Task# Measuring Cups

Illustrative MathematicsVaries

This task could form part of a classroom activity where students are encouraged to find as many different ways as possible to make different fractions such as and then share their methods. While measuring cups would be helpful to experiment with and explore the different possibilities of how to use the cups, students will need to use mathematics in order to calculate the precise amount of water left in any given cup. Part (c) of the question has been deliberately left vague. On the one hand, students might provide one other amount that Lucy can measure, such as 7/12 of a cup which they can make by combining 1/3 of a cup and 1/4 of a cup in the one cup container.
