Infintie and No Solutions

POW quiz tomorrow. Some extra practice can be found here. Most of these are harder than ours. 

Objective

Solve equations with infinite solutions

Homework

Finish yesterday's work if needed.

I am totally confused

The chart didn't have any "=" but it is easy to get hung up on the equations we have been doing. You just needed to change the x into the number for that row, then follow the order of operations.

I couldn't find the ___________ button. Some of our calculators have seen better days. Lots of people have pressed the "y=" button and the "(" ")" buttons so they can be hard to read. Luckily, there isn't a self-destruct so press button! "Clear" or " "2nd" then "Mode" will get you out of anything!  This is an image of the calculator if that helps.

What are we even doing?

Why are we doing this? So we can do this, which is very useful in many jobs you might do someday.

A Part (oops ParK) Ranger's Work STILL isn't done

Objective

Write and solve two step equations

Classwork/Homework

Tips:

1 and 2:  Re-read the problem like it says 2 (or another "friendlier" number) rather than 1 2/3.  What would you do then?  Redo this with the 1 2/3.

3: What did you do to the 10 and 15 in a and b?  Do that to the variable.

4: You might want to use my "friendlier number" trick to think of what to do.

5: Don't you have an expression that equals the number of feet that are left?

More Two Step Equations

POW

We started off knowing that Kimberly went to Sea World, Amanda didn't pay with cash, the person who went to Universal didn't use a credit card, and the person who paid with a gift certificate went to Disney. 

We used the things we knew to eliminate what couldn't be true which left us knowing that Universal was paid for with cash and Sea World was paid for with a credit card

We filled in what we figured out. 

We know from the other Payment Type boxes that Amanda didn't pay with cash so she couldn't be the one who went to Universal.

Fill in what was left. We have all the information we need now, but fill in the payment types just to make sure.

Classwork/Checking Homework

 Homework

Choose one from each pair to solve. 

I am lost.

The fractions confuse me, I want to get rid of them.

The fractions confuse me, but getting rid of them was worse. 

Fractions or just whole numbers, I don't know why you are adding when it says subtract or dividing when it says multiply.  I think there was another link for this yesterday. 

I don't remember how to work with the decimals.

Tomorrow

More of the same.

Homework

1st:  Finish Problem 1

2nd-7th: Problem 2

I am so confused.

How did we come up with the equation?

How did we solve the equation?

Tomorrow

Go over problem 2. Continue writing and solving two step equations.

Test Day!

Each question is worth 4 points. One point for the correct answer, one point for showing work, and two points for good reasoning. Scores will be calculated using the average score then converted to a "normal" grade.  So, if you read a problem wrong but did everything else right or only knew how to do part of the problem, you can still get a decent grade.  However, just marking the right answers won't get you a good grade. (If you did it right, you should want to show off how smart you are by telling how you did it!)  All kinds of thing count as reasoning: Drawing a picture, making a list, showing calculations, making a table, solving a similar problem with "friendlier" numbers", etc.



If you were absent there will be a form to fill out about when you can take the test in your clothes pin when you get back.

If you have first lunch then I will sign the form to use as a pass to get your lunch and come in my room to take the test.

If you have second lunch then you will have to talk to your elective teachers and see when they can let you come in to take it. Get them to sign the form and bring it with you when you come to take the test.

More info about the test will be posted after everyone takes it.

But I am lost!!!!

If factoring before multiplying is confusing, don't! You can simplify after. If you want to try it that way, Math.com has an explanation. 

There are tons of videos and activities dealing with multiplying fractions on Kahn Academy. 

Multiplying decimals too.

They even have dividing fractions and decimals. 

Math is Fun has a Multiplying fractions song.  I haven't looked there for the rest but I bet they have something.

BTW: Kids have shown me some of these sites, if you know of one I missed please comment!

But I don't understand any of it!

Try this or this if you don't understand the integers (negative numbers). You will need the info from the other side of your remind 101 paper.  Kahn Academy has one too, use the hints!

Try this if you don't understand how to get a common denominator.  You will need the info from the other side of your remind 101 paper. 

This video will walk you through the adding and getting the common denominator.
