I have created 3 sets of cards for your students’ fun! Deck A has the numbers 0-20. Deck B and Deck C have numbers between 0 and 75. This is a great mental math warm-up for your class. Deck A was made for 21 students but I have adapted it so you can play this game between 17 and 21 players. Deck B and Deck C was made for 30 students but I have adapted it so you can play this game between 17 and 30 players. I have included lists of cards you need for the amount of students you have starting with 17 students all the way up to 30 students.
