This is the 5th set of spiral reviews I use with my 4th grade students (I normally use this during the end of the 3rd 9 weeks). It spirals symmetry, problem solving, angles (types and possible measures), adding and subtracting large numbers, decomposing fractions/equivalent decomposed fractions, multiplying fractions and whole numbers, numbers in the base 10 system, as well as number and shape patterns. 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.
