Lesson 2-4 partition quotient 15 ÷ 3 = 5 6÷2=3 /Volum Ideas for Use • Group 2 or 3 common words. Add a word that is unrelated to the group. Then work with a friend to name the unrelated word. A number that is being divided. Circle the dividend in 12 ÷ 4 = . Then write the quotient. 3 • Design a crossword puzzle. Use the definition for each word as the clues. To separate into equal groups, to find the number of groups, or the number in each group. How can dividing help you share snacks with friends? Sample answer: I can put the food I am sharing in equal groups. The number by which the dividend is being divided. A number sentence using numbers and the ÷ sign. Write a division sentence in which the divisor is 5. Circle the divisor. Write an example of a division sentence. Then write the sentence using words. Sample answer: 20 ÷ 5 = 4 Sample answer: 9 ÷ 3 = 3; Nine divided by three equals three. Operations that undo each other, like multiplication and division. A group of related facts using the same numbers. Use inverse operations to write a multiplication and division sentence. Write the numbers in the fact family shown on this card. Sample answer: 5 × 6 = 30; 3, 9, 27 The answer to a division problem. To divide or “break up.” Write and solve a division problem. Circle the quotient. Partition can mean “a wall that divides a room into different areas.” How does that relate to the math word? Sample answer: 10 ÷ 5 = 2 Sample answer: Partition means to divide, the same way a wall divides a room Copyright © The McGraw-Hill Companies, Inc. 30 ÷ 6 = 5 Vocab Lesson 2-5 Lesson 2-3 related facts repeated subtraction 4 ⎧ ⎨ ⎩ Copyright © The McGraw-Hill Companies, Inc. ⎧ 3⎨ ⎩ 5 4 3 2 1 3 × 4 = 12 12 ÷ 4 = 3 0 2 4 6 10 ÷ 2 = 5 8 10 Ideas for Use Subtraction of the same number over and over again.
