Description
This is a complete lesson for learning how to convert units as a form of ratio reasoning. These are simple conversions, meaning that the “ones units” are whole numbers. For example, students may have to convert "three feet" to inches, but they will not have to convert "three feet four inches." I present more complex conversions in Lesson 2.
Pounds and ounces are both units of mass, and a ratio of 1:16 exists between the two. In other words, one pound is the same as 16 ounces. That means, for example, that something with a mass of three pounds also has a mass of 48 ounces. Once you know the ratio between two units of measurement of the same thing, you can convert units by multiplying. Suppose you bought a pizza with 32 ounces of toppings. How many pounds is that? We will multiply
32 ounces ∗ 1 pound/16 ounces = 2 pounds
The “ounces” cancel out, so 32 ounces = 2 pounds.
This lesson includes a set of Guided Notes for understanding how to solve these types of problems, an online check-in using Google Forms, a worksheet, and two enrichment tools: a set of flash cards usable for many different games and activities. The other is a Right or Wrong activity with 30 different conversion ratios – half right, half wrong!
The worksheet can be used for in-class practice or for homework. I recommend using the Guided Notes first to show students how to use conversion ratios. The students can then use Check In 1, the worksheet, the flash cards and the Right or Wrong to practice. For the Guided Notes, the students will use copies without the terms filled in, and you can teach using the Answers/Completed Work document.
All resources except the check in and flash cards can be used as printouts or online through Google Classroom. The check in is only online and the flash cards are print.
If you like this lesson, please consider my other 6th grade lessons covering all aspects of Common Core standards for Grade 6 math.
