In yesterday's post we looked at ratios and rates in real-world contexts and even learned about paying for college and how education levels affect salaries. If you missed the live stream with the answers and explanations, you can watch it here. Today we are still within Reporting Category 2, Computations and Algebraic Relationships, learning how to find a percent, whole, or a part given only two of the three pieces of information. We'll also look at how students can write problems to represent equations and inequalities.
Percents, Parts, and Wholes
In the sixth grade, students learn a natural extension of using ratios to find missing pieces of information. A common scenario is students being given a part and the percent while being asked to find the whole. Watch the video below for more information.
With that information fresh in your mind, try this problem from a released STAAR test.
In the same way, students might be given the part and the whole while being asked to find the percent. To learn more about that, watch the video below.
Finding a percent is a fairly straightforward process. Test yourself with this practice problem.
The only permutation of this standard that was not tested in 2017 is finding the part while being given the whole and the percent. If you want to learn more about that, you can do so here.
Writing Problems for Inequalities and Equations
Instead of simply solving word problems, students in 6th grade are now asked to write or match a problem situation with an equation or an inequality. Here's a short video explaining this math standard.
Now that you've watched the video above, you're ready to tackle the following problem.
Correct Answers Tonight (4/21/20) at 8:00 pm (CDT), I'll live stream from my YouTube channel to go over the answers to these three practice problems. Make sure you've already worked them out ahead of time. I can answer questions you might have in the stream chat and I'll put the recording on my channel and in this post for anyone that couldn't watch it live.
If you haven't done so already, you can subscribe to the channel and click the bell icon to get notifications for live streams and new videos that I post.
