Alex: Cracker Math (Commutative Property)

During this lesson students will listen to the story FISH EYES: A BOOK YOU CAN COUNT ON by Lois Ehlert and use concrete objects to explore the commutative property of addition. During this lesson students will be guided through exercises to strengthen knowledge that the order of the addends has no effect upon the sum. In mathematical terms, a+b=b+a. They will also use the internet to practice what they have learned during this lesson.
