Unit 2 6th Grade Math Videos

Sunday, December 24, 2017

The videos in this video align with the state of Georgia Math Standards.
Here are the standards that are provided on the state website.
"Understand ratio concepts and use ratio reasoning to solve problems.

MGSE6.RP.1 Understand the concept of a ratio and use ratio language to describe a ratio
relationship between two quantities.

MGSE6.RP.2 Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0 (b
not equal to zero), and use rate language in the context of a ratio relationship.

MGSE6.RP.3 Use ratio and rate reasoning to solve real-world and mathematical problems
utilizing strategies such as tables of equivalent ratios, tape diagrams (bar models), double
number line diagrams, and/or equations.

MGSE6.RP.3a Make tables of equivalent ratios relating quantities with whole number
measurements, find missing values in tables, and plot the pairs of values on the coordinate plane.
Use tables to compare ratios.

MGSE6.RP.3b Solve unit rate problems including those involving unit pricing and constant
speed.

MGSE6.RP.3c Find a percent of a quantity as a rate per 100 (e.g. 30% of a quantity means
30/100 times the quantity); given a percent, solve problems involving finding the whole given a
part and the part given the whole.

MGSE6.RP.3d Given a conversion factor, use ratio reasoning to convert measurement units
within one system of measurement and between two systems of measurements (customary and
metric); manipulate and transform units appropriately when multiplying or dividing quantities.
For example, given 1 in. = 2.54 cm, how many centimeters are in 6 inches?"

Take the guesswork out of Unit Conversion-Convert meters to feet

Tuesday, December 22, 2015

In this video you will learn how to convert from meters to feet and meters to inches.
The strategy taught in the video will allow you to convert any unit of measure.

Step 1. Place your given unit of measure over 1
Step 2. Write a multiplication sign
Step 3. Place the unit you want to convert to on top of another fraction
Step 4. Place the unit you are given on the bottom.
Step 5. Ask " which is larger, and pace a 1 next to the larger unit
Step 6. Cancel units and multiply the fractions.

Confused, the video works three examples for you.

Unit Conversion-Math Help

Thursday, November 19, 2015
If you are able to run 5 kilometers in an hour, what is this pace in miles an hour? This would be an example of a unit conversion. A problem like this could also be called a dimensional analysis problem. A unit conversion problem can be solved by setting up a ratio or proportion, cancellingunits and then multiplying two fractions.

These three videos will help you how to set these proportions up, and solve.

Video one is a starter video. The sample problems only involve making one conversion.
For example, 345 ft/min = _______ ft/hr


Video Two solves unit conversion problems in which two conversions are needed in order to reach your goal. These problems can be confusing,however,after watching several example problems you will realize it is really not that difficult.



Finally, this third video uses boxes, and different colors while setting up a unit conversion problem. This method helps you organize, and solve a unit conversion problem. If you get confused on how to set up a unit conversion problem, this video will help.

Top 10 YouTube Unit Conversion Videos

Tuesday, November 17, 2015
Imagine you just went to the track, and ran 1600 hundred meters in your fastest time ever. You now would like to know what this time converts to if you ran a mile. This would involve converting from meters to miles. You encounter these type conversions in chemistry, math, cooking, track, and many other places in life.
After looking at countless conversion videos on YouTube I have composed a list of the top 10 conversion videos found on YouTube.


This video bills itself as " "The most entertaining unit conversion video ever made!"  It does have nice music, but the strength of the video is that it provides a system for solving unit conversions.


This video takes a different approach to unit conversions, and tries to help the viewer understand how, and why we convert. The instructor gives very clear instructions, and I found it really helpful.



This video has very clear directions, and focuses on converting length. The video works sample problems converting from inches to centimeters, and other conversions involving length.



This video on unit conversion is very well done. It starts off with an overview of the different types of units, and why we convert. It then gives directions on how to convert.  It also gives an overview of significant figures, and why it is important to conversions. If you like any Crash Course videos you will enjoy this one.



This video is produced by East Tennessee State University. I felt it did a great job giving very clear directions on how to convert. The video converts both distance, and time. If you listen carefully you can hear a Tennessee accent, and I also liked it because my father graduated from there over fifty five years ago.


I included this video on conversion because the conversions in this video involve three or four steps. For instance, one example is converting from years to seconds. This video is helpful if your conversions are a little more involved.


This video is by Khan Academy, and is like all other Khan videos,it is clear, and very helpful.


This is a measurement rap. It is fun, and focuses on the different measurements, and therir values. I promise, it is fun.



This a basic video, but solves word problems using unit conversions. Just when you thought you understood unit conversions they throw a word problem at you. This video will help.



This video is geared more for middle school students who are trying to learn dimensional analysis. It solves two problems that only involve a one step conversion.

Check back often. I create a top 10 YouTube list every other day, and upload a new Math video everyday.
