Understanding Mathematical Properties

In this lesson, students explored mathematical properties by replacing numbers with variables. The focus was on the additive identity property, where adding zero to a number returns the same number, and the multiplicative identity property, where multiplying a number by one returns the same number. The commutative property was also discussed, demonstrating that changing the order of numbers in addition or multiplication does not affect the result. Students used variables to generalize these properties.
