Properties of Even and Odd Numbers

The lesson covers the concepts of odd and even numbers, explaining their properties and how they relate to addition, multiplication, and division. Students learn that the sum of two even numbers or two odd numbers is even, while the sum of an even and an odd number is odd. In multiplication, the product of two even numbers is even, the product of two odd numbers is odd, and the product of an even and an odd number is even. These rules are applied to division to help determine factors and quotients. The lesson concludes with instructions for homework and an exit ticket.
