A Learning Activity is a strategy a teacher chooses to actively
engage students in learning a concept or skill using a digital tool/resource.

During/Explore/Explain
Activity:
Explain to the students that a number bond is used to show how 2 parts can make a whole and a whole can be broken into 2 parts.
Choose any number less than or equal to 10.
Give students a small lunch sack that contains the 10 monkeys and the 10 alligators that were provided to you for printing.
Without looking, have students reach into the bag and pull out 1 object (for this game, picture cards of alligators and monkeys) at a time until they have displayed the given number.
Show the students how they can place all of the monkeys and alligators on the circle labeled whole on the number bond mat.
Next have them move the monkeys to one of the small circles labeled part and the alligators to the other small circle labeled part on the number bond mat.
Explain that the 2 parts make up the whole.
Encourage the students to verbalize with the group or partner, their decomposition on the number bond mat (I know that 7 is 3 and 4).
Continue to play this game using different numbers less than or equal to 10.
Once the students have practiced a few times on the number bond mat, have them represent one of their decompositions in their math journal. Students should use drawings and/or numerals for their representation.
Assessment Strategies:
While students are counting out the monkeys and alligators, the teacher will observe students using one to one correspondence.
While students are working on the number bond mat, the teacher will drop in and listen to see if the student can verbalize the parts and the whole.
Students are able to represent their quantity in their math journal using drawings and/or numerals.
Advanced Preparation:
The teacher will need to print and cut out the alligators and monkeys for each student.
The teacher will need to print the number bond mat for each student and laminate for this lesson.
Variation Tips (optional):
Once the students have mastered verbalizing and representing their decompositions, then move the student towards writing an equation to represent their decomposition (7=3+4 or 3+4=7).
As you drop and listen, have students cover 1 of the parts or the whole on the number bond mat with a cup and have the partner guess the missing part or whole.
Notes or Recommendations (optional):
10. Decompose numbers less than or equal to 10 into pairs of smaller numbers in more than one way, by using concrete objects or drawings, and record each decomposition by a drawing or equation. Example: 5 = 2 + 3 and 5 = 4 + 1
