Rewriting fractions as decimals

We already know that the same quantity can be represented as a decimal or a fraction. In this tutorial, we'll begin to see how a fraction can be rewritten as a decimal. The trick is to make sure the fraction has been reduced or simplified as much as possible, then to convert the fraction so that you're dealing with tens or hundreds--a much friendlier environment for our decimal friends!

Measuring with metric and U.S. customary units: intro

The International System of Units used today is based on the metric system. The United States, however, likes to dance to a different drummer and still uses the old British Imperial System (U.S. customary system) for most of its measuring. This tutorial will introduce you to both for measuring distance, volume, weight and time. Common Core Standard: 4.MD.A.1

Unit conversion

When you first started measuring things in units in 2nd grade, you saw that you might want to use different units depending on the scale, application or culture that you are in. You can imagine that you'd want to convert from one unit to another when needed. Whether we're moving between metric and U.S. customary units, between ounces and pounds, or between meters and kilometers....these conversion examples and explanations are going to help a lot! Common Core Standard: 4.MD.A.1



Watch: Converting between units of time

Word problems: moving between units of measurement

Are we having fun yet? We are! Let's solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Common Core Standard: 4.MD.A.2
