This summer, I had the pleasure of attending the Idaho Regional Mathematics Conference in Boise, Idaho. I loved all of the classes and found Phil Daro (lead author of the Common Core Standards for Math) to be quite interesting. One of my favorite classes was, The Three Read Strategy and the Bar Model presented by Sarah Reynolds, a local instructional coach. Sarah has given me permission to share her presentation with you today!
Three Read Strategy and the Bar Model Presentation:
When we read it three times, our objectives are to:
•Clarify unknown vocabulary.
•Find things you did not find before.
•Make sense of the problem.
•Eliminate monkey thoughts.
Using the Three Read Strategy with a Math Story Problem:
The other day my student and I read this math problem together using the three read strategy.
After the first read, I asked, “Are there any any words you are not sure what they mean?” There wasn't, so we moved back into the problem and underlined the parts we thought were needed for the problem (see highlighted yellow).
Then we did our second read to try to make sense of the problem. “Is there any information in the problem that is not important?” (making sense of the context) My student thought that the detail about leaving on April 15th wasn't important or the 500-mile road trip part. He crossed those out. (see crossed out info)
Upon the third reread, we identified what math operations needed to be used. Then we think more about the problem. My student said that he didn't think $75 for the total 500 mile trip (realizing that the 500 mile bit of information was important) was realistic and that $75 would probably only get you about 300 miles if we used today's gas prices. He was so right! Two tanks of gas were needed for this 500 mile trip. The problem hadn't specified if the $75 was per day or for the entire trip.
I love when my students can reason and use logic in their mathematics. I encouraged him to be brave in class if he thought differently than what everyone was thinking and to share. It's part of having a mathematical discussion.
This method has also worked well for my younger students who are more prone to monkey thoughts. When they read a problem like this, they would be distracted by thoughts about their last family vacation. An ESL student may get stuck on the name Darryl. All good things to discuss after the first reading to get those thoughts out and move forward with the math.
How do you teach contextual math problems?
