These Giant Magnetic Fraction Circles enable the child to demonstrate fractions, percentages and equivalencies in an engaging hands-on way.
1 In Stock

Use this set for demonstration on any magnetic receptive surface such as a whiteboard or chalkboard, and provide students with a concrete model as they learn about fractional relationships. Take time to explain the percentage representation on the fraction circles to enrich students’ understanding of fractions. \n \nFor further hands-on explorations, have students use the Rainbow Fraction® Deluxe Circles (LER 0617) when teaching lessons and activities. \n

Sample Activities for the Giant magnetic Fraction Circles


Exploring Equivalencies

\nDisplay 1/2 using the magnetic pieces. Ask students to identify the piece. Ask, “Are there other pieces the same size as 1 /2? How can you find out?” Discuss ways of finding equivalent parts, including placing pieces side by side of others to compare. Give students time to handle the magnetic pieces to find other fractional representations for 1 /2. Ask students to record their findings on a piece of paper or in a math journal. You can extend this activity by asking students to find equivalent fractions for other amounts such as 6 /8, 2 /6, and 2 /3. \n

Fractions and Percentages

\nDisplay some of the magnetic pieces showing percentages. Guide students to understand that a fraction can be expressed as a percentage by converting the fraction to a decimal number, then multiplying by 100 to obtain a percentage (since percent means per 100). For example, 1 /2 = 0.5 = 50%. Place one fraction piece on the whiteboard and ask students to compute the percentage. Flip the fraction piece over to check answers. \nNote: Store the magnets flat to prevent from warping. If the magnets do curl, gently bend them back in the opposite direction to flatten, or rub them on the board and let them sit.
