This is a series of worksheets to review customary and metric capacity measurement. Each worksheet has students make conversions within a system, and estimate the appropriate unit of weight measurement for objects in their lives. Designed to be done periodically after students have been taught a short unit on capacity. Excellent real world application of number sense, multiplication and division concepts. Great for integrating math with science activities! All questions tied to Common Core standards. Appropriate intervention for students that need additional review and support. Worksheets can also be used as mini-assessments. Also includes a blank page so teachers can continue to create more worksheets if students need more practice.
