A set of double-digit subtraction dominoes to use in the classroom.
Use this teaching resource as a math center activity to encourage students to apply the split strategy when subtracting.
Print, cut out, and laminate a class set of the dominoes to store in a resealable bag. Alternatively, to reduce plastic use, print on cardstock.
Individually, or in small groups, students connect the dominoes by matching the answer with the question.
