This activity allows students to show their understanding of decomposing numbers by creating a flower with all of the expressions written on the petals. This activity can be used as a post-assessment at the end of your decomposition unit.
You will need to run off all flower materials ahead of time on colored construction paper (petals, stem/leaves and centers). Students will create their own decomposition flower by choosing any number 6, 7, 8, 9 or 10. They will write the number on a circle, choose a tool for decomposing, and write the expressions on the flower petals to attach to their circle. When they are done finding all the different expressions, they will glue on the petals last. All pieces will have been cut out and the stem and circle were glued ahead of time so that students are not wasting time cutting/gluing.
This activity aligns to the following common core standard:
K.OA.4 For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
