This game is great for improving addition fluency for numbers 1-20. Students in first grade need to be able to add and subtract fluently within 20. This I have who has game has been made to help student become more comfortable with their math facts in the form of a game. I have used this as a whole class, but also in centers. This set includes visuals for the students to count to help them with the addition.
For durability I recommend printing them on cardstock and laminating them.
