**4**^{th}** Grade Homework 4**^{th}** Quarter**
This quarter, you will be in charge of what you do each night. As always, there are videos to watch (if needed) and starred activities to practice. You must do all the starred activities and strive for 5 in a row correct. Remember to go to the mastery challenge in order to master the concept (dark blue). The videos are a resource. Watch as few or as many times as needed. Be sure to complete the Khan menu by the end of the quarter.. The remainder of quarter will be posted later in the month. If you complete this section, go back and master other 4^{th} grade concepts from earlier in the year.
**Decimals and fractions**
Decimals and fractions are two different ways of representing the same number. In this tutorial, we'll explore converting between the two and thinking about what exactly decimals represent. Common Core Standards: 4.NF.C.5, 4.NF.C.6, 4.NF.C.7

**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
Watch: Metric system: units of distance
Watch: Metric system: units of volume
Watch: Metric system: units of weight
Watch: U.S. customary units: distance
Watch: U.S. customary units: weight
Watch: U.S. customary units: fluid volume
Watch: Finding reasonable unit of measurement example
Watch: Choose pounds or ounces to measure weight
Do: Unit sense
**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
Watch: Converting U.S. customary units of distance: feet to inches
Watch: Converting metric units of distance: kilometers, meters, centimeters
Watch: Converting U.S. customary units of fluid volume
Watch: Converting metric and U.S. customary units of weight
Do: Converting to smaller units
**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
Watch: Units of measurement word problem: time to leave for home
Watch: Units of measurement word problem: time
Do: Time word problems
Watch: Units of measurement word problem: making change
