TLI FAQ

Remember, the TLI test today was a PRE-test. It is ok if there was something you had not seen before the test. I didn't help anyone because I wanted to see what you knew and what kind of reasoning/test taking skills you have. We will get to everything on the test some time this year. I will cover it in detail then. For now, here's a quick run down of the "weirdest" stuff.

How do I put ___ power in the calculator?

There's a button that looks like this ^ called the carrot. 10 to the 4 power is typed 10^4. Or you could type it 10*10*10*10.

What is scientific notation?

Scientific notation is a way to write very large or very small numbers in shorter way.

157,000,000,000,000,000,000,000 is 1.57*10^23 in scientific notation.

0.000000000000000000023 is 2.3*10^-20 in scientific notation.

What is this symbol?

 is a radical. It means to take the square root of the number. That is like the opposite of squaring it.  √25 =5 because 5² is 25. 

 is a cubed root. It is the opposite of cubing a number.

TLI Testing

This is a PRE-test over many skills for bonus points. It has 20 questions and an Open Response. Most of the questions have an old skill being used differently. They aren't easy but can be figured out if you stretch. This test can only make your grade better, so do your best but don't worry too much.

Each question is worth 2 bonus points.

Because this test is given on scantron pages, it must be done in pencil. No points will be awarded for tests done in pen.

This video walks through the steps to find rate of change, answers very common questions ("What if I choose the wrong points?", "How do I decide which points?", "How do we all have the same rate of change when we used different points?") and does a preview of something that we will get to very soon.

Classwork/Homework FAQ

Does it matter which numbers I put on the x-axis and y-axis?

YES!!!!!!!!!  

Why?

That is a tough question! Sometimes we accept a practice so it's easier to communicate to others. It is a little like spelling. Even though we would say "phish" the same way as "fish" we still spell it the second way to make it easier to understand. This is one of those things.

If you find a better explanation, I would love to see it.

Is the x the input or output? 

Check the graph on page 74.

What does the first number 3 mean?

Which bubble does the first number come from? What does that bubble represent? (It might feel like it was too obvious to be correct.)
