Addition Concepts and Commutative Property

Miss Judy introduces addition using 10 frames, focusing on the problem 8 + 4. She demonstrates how to use visual aids like counters to represent numbers and transform the problem into a simpler form, 10 + 2, by making 10. The lesson concludes with a review and explanation of the commutative property of addition, showing that 8 + 4 and 4 + 8 both equal 12.
