This is the 6th set of spiral reviews I use with my 4th grade students (I normally use this during the beginning of the 4th 9 weeks). It spirals division, money, multiplication, shapes, area and perimeter, problem solving, and time. This colorful spiral can easily be printed 2 to a page for students to work out as a hard copy. Could be used whole group or as a center. This set includes 8 slides. I also have a bundle of these math spirals with 80 slides (8 different sets of spirals with all different standards) - purchased individually these spirals would be $40.50, bundled the price will be $34.00.
