3tKteam has created a great math activity for you to do with your students during small group, centers, and/or math intervention time. This activity is also differentiated to meet the needs of all of your learners, from the students who need numbers 1-10 or those who can move on to 11-20. Students will count and pick the correct number from 3 options. Or you can challenge them even more by writing in the correct number. For extra durability, you may want to mount each card onto card stock or construction paper and then laminate.
