There are two dog mats. One has "even" written on it and the other has "odd" written on it. There are 24 colorful bones. Students will read the number on the bone and place it on the correct doggy mat. You can use as whole group to introduce even and odd numbers or you can use as a review. You can also place in math stations so that students can work independently. An answer key is included. This is brought to you by "PRECIOUS ITEMS." If you look at the answer key in the view portion you can see what numbers were used for this activity.
