How are your rounding skills?
This week we begin our Sales Tax lesson…and you MUST be able to round to the nearest cent. Start refreshing this skill by trying out the game Scooter Quest by Sheppard Software
Here is the 3rd example of using the percent proportion: determining what percent a number is. View this a few times to help reinforce the concept while you are completing your homework. As always, let me know if you need any extra help!
Here is example #2 of how to solve using the Percent Proportion
We are starting to learn the Percent Proportion in class. Here is a video that reviews how to set up these types of problems.
Remember:
- The % is written as a fraction with a denominator of 100
- IS over OF is the easiest way to recall which number goes where in the proportion.
- Cross multiply & then divide to determine the value of the variable
Make sure you take a look at this video to help you recall the steps we learned in math. See me if you need extra help =)
I Know That….cells
One of the best sites I’ve come across lately for cell review is I Know That. They have a kid-friendly plant & animal cell review activity that also reads each of the organelle names. You can also look at cells under a microscope to give you a chance to see “real life cells”. I highly suggest you visit this site!
Super Scale of the Universe (and cells!)
My students loved this Scale of the Universe interactive I showed them when we were learning about cells. It really helped put the size of organelles into perspective with other objects for them….very visual! Today, I was put on to the latest scale project…this time the interactive was created by 14yr old twin boys! Read more about them here
You can check out the original mock up of their scale here. Their latest version below is MUCH more detailed & eye-catching! So have fun scrolling from left to right to zoom in or out and relate the objects size & space to those around them…..pretty cool!!
Do you remember how to find the % of a number? Check out this really great video that reviews all of the basics and even reviews how to convert percent to a decimal….excellent!
Do you know the difference between plant & animal cells? Sheppard Software offers tutorials, games & quizzes to help you compare & contrast these cells. Give them a look!
Inside the Cell
One of the best sites for all things cells is The University of Utah’s Genetic Science Learning Center aka Learn.Genetics. They offer an in-depth look inside the cell. The organelles, quick animations detailing the functions of each, as well as a great interactive to help you review all of the organelles. It’s a great resource to help you review for a quiz!
The Cell Theory
Check out this great interactive from The Children’s Museum of Indianapolis. It focuses on the Cell Theory, prokaryotic & eukaryotic cells & plant and animal cells….nice & simple but complete.
Need a refresher on how to write a fraction as a percent? Remember you can cross multiply! Check out this video from the website Yourteacher.com
