Use these cards for quick, fun practice adding and subtracting 1, 10, or 100 to three-digit numbers. There are 24 cards in this set. Pass the cards out to students (Some students may need to share cards or have more than one card). The student with the card stating, “I will start” reads his card first. Whoever has the answer to that card reads the answer on his card and then reads his question. Students continue until all cards have been read. Time students, and have them try to beat their time.

This file contains 60 cards for matching activities. The cards have numbers in expanded form, standard form, etc. Students have to match the 3-digit numbers up with their correct forms.

Students work to match up the expanded form with the standard form of the number. 2. Silent Match Up ? Pass out one car
