Mastering the World of Fractions
A very solid introduction to fractions which utilizes the Master Fractions manipulative set. The workbook progresses from introducing the concept of fractions, beginning with the need to share food among friends, to adding fractions with common denominators. In between, it covers fractions from ½ to 1/20, parts of a group, comparing fractions, equivalent fractions, mixed numbers, improper fractions, and more. Like others in this series, it ends with real life applications. The Master Fraction manipulatives are small, square, spiral-bound booklets with template overlays instead of pages. The bottom, opaque layer is printed with two circles, a square, and a rectangle (wholes). Each overlay divides these forms into fractional parts. The Master Fraction2 has overlays for ½, ¼, 1/8, and 1/16. The Master Fraction3 has overlays for 1/3, 1/6, and 1/12. The Master Fraction5 has 1/5, 1/10, and 1/20 overlays. The back of each Master Fraction is printed with the decimal and percentage equivalents for fractions included in that set (i.e., the Master Fraction2 has equivalents for ¼ through 4/4, 1/8 through 8/8, 1/16 through 16/16). Equivalents for "2" in halves, fourths, eighths, and sixteenths are also shown. You can place templates from one set over those from another to compare fractions. You can also color in fractional parts on the overlays using dry erase markers. These manipulatives may be used with any activity books or as instructional tools without the workbook.
