The video demonstrates how to read and identify important operations in a word problem.
Pause the video to discuss operational key words and allow students to ask questions.
Pass out two different colored small concrete objects (counters, counting bears, buttons, etc.).
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.
Replay the video a 3rd time.
Pause the video for each problem and ask students to identify the numbers being used.
Have students explain the operation used (addition or subtraction).
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.
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.

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.
