 The Master Fraction®
The Master Fraction®, with their transparent overlays makes fractions easy to see and understand. Students of all ages quickly grasp the concepts of equivalency, reducing, improper, proper, adding, subtracting common and uncommon denominators, mixed numbers, and more! The geometric shapes, bright colors, and "easy turn" overlays make this a favorite of teachers and students alike. The Master Fraction is an outgrowth of a teacher's prayer. Frustrated because the lines on standard rulers confused her students, and unable to find anything suitable on the market, she prayed and asked The Lord for help. In a dream she saw the math tool, "The Master Ruler", which is now being used by people everywhere. |
