Mathemorphosis Common Core Alignment

Age Appropriateness/Rationale

Use your addition or subtraction skills to help the caterpillar "mathemorphosize" to a beautiful butterfly. Each time you answer a math problem correctly, your caterpillar will chew up a leaf and get larger. If you keep answering questions correctly, your butterfly will form a cocoon (chrysalis) around itself until it bursts out as one of four different kinds of butterflies.

Mathemorphosis is perfect for kids ages 5 – 7, Grade Levels: K – 2.2 (apx.)
