Translating Verbal Phrases into Algebraic Expressions



I'm a little behind in recording my INB activities.  Wow, the first two weeks of school have been a whirlwind.  I finally started to get a little caught up yesterday since I gave long quizzes and was able to organize the piles of paper that were EVERYWHERE. 

This INB activity is actually one I did the first week of school.  Our first lesson in Algebra I is on Translating Verbal Phrases.  We then extend this lesson on the next day by learning how to take a verbal phrase like "The set of y-values are three less than twice the x-value" and create function rules, mappings, tables, and graphs.

The lesson went well, it was short enough to keep their attention and then the INB activity allowed them to practice in a hands on way.  I then assigned a puzzle page  for homework that had a corny joke at the top.  When I handed it out, I was surprised to hear kids say things like, "I love these things".

Here are the files if you'd like to download them.  One thing I have found about cut and paste activities.  Give the students the page that they have to cut out first and give them about three or four minutes to get started cutting.  By then almost everyone will be done or almost done cutting.  Then pass out the "answer mats".  If you don't do this, some just want to write the answers down on the mat and skip the whole cutting part.  This may sound strange, but I think the whole act of cutting and pasting the answers seems to make the material stick in the brain better than just trying to write down the answers as quick as you can and get it turned down.  It is a deliberate effort on my part to get them to slow down and THINK.

Oh my! Love this.
I am a first year teacher this year teaching Algebra I to at risk students.
We didn't start school until after Labor Day, and we the whole first week was some basic prealgebra skills (fraction operations and integer rules). I just taught verbal expressions on friday.
I will follow up with this lesson for sure!

Great Job! Thanks for posting and allowing us to use. What are the three expressions that use parenthesis on the second page of the lesson?

@anonymous, the three phrases requiring parentheses are:
1. Times the sum of

2. Times the difference of

3. Twice the sum/difference
