Fractions on a Line Plot

Illustrative MathematicsVaries

The purpose of this task is for students to add unit fractions with unlike denominators and solve addition and subtraction problems involving fractions that have more than one possible solution. The reason that students are asked to record their results on a line plot is that they need a way to systematically record their sums and to help them reason about the possible sums they can make with the cards. While this task does not ask students to record measurement data, it is a good introductory activity for working with line plots with non-whole numbers. This activity would be best during the early months of 5th grade when students are gaining familiarity with adding and subtracting unlike fractions and strengthening their understanding of equivalency on the number line.
