4. The Math Forum @ Drexel - mathforum.org Notice/Wonder in Your Classroom  Help all students engage comfortably so that they are able to communicate their mathematical reasoning.  Students who would race to finish the problem, slow down, while students who would give up immediately have something that hooks them in.

10. If you get stuck, you might try to notice The quantities (known or unknown counts or measurements). Relationships between quantities. Information that is not given in the problem but that might be related or that the problem reminds you of. Key words from the problem. Your wonderings may include: I wonder what will happen if … I wonder what this word means … I wonder if this pattern will continue … What does this mean? What do they want? Does it have to be that way? Do I need to figure that out? How does this situation work? Is there another way to think of it? How will I know if this is true? What is a good way to express that? When is this true?

12. Adopting Notice/Wonder as a Classroom Practice  personal white boards  textbook “Given” as notice “Strategy” as wonder  a bridge to algebra

14. The Math Forum @ Drexel - mathforum.org MP1 Make sense of problems and persevere in solving them. Connecting to CCSSM  Do students write IDK on their papers?  Do students only focus on answers?  Do “expert” students say I’m done, now what?

15. The Math Forum @ Drexel - mathforum.org MP3 Construct viable arguments and critique the reasoning of others.  What does this mean in your classroom?  What do you do to develop this practice?  What’s one challenge you have?

19. The Math Forum @ Drexel - mathforum.org Notice/Wonder initially helps students to “make sense of problems and persevere in solving.” But that’s just the beginning. Once students are comfortable with the Notice/Wonder strategy, there are many more to introduce.

20. The Math Forum @ Drexel - mathforum.org Change the Representation  draw a picture  act the problem out  build a model  represent the problem using blocks, counters, etc.  represent the problem using a number line or lines  make a graph or graphs  organize quantities in a table  write relationships as equations  tell a different story

22. Student Thinking 1: I represented the problem visually with a fraction bar: I started with a bar that represented the total number of pets. I divided the bar into halves and made one half the fraction of cats. I divided the remaining half into two fourths and made one fourth the fraction of dogs. I divided the remaining fourth into two eighths and made one of them the fraction of horses. I divided the remaining eighth into two sixteenths and made one of them the fraction of birds. I divided the remaining sixteenth into two thirty-seconds and made one of them the fraction of birds. I was left with 1/32. There were no more pets left other than the gerbils. So the gerbils represent 1/32 of the total.

23. The Math Forum @ Drexel - mathforum.org Student Thinking 2: One way fractions are represented is by groups of things in a set. I don't know how many pieces of the set are gerbils, and I don't know how big the whole set is, and I don’t know how many pets each piece represents. Birds are the smallest part of the set so far, with 1/32 of the set. So it makes sense to me to start out with 32 pieces in my set. I drew 32 circles, and then for each animal, I filled in the number of circles represented by that animal with counters.

25. Student Thinking 3: I am going to represent the problem using an equation. I know: total number of pets = sum of all types of pets in contest. If I call the total number of pets P then I can represent the number of each type of pet as its fraction times P. This means:

26. The Math Forum @ Drexel - mathforum.org Get Unstuck When we don’t see how to solve a problem, we try to forget about solving the problem for now. All we want is to get our brain in gear. We ask ourselves these three questions: 1.What is going on in this problem? 2.What can I try? 3.What does this remind me of?

28. Student Thinking 1: I tried to use pictures to show how many people got on the train. I didn’t know how many people got on at Monkey House, so I drew a box. Then for each person I knew I made a dot. I made each stop a different color. At each stop there are three more people than at the stop before, so you have to draw what you had from the stop before and then draw three more dots. I don’t know what number goes in the ? boxes though, so I can’t add them up. Maybe guess and check will help.

29. The Math Forum @ Drexel - mathforum.org Student Thinking 2: At first I thought I had solved the problem really easily. First someone got on at the Monkey House. Then 3 more people got on at the Alligator Pond than at the Monkey House, so that means 4 people got on at the Alligator Pond. At each stop three more people got on than got on at the stop before, so I made a table to show how many people got on. Now I’m worried I made a mistake, because 20 people are supposed to get on at Big Cats, but I only have 16. Is Big Cats supposed to be part of the pattern? Student 2 asks Student 3, “Can I talk it through with you?”

30. The Math Forum @ Drexel - mathforum.org Dialogue Student 3: Sure. How did you know how many people got on at each stop. Student 2: Well first it said the first passenger got on at Monkey House. Student 3: I thought it said “passengers.” Student 2: Oh, you’re right! It must be more than one person got on there. Student 3: How will you find out how many got on at Monkey House. Student 2: Well, I think 20 people should have gotten on at Big Cats, but only 16 people did. Maybe if I made 4 more people get on at Monkey House (5 altogether), there would be 20 by the time we got to Big Cats.
