![]() ![]() The folding and cutting activities are intended to help students understand that all parts must be equal in size when naming fractions. The lesson continues with an exploration of folding and cutting shapes to partition the shapes into halves, thirds, and fourths. This lesson begins with students discussing how to share a cookie with one other person, partitioning the cookie into halves so each person gets the same amount. ![]() This lesson involves partitioning shapes into equal parts, including halves, thirds, and fourths. Similarly, have students identify shapes that have not been partitioned into halves, thirds, and fourths because the parts are not equal in size.Įncourage students to find halves, thirds, and fourths of shapes, sets, and even groups of people, to help them become familiar with different representations of these unit fractions. Have students identify shapes that are partitioned into halves, thirds, and fourths. Give students additional examples of shapes to partition into halves, thirds, and fourths.ĭiscuss strategies for determining whether the parts are equal, and review vocabulary used to name the equal parts. Have students predict and draw cut lines to partition a cookie (circle) into two, three, and four equal parts for sharing. Make certain they are aware that not all folds will partition the whole into equal parts. Introduce students to equal parts of a whole, demonstrating this through the use of cutting paper and paper folding. Scaffolding, Active Engagement, Modeling, Explicit Instruction W: ![]()
