Overview:

This learning activity is a great introduction for problem-solving using addition and subtraction to solve word problems within 20.

The video uses relatable objects, a friendly robot guide, and equations with a symbol for the unknown number to represent the problem. It includes the use of addition and subtraction strategies like counting on and how much more.

The video is engaging and offers 4 methods for adding and subtracting in a word problem. Students have the ability to add to or take from, and compare quantities to solve word problems within 20 like fewer or more than.

Students will follow along with the video using small concrete objects and illustrations to represent the word problems from the video. 

This activity was created as a result of the ALEX Resource Development Summit.

  Associated Standards and Objectives  
Content Standard(s):
Mathematics
MA2015 (2016)
Grade: 1
1 ) Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. (See Appendix A, Table 1.) [1-OA1]

Learning Objectives:

The students will be able to:
- use a variety of representations to solve word problems.
- justify and explain answers using concrete objects and drawings.

  Strategies, Preparations and Variations  
Phase:
Before/Engage
Activity:

  1. Show the video, Addition Subtraction Under 20 - 1st Grade Math Videos for Kids to engage students and introduce them to the variety of ways to solve word problems.
  2. The video demonstrates how to read and identify important operations in a word problem.
  3. Pause the video to discuss operational key words and allow students to ask questions.
  4. Pass out two different colored small concrete objects (counters, counting bears, buttons, etc.).
  5. Replay the video pausing between each word problem to allow time to use the small concrete objects (counters, counting bears, buttons, etc.) to represent the problem.
  6. Replay the video a 3rd time.
  7. Pause the video for each problem and ask students to identify the numbers being used.
  8. Have students explain the operation used (addition or subtraction).
  9. The students will illustrate the word problem in their journals/paper by drawing pictures of the object (hats, kittens, etc.) used in the video.
Assessment Strategies:

The teacher will walk around and observe students' work as they use small objects to represent the word problems.

Check students' illustrations for an understanding of the word problem and which operation was used.


Advanced Preparation:

The teacher will need:

  • the video Addition and Subtraction of Word Problems 
  • an internet-connected device
  • two different colored small concrete objects for each student
  • Journal/paper for each student to draw along with the video to illustrate each word problem. (Video has students draw to solve each problem.)
Variation Tips (optional):

This learning activity could be completed individually or with a partner.

Struggling students can be paired with a stronger partner.

Notes or Recommendations (optional):

ALCOS 2019

First 1.) Use addition and subtraction to solve word problems within 20 by using concrete objects, drawings, and equations with a symbol for the unknown number to represent the problem.

a. Add to with change unknown to solve word problems within 20.

b. Take from change unknown to solve word problems within 20.

c. Put together/take apart with addend unknown to solve word problems within 20.

d. Compare quantities, with difference unknown, bigger unknown, and smaller unknown while solving word problems within 20.
