### PRODUCT DESCRIPTION

Students can practice determining when a product will be odd or even by doing this sorting activity. Knowing when a product should be odd or even is a great strategy to use when multiplying. It can help them to self-check and determine if their answer is reasonable.

In multiplication, students may not always correctly use the strategies they have learned to do when they don't know a fact, such as equal groups or repeated addition. They may only be 1 or 2 off in their answer, but incorrect all the same. Because of this, it is very important for them to know if their answer makes sense. That's why knowing when a product should be odd or even will come in!

For example if a student multiplies 7 x 3 and gets 22 as their product, they can look at their answer and think, "Does this make sense?" This is when they will (hopefully if they are using this strategy correctly) look at the factors and determine that they are both odd so the product must also be odd. However, their product is even. This is when they will know that they need to go back and figure out what they did wrong to get the CORRECT answer.

This activity is self-checking in that it has QR codes that tell them if their product is odd or even. QR codes = instant fun! :) In addition, I have also created an individual quick check to go with this activity. In the activity, they must both sort the problems based on if they have odd or even products AND solve them. An answer key is included with this.
