COMPARING AND ORDERING NUMBERS Parent Pointer Knowing how to compare and order numbers is a skill we use every day. Knowing if you have enough money to make a purchase, knowing which movie is longer than another, and even finding out if a friend is older than you are all done by comparing and ordering numbers. Your child is currently using the greater than, >, less than, <, and equal to, =, symbols to compare whole numbers. This is a basic skill that will be built upon as your child progresses through school. Math in the Home, on the Go, and for the Fun of It DIRECTIONS: Read through the Greater than, Less than, Equal To reference sheet with your child. Go step by step to make sure your child understands how to compare numbers using these symbols. Talk about the Remember section, since using the alligator s mouth helps many children remember the difference between the two signs. Take time to discuss the Think about it questions at the bottom of the page. Then, move on to the Which Symbol? activity page, where you need to choose the symbol that makes a correct comparison. Talk about It After you have finished the activity, turn to The Back Page to have your child show what he or she knows. Now go have some fun with the activity!

Greater than, Less than, Equal To Greater than > The greater than sign is used when the first number is larger than the second number. Here are two numbers, 43 and 22. We use place value to decide which number is larger. The digits in the tens column are 4 and 2. Since 4 is larger than 2, 43 is larger than 22. Remember - The alligator always eats the larger number: 43 22 Place the symbol between the numbers. 43 > 22 To read this, we say 43 is greater than 22. Less than < The less than sign is used when the first number is smaller than the second number. Here are two numbers, 7 and 9. We use place value to decide which number is smaller. Since there are only values in the ones column, we compare these numbers, 7 and 9. Place the symbol between the numbers. 7 < 9 To read this, we say 7 is less than 9. The equal to sign is used when the first number and the second number have the same value. Equal to = Here are two numbers: 18 and 18. They are both the same number, so they have the same value. Place the symbol between the numbers. 18 = 18 To read this, we say 18 is equal to 18. Think about it - How do you find out which number is larger if one has a digit in the tens place and one only has a digit in the ones place? How do you find the larger number if they both have the same digit in the tens column? Grade 1 Compare and Order Whole Numbers Using Symbols 2004 Evans Newton Incorporated 3

Which Symbol? Materials: Directions: Cut out the cards below. Keep them separate. Cut out the cards from the next page. Mix them up and place them facedown in a pile. You go first. Take the top card from the pile and compare the numbers on the card. Decide which symbol belongs between them to correctly compare the numbers: <, >, or =. Hold up the card that shows the symbol you chose. If you both agree that the symbol you chose is correct, write the symbol on the card, and you keep the card! If you do not agree, mix the card back into the pile. Take turns taking cards. The person with the most cards WINS! < > = Grade 1 Compare and Order Whole Numbers Using Symbols 2004 Evans Newton Incorporated 4
