Fractions - Non-unit fractions - Presentation

In a comprehensive series of teaching slides aimed at mastering fractions, today's lesson zeroes in on non-unit fractions. A non-unit fraction is defined as a fraction where the numerator, the top number, is greater than one, unlike a unit fraction which always has one as the numerator. Students are encouraged to think about what non-unit fractions are and to provide three examples to solidify their understanding. The term 'non-unit fraction' is a key point of discussion, setting the stage for the activities that follow.

The lesson includes various activities that help students practice identifying non-unit fractions. In the first activity, students are presented with diagrams where certain portions are shaded, and they must determine the fraction represented by the shaded area. These fractions include examples like 2/3 and 3/4, among others. Subsequent activities require students to shade specific non-unit fractions of shapes, such as two-thirds or three-quarters, reinforcing their grasp of the concept. Reasoning exercises challenge students to identify and correct mistakes in fraction representation, such as misconceptions about the roles of numerators and denominators. The lesson culminates with independent work where students sort fractions into categories, identify errors in fraction representation, and engage in discussions about the composition of wholes using quarters and thirds, further exploring the relationship between numerators, denominators, unit fractions, and non-unit fractions.
