Help students learn to decompose numbers through 20 with this math center. Students will break down large numbers (on lily pads) by finding two or three smaller numbers (frogs) that are equivalent. Students may use the provided frog counters as manipulatives as needed. Encourage students to find various ways to build each number. Teacher tips and a student direction page help with easy center management. Black line masters are also included as ink saving alternatives.
