knaidel re: Solving Two Step Equations with a Do/Undo chart
Love the worksheet, would love it even more with an explanation of how it is used. I get the idea and really like the concept but could use some tips re. how you introduce this to students.
June 10, 2013
Shawna H  (TpT Seller)
When students are solving two-step equations for the first time, they are often unclear on which number to “undo” first. I’ve tried a variety of tricks, but the do/undo chart works very well for many of the kids. They use the scaffold for a couple days, and then they are able to do the same steps in their heads. What I like about the do/undo chart is that it connects solving equations to the Order of Operations.
This is one way to present it:
1. Start off by reviewing order of operations with various problems. Then, write a problem on the board, like 15(3) + 9 = 54. Ask if it is true or false, and to explain the steps of proving that it is true (multiply 15 times three first, then add 9, which does in fact equal 54).

2. Then, write the equation 12x + 8 = 92. Highlight the variable. Discuss whether or not they can use order of operations to solve it (they can’t because they can’t multiply first, because they don’t know the value of x).

3. I explain that when there is a variable in an equation, you can’t follow the order of operations, so we have to treat it more like a mystery. I emphasize that we have to “undo” everything that should be done (or has been done to the variable). It’s a mystery…we’re finding an unknown, so we have to work backwards to discover what the variable’s solution is.

4. I introduce the DO/UNDO T-chart. I say that it is just a tool that helps us keep track of how to undo the equation which solves the mystery. I tell them that we’ll only use it for a day or two, and that after that it’s optional. We’re still using the 12x + 8 = 92 equation.

5. Starting on the DO side, I ask, “If we could, what would we DO first in the equation (using order of operations). “ Or, another way I’ve presented it is “What has been done to the variable?” The answer is “multiply by 12), which is what I write in the chart under the DO part. x12

6. I ask, “What would be done next?” or… “What has been done to the variable next?” The answer is ADD 8. I write that in the chart under x12.

7. Now that we have written the two steps in the DO side, I explain that we can solve the mystery by UNDOING these steps. I tell them to put their pencils on the Star…because that is where they need to STARt. They look at the DO side, which says +8. I ask how to undo it, and they say -8, which we write down. That is the first step to solve the equation, so I have them do that step on the actual equation. They subtract 8 from both sides (which they already know from solving one-step equations). Then we move to the next DO/UNDO step. Since it says x12 in the DO side, then need to write /12 in the UNDO side, and then divide by 12 on both sides of the equation. They are left with x = 7, which is the solution.

So, the DO/UNDO chart helps students identify what has been done to the variable, and how to undo it. It helps to explain to them that solving an equation is using Order of operations backwards, because we’re undoing a problem…solving a mystery. It also helps if they know that the order of the steps matters. If they had divided by 12 first, and then subtracted 8, they would have gotten an incorrect answer. The chart helps them know which step to do first until it becomes more automatic.

Finally, it’s good to give them equations with simple math, but also harder math. If all the equations are too simple, they hate having to show their steps. One year I gave them really difficult numbers (big numbers or with decimals) but let them use calculators to do the calculations as long as they showed their steps. It worked well…they were so happy that they didn’t have to do the math, they were willing to show their steps. They also couldn’t use mental math to solve the problem before they started.

How long does it usually take your class to complete?

Shawna H  (TpT Seller)
I gave them two class periods for their rough draft, and then it was homework due the next day. I told them they could ask me process questions, but all content had to be found from their math notes, or from talking to peers. There were some GREAT discussions when they can work together/near each other. It really promoted vocabulary. On day 3, they did peer review/edit. Then I gave them 5 nights (over a weekend) for the final project (no time in class).

Englishr re: Sold
Hi there, I just tried to place an order of 16 of your Sold books, but am having a problem. I could not press a quantity button for 16, so I pressed the order button 16 individual times! The problem is that the shipping came to \$40.00! Could you please assist?
Thanks,
Rebecca English

I relisted it as a bundle, so it says 1 item for \$47.40, but that includes all 16 books (the price reflects the 15% discount that I offered on the day you tried to purchase it). I have changed shipping to be \$15.00 USPS priority mail, but I can also reduce the price to \$10 if you don't mind Media Mail. Just let me know. I hope I was able to get back to you soon enough!

I don't really have an answer key for that activity because the answers vary on a couple of the problems. I know I kept a copy of one of my student's worksheets; I can scan it into my computer and email it to you if you'd like. I wouldn't be able to do it until Monday the 7th.

How do I order all of them?
April 10, 2012
Shawna H  (TpT Seller)
Gosh, I'm not exactly sure. I know I have 15 for sale on this site, but it looks like you can only add one at a time. Have you tried to add more than one to your cart? Maybe you can add all 15, but you need to do it one at a time? I will lower the shipping rate to \$2.50 per book, so the total price per book will be \$6.00, which seems to beat Amazon's price. If that doesn't work, email me at hodovance@gmail.com, and we can figure out how to get them all shipped to you.

How many Sold books do you currently have? I'm going to be teaching a multi-cultural literature class for at-risk high school students.
Are there any other classroom sets/titles that you may have?

I believe I still have 16 copies of the book, although it might be 15. I could double check tomorrow. I don't have any other novels that I'm selling right now. Thanks.

How did you color the complementary angles on the "understanding angles" worksheet?
September 22, 2010
Shawna H  (TpT Seller)
Hi there,
If I recall, I believe I had them do some rainbow-style layering...so there was a lot of color because there are so many angles that are complementary.

Gail Neufeld re: Understanding Angles: A Coloring Activity!
I can't tell if my message went through: I love the idea of your worksheet. It would be improved if it had a title. Is that something you can add?

Hi there,
I just resaved it as a Word 2007 document, so you can add/revise your own title. I also added a quick one. Thanks.
