**Adapting for Extended Response Questions**

Thinking like a Mathematician Adapting for Extended Response Questions

22
**Brainstorm ways to solve this.**

What do I know? Brainstorm ways to solve this. What do I want to find? Try it here. Things I need to include in my extended-response write up Dr. Alan Zollman, Northern Illinois University Four-Corners Extended Response

23
**Write what you know from the problem. **

Second Paragraph Write what you know from the problem. “What I know from the problem is …” Third Paragraph Show your strategies you will try. “So what I first tried to do was …” Fourth Paragraph Show your solution. “Using numbers this is …” First Paragraph Write what you are to find. “First, what I want to find is ..” Fifth Paragraph Explain your answer. “Therefore, what I did was …” Dr. Alan Zollman, Northern Illinois University Four-Corners Extended Response

MARTY’S SANDWICHES Marty loves sandwiches. He likes hamburgers, hot dogs, and fish sandwiches. He loves sandwiches with anything on them! He always puts exactly one type of topping on his sandwich: either ketchup, mustard, mayo, or even taco sauce. Marty says that for lunch he can eat a different one-topping sandwich everyday for 2 weeks without having the same thing. Can this be true? Explain why.

**Helping students self-reflect**

In cooperative groups have students: Design an abbreviated rubric that includes mathematical knowledge, strategy, and explanation Assess “student” work using rubric Give recommendations to the “student”

**The growing of good corn**

66
**I was raised on a farm in Indiana.**

We had chickens, pigs, dairy cows. We grew alfalfa, clover, soybeans, tobacco, oats, wheat, and especially corn.

67
**Everyone who plants corn wants to have a good crop of corn.**

Initially, it requires money for good seed, fertilizers, insecticides, herbicides, and then a lot of time and effort.

68
**No one can make corn grow.**

You nurture the corn to allow it to grow.

69
**Corn cross-pollinates. Fields of corn are needed.**

You can’t plant one lone seed of corn to get corn. You can’t plant one row of corn to get corn. Corn cross-pollinates. Fields of corn are needed.

70
**You need your neighbors to grow good corn if you want good corn.**

You get the best corn when you and all your neighbors all grow good corn. You need your neighbors to grow good corn if you want good corn.

71
**Thank you for helping me grow good corn by being good neighbors!**

- Alan
