Day 77: Math 6: Convert Customary Units - Math 6+: Challenge Day / Scale Drawing Project

Math 6 students began Lesson 5.8: Ratio Reasoning: Convert Customary Units. In this lesson, students worked with customary units of measure to learn two approaches to converting measurement units. Students were introduced to dimensional analysis which is modeled in the video posted below. This skill has been challenging in past years.

Math 6+ students worked to solve two problems below and then were introduced to a project that they'll have time to complete in class over the next several class periods. Here is a link to the resource that they were provided today in class: CLICK HERE.

November is the 11th month of the year. How do you tell if a number like 13,574 is

divisible by 11? Alternately, add and subtract the digits by computing:

1 - 3 + 5 - 7 + 4 = 0

Since 0 is divisible by 11, the original number of 13,574 is divisible by 11. 

What digit should replace the "a" in the number 1099a89 so the number is divisible by 11?

Standards addressed in today's lessons:

Math 6:

• Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. 
• Solve unit rate problems including those involving unit pricing and constant speed.
• Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
