Fractions - Unit and non unit fractions - Presentation

The lesson on unit and non-unit fractions provides a comprehensive understanding of these fundamental concepts in mathematics. A unit fraction is a fraction where the numerator is one, and the denominator is any positive integer, whereas a non-unit fraction has a numerator greater than one. Students are asked to give examples of each to solidify their understanding. The teaching slides guide students through various activities where they must identify and differentiate between unit and non-unit fractions. For instance, they are presented with shapes divided into equal parts with certain sections shaded, and they need to complete sentences that describe the fractions represented by the shaded areas. This visual approach helps students to grasp the concept that unit fractions have only one part shaded, while non-unit fractions have multiple parts shaded.

Further activities delve deeper into the comparison of these fractions. Students are encouraged to shade shapes and circle items according to given fractions, reinforcing their understanding of numerators and denominators. They explore fractions with the same denominator and discuss what is the same and what is different between them, such as comparing 1/3 to 2/3. The lesson also includes reasoning tasks where students must sort fractions into tables and determine whether statements about the shaded parts of shapes are true or false. These exercises not only teach the difference between unit and non-unit fractions but also develop critical thinking and reasoning skills in relation to fractions as a whole. The lesson concludes with a discussion that prompts students to articulate their understanding of unit and non-unit fractions and to observe the similarities and differences among various examples.
