In Thursday's post we looked at operations with integers and positive rational numbers. If you didn't catch the live stream with the answers last week, you can watch it here. Today we are diving something that will be with middle schoolers for years to come - ratios and rates. We'll also take a quick peek at one of the personal financial literacy standards.
Real-world Ratios and Rates
Unbeknownst to many 6th graders, ratios and rates are all around us. In 6th grade, they learn to recognize how ratios and rates are used in the real world. Watch this video for an explanation.
With that under your belt, try to solve these problems from a released STAAR test. The second one was a griddable response question, which means it did not provide four answer choices to select from.
Representing Ratios and Rates
Ratios and rates do not always show up in the traditional format that uses either a colon (:) or fractional notation. Sometimes rates appear as simple multiplication scenarios. Watch the video below for some examples.
With that information, now you can solve this problem.
Personal Financial Literacy - College and Earning Levels
As a part of the personal financial literacy standards, students are expected to learn about the different ways to pay for college and the earning potential of graduates with various levels of education. Watch this video for a quick summary.
Even though college is still quite a ways off for 6th graders, it's never to early to start planning!
Correct Answers Tonight (4/20/20) at 8:00 pm (CDT), I'll live stream from my YouTube channel to go over the answers to these four 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.
