Benchmark Number: MA.K.A.1.2
Benchmark Description : Solve problems including those involving sets by counting, by using cardinal and ordinal numbers, by comparing, by ordering, and by creating sets up to 20.
Grade Level: K
Lesson Time: 15-20 mins
Objective: Given the numbered fish, the students will be able to form the physical addition and subtraction equations with 95% accuracy.
Materials: Paper fish numbered 1-20, dry erase board, marker, pencils, paper.
Procedure: Write an addition or subtraction sign on the board, move aboout three feet to the right then right an equal sign. Pass out a fish, pencil, and paper to each student. Explain that you are going to call out a problem. Example: #15 fish - #8 fish=. The students with these fish will fill in the appropriate spot on the board. The remaining students will use their pencils and paper to solve the problem. The person with the fish for the right answer will go up to the board and fill in the appropriate spot. Explain that this is an individual and group activity. At the end of the exercise students with high scores may be rewarded with stickers or pencils.
Evaluation:
Could the students physically
make the addition and subtraction equations? Could the students with the answers figure it
out or did they consistently need help to know they had the right answer? Did the students follow
directions? Were the students engaged in the activity?
