We know that our students are not fluent in their facts to 20, so we included in our the directions that students may use manipulatives or paper and a pencil to help solve the equations. If we are going to tell parents that, then we also need to show them that. So, to go along with the game boards, I also created manipulative mats.
I like to teach my students the activities the parents will get at the meeting beforehand to get them excited about it. Knowing the addition and subtraction to 20 games will be difficult, I also created versions to 5, 10 and 15 and introduced the lower boards first. They absolutely LOVE them!!
I glued each level back-to-back (addition/subtraction) with construction paper in between and laminated them. We used beans as counters because that is something that might be used at home when they play. Click on the images above or here to see this product in my store.
