes? In one hour? 3.Continue to work on addition and subtraction facts using Fact Triangles, short drill sessions, and any of the games introduced at school. 4.If a calculator is available, ask your child to show you how to count with it. See how high your child can count on the calculator. 5.Look for geometric shapes around the house, at the supermarket, as part of architectural features, and on street signs. Begin to call these shapes by their geometric names. 12 175 210 48 131 twelve doce ////\ ////\//• • • • • • • • • • • • 194 Unit 7: Family Letter cont. HOME LINK 613

195 Building Skills through Games In this unit, your child will practice classification and place-value skills by playing the following games: Attribute Train Game One player puts down a block. The next player finds a block that differs in only one attribute—shape, size, or color—from the first block and puts it next to the first block. Each player continues to add to the “train” of blocks. Tens-and-Ones Trading Game 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! As You Help Your Child with Homework As your child brings assignments home, you may want to go over the instructions together, clarifying them as necessary.
