This is the first set of spiral reviews I use with my 4th grade students. It spirals ahead of the standard so students become familiar with solving word problems, finding factors and multiples, number forms, multiplicative comparisons, and more. As the PowerPoint slide progress, more standards are added (e.i. prime and composite as well as multiplication and division). 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 17 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.
