I created this game board because my students absolutely love using playing cards in math. To play, students simply place two playing cards on the mat. Then they find the number that is 10 more/10 less than the number they made with the playing cards.
In my classroom, I copied this on card stock and laminated them for durability. This also allows the students to write and wipe them off with dry-erase marker.
I hope your students love this simple game as much as mine do. Happy Teaching!
