This is a companion unit to my Fourth Grade Customary Measurement Conversion product. It can also stand alone. This product includes a conversion pre-test, formative assessment, and summative assessment. Answer Keys are included, and I have used a format that is very quick and easy to grade. There are pages that can be used in Interactive Notebooks, Math Journals, or Math Centers. The pages can also simply be copied and distributed on their own. I have included Problem Solving activities for each type of measurement (time, length, capacity, and weight). You also get individual conversion charts for each student to use while learning!
