120 Copyright © Wright Group/McGraw-Hill We have begun to work on place value using base-10 blocks. The blocks shown in the tens columns are called longsand the blocks shown in the ones columns are called cubes. It takes 10 cubes to make 1 long. On this page, your child is writing numbers shown with longs and cubes. Please return this Home Link to school tomorrow. Family Note HOME LINK 5 1 Name Date Tens-and-Ones Riddles Example: 1.

Children continue to work with place value and base-10 blocks. In this lesson, children counted up and back by 10s from any number. On this page, your child will continue to explore what happens to the digits in a numeral when counting by 10s. Please return this Home Link to school tomorrow.

The symbol meansis less than,and the symbol meansis more than. These symbols will be used in the same way we use the symbol foris equal toorequals.For example, instead of writing 5 is less than8, we will write 58. It takes time for children to learn the correct use of these symbols. One way to help your child identify the correct symbol is to draw two dots near the larger number and one dot near the smaller number. Then connect the dots as shown below. 5 8 Another way is to think of the open end of the symbol as a mouth eating the larger number. 58 Family Note Write , , or .

Before doing the problems, it may be helpful for your child to sort real coins into groups (all of the dimes together, all of the nickels together). Many children are still learning to write amounts of money using dollars-and-cents notation. We will continue to practice this skill during the year. Please return this Home Link to school tomorrow.

Copyright © Wright Group/McGraw-Hill 143 Children are beginning to solve number stories in which they find how much more (or less) one number is than another. This is called the differencebetween the two numbers. Help your child line up the pennies in two rows and pair pennies in the top row with pennies in the bottom row. Have your child make as many pairs as possible. The extra pennies that could not be paired represent the difference. Please return this Home Link to school tomorrow.

For the next few days, children will return to basic addition facts. They will concentrate on memorizing the 0 and 1 facts (for example, 7 0 and 8 1), doubles facts (for example, 33), and facts that have a sum of 10 (for example, 3 7 and 6 4). Consider spending a short time each day practicing these addition facts with your child. Please return this Home Link to school tomorrow.

Turn-around addition facts are pairs of facts in which the numbers being added are the same. Turn-around facts have the same sum. For example, 2 35 and 3 25 are turn-around facts. Knowing about turn-around facts cuts down on the number of facts that have to be memorized: If you know a fact, you also know its turn-around fact. Please return this Home Link to school tomorrow.

HOME LINK 5 12 Name Date Family Letter Copyright © Wright Group/McGraw-Hill 153153 153 153 153 “What’s My Rule?” Today your child learned about a kind of problem you may not have seen before. We call it “What’s My Rule?” Please ask your child to explain it to you. Here is a little background information you may find useful. Imagine a machine with a funnel at the top and a tube at the bottom—we call this a function machine.The function machine can be programmed so that when you drop a number into the funnel at the top, the machine changes the number according to the rule and a new number comes out of the tube at the bottom. For example, you can program the machine to add 2 to any number that is dropped into the funnel. If you put in 3, out comes 5; if you put in 6, out comes 8. You can show this with a table: Here is another example of a function machine: in out 35 68 10 12 Rule out in 2 3 5 Rule out in 3 5 8 in out 58 69 25

154 Copyright © Wright Group/McGraw-Hill In a “What’s My Rule?” problem, some of the information is missing. To solve the problem, you have to find the missing information. The missing informati\ on can be the numbers that come out, the numbers that are dropped in, or the rule for \ programming the machine.

HOME LINK 5 14 Name Date Unit 6: Family Letter Copyright © Wright Group/McGraw-Hill 157157 Developing Fact Power Knowing the basic facts is as important to mathematics as knowing words by sight is to reading. Your child should begin to master many addition and subtraction facts by the end of the year. Learning the facts takes practice. It is not necessary to practice for a long time, but it is important to practice often. One good way to practice is to play the games described on the third page of this letter. Later in this unit, children will extend their time-telling skills by learning to tell time to the nearest 5 minutes and by representing the time in digital notation, as it appears on a digital clock. Please keep this letter for reference as your child works through Unit 6. Math Tools Your child will be using Fact Trianglesto practice and review addition and subtraction facts. Fact Triangles are a “new and improved” version of flash cards; the addition and subtraction facts shown are made from the same three numbers, and this helps your child understand the relationships among those facts. The Family Noteon Home Link 6-4, which you will receive later, provides a more detailed description of Fact Triangles. 347  ,

158 fact family A set of related facts linking two inverse operations, such as addition and subtraction. For example: 3 4 7 4 3 7 7 3 4 7 4 3 function machine An imaginary device that receives inputs and generates outputs. The machine usually pairs an input number with an output number by applying a rule such as “5.” name-collection box A diagram that is used for collecting equivalent names for a number. digital clock A clock that shows the time with numbers of hours and minutes, usually separated by a colon. range The difference between the maximum and minimum in a set of data. For example, in the set below, the range is 36288. middle value The number in the middle when the data are listed from smallest to largest. For example, in the data set below, 32 is the middle value: 28 28 31 32 33 35 36 “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.

Cover one of the other numbers for subtraction practice. Make this brief and fun. 2.Have your child tell you a number story that fits a given number model, such as 3 5 8. 3.Go to your local library and check out the book 12 Ways to Get to 11by Eve Merriam, an entertaining book that presents addition facts. 4.Fill in name-collection boxes. Begin with a number, such as 20, and find at least five equivalent names.

159 Addition Top-It Players turn over two cards and call out the sum. The player with the higher sum keeps all of the cards. The player with more cards at the end of the game wins. Fact Power Game Players take turns naming sums of addition facts on a game board. The player who correctly answers the greatest number of addition facts wins the game. Coin Exchange Players put 20 pennies, 10 nickels, and 2 quarters in a pile. At each turn, a player rolls 2 dice and collects the amount of money equal to the number of dots on the dice. Players make exchanges whenever possible. The game ends when there are no more quarters. The player who has the greatest amount of money wins.
