Included are 6 center directions for chapter 4 Math in Focus. Print the center directions on color and laminate. Supplies needed include white boards or white paper to show work on, copies of the recording sheets, number cards, tiles and dice. Enjoy these fun centers for practicing subtracting larger numbers! Place each one at a center and divide the class into 6 groups. Have them rotate through each one, spending about 15 minutes at each! Check out all of my materials for third grade Math in Focus!
