These two resources will help students be able to use tally marks!
The first one is a poster of the numbers 1 - 10 with their tally mark representations. The poster can be copied and cut apart to make a matching game or flash cards.
The second is clip cards for students to practice. Simply laminate, cut out and have students use clothes pins with them. They can be used in small groups to reteach and reinforce or in a center.
