**EXTRA CREDIT click HERE** Due Friday, 2/15! Greetings! Last week students did a great job learning some new concepts dealing with percents. During review of Lesson 6 - Fluency with Percents, students created posters showing their work for various real-world problems (see below)...Students solved these problems using a variety of strategies including double number lines, the formula part = percent * whole and proportions. We also covered percent increase and decrease, markup and markdowns and percent error. This week we will review some key concepts learned last week and talk about simple interest as well as taxes, commissions and fees. This will bring us to the end of Mid Mod 4 and we will most likely be looking at a test on Friday. Here are some review links for various topics that we have covered recently. Percent Error - in class, we talked about how this can help put things in perspective instead of just relating the amount by which a value was off. For example, if you were to measure the length of a football field and were a centimeter off, versus a heart surgeon who was a centimeter off, the percent error of the heart surgeon would be much larger, given that he/she has less room for error. The person measuring the football field would have a low percent error because what they are measuring is relatively large. The larger the actual value (the denominator in the percent error calculation), the more you can be "off" from the exact value and still have a relatively low percent error. Percent Increase/Decrease This week's Quizizz will be a review of percents. Code is 826982. As always, quizzes are due by Thursday night. Upcoming Key Dates:
