A Very Rational Math Unit

Happy November to all,

We are right in the middle of our rational numbers unit and I'd like to provide a quick update.  Lessons so far have included multiplying and dividing negative integers, fractions, and decimals. We've also thrown percents into the mix. It's a gumbo of different types of numbers, each with its own set of algorithms for computation. This can be challenging for those who may not remember the "basics" of, for example, adding fractions or multiplying decimals. Toss in some word problems on top of all of this and you have quite the blend of math exercises! We have been working in class on all of this, of course, and will take our first quiz in the unit this Thursday, November 5. Please note report cards go home on November 16.

I continue to utilize Khan Academy for homework. The site is great, but can be a little confusing at first. Please check out this step-by-step guide if you and/or your child are having trouble finding the assigned sets or checking on progress: Khan Academy Tutorial

Looking forward, we will focus on adding and subtracting rational numbers. We will continue to practice the computation as well as use strategies to decode word problems. As always, I'm available for extra help on Tuesdays and Thursdays after school.

What you can do at home: Next time you are out to eat at a restaurant with your child, let them figure out the tip! As part of our discussion on percents, we discussed mental math strategies and used tipping as an example of real-world percent and mental math use. Students should be able to find 20% of a dollar amount. Giving them the opportunity to practice this in an actual restaurant would be wonderful.

Thanks for reading and thanks for your support at home,
Ms. Vila
