Sparrow Creek Camp's Cooler: A Grade 1 Add and Subtract Worksheet

A grade 1 math worksheet where students solve add-to, take-from, put-together, and compare word problems about cups of water poured from a summer camp cooler.

Objectives

  1. Students will solve addition and subtraction word problems within 20 about cups of water.
  2. Students will find a missing addend or missing change amount in a word problem.

Vocabulary

Key words: cups, cooler, in all, left

Teacher overview

Sparrow Creek Summer Camp keeps one big water cooler on the picnic table for campers to fill their cups between swimming and hiking activities. This worksheet uses that single cooler, one day at camp, as the setting for eight word problems. Each problem asks students to add or subtract within 20, and the missing number moves around from problem to problem, so students cannot solve every item by using the same method every time. A teacher circulating during independent work should watch for students who reach for addition on every problem; problems 2, 4, and 8 each call for subtraction, and problem 6 asks "how many more" yet is also solved by subtracting.

Answer Key
  1. Answer: 17 cups. 12 + 5 = 17.
  2. Answer: 5 cups. 14 - 9 = 5.
  3. Answer: 14 campers. 6 + 8 = 14.
  4. Answer: 6 cups. 15 - 9 = 6, so the campers drank 6 cups.
  5. Answer: 6 cups. 7 + 6 = 13, so the counselor added 6 cups.
  6. Answer: 3 cups. 8 - 5 = 3 more cups for Team Blue.
  7. Answer: 5 cups. Team Green drank 3 fewer than Team Blue's 8 cups, so 8 - 3 = 5.
  8. Answer: 8 cups. 20 - 12 = 8 cups left.

Differentiation

Support

Give students 20 small counters (or paper cup cutouts) to physically add and remove as they read each problem, and circle the numbers in the problem before they choose to add or subtract.

Extension

Have students write their own ninth word problem about the water cooler, using a missing number somewhere other than at the end of the sentence, and trade papers with a partner to solve it.

ELL supports

Read each problem aloud twice before students begin, and provide a sentence frame for the answer: "There are ___ cups." Pair "in all," "left," and "more than" with a matching hand motion (open palms together for "in all," a sweeping-away motion for "left").
