After reading aloud the story, "If you give a mouse a cookie...", students can practice even and odd numbers using a cookie jar & cookies template. I put 6 cookie jars on 1 sheet to give you a set of 3 per page vertically. I also put 4 sets of cookies on one document to save copies for teaching materials. Students color the cookies and then arrange the correct number (odd or even) by gluing the cookies inside the jar. My students cut out the jars first, glued them on construction paper, and then proceeded to color/cut/glue the cookies onto the jars. Each student receives 2 cookie jars and 1 set of cookies for this activity.
