Lesson 16
4. The product of two even numbers is even.
One example answer:
Using the problem 𝟔×𝟏4, students know that this is equivalent to six groups of fourteen, or
We know that the sum of two even numbers is even; therefore, when adding the addends two at a time, the sum will always be even.
This means the sum of six even numbers will be even, making the product even since it will be equivalent to the sum.

Lesson 16
5. The product of two odd numbers is odd.
One example answer: Using the problem 𝟓x 𝟏5, we know that this is equivalent to five groups of fifteen, or
We also know that the sum of two odd numbers is even, and the sum of an odd and even number is odd.
When adding two of the addends together at a time, the answer will rotate between even and odd.
When the final two numbers are added together, one will be even and the other odd.
Therefore, the sum will be odd, which makes the product odd since it will be equivalent to the sum.

Lesson 16
6. The product of an even number and an odd number is even.
One example answer: Using the problem 𝟔 x 𝟕, students know that this is equivalent to the sum of six sevens, or 𝟕+𝟕+𝟕+𝟕+𝟕+𝟕.
You know that the sum of two odd numbers is even, and the sum of two even numbers is even.
Therefore, when adding two addends at a time, the results will be an even number.
Calculating the sum of these even numbers will also be even, which means the total sum will be even.
This also implies the product will be even since the sum and product are equivalent.
