This document provides instruction on constructing responses to math word problems using the RICE strategy: R - Read and restate the problem. I - Illustrate the problem with a diagram or picture. C - Calculate the solution using math operations. E - Explain how the problem was solved and evaluate the work. Examples are provided of using RICE to solve a word problem about the number of palm trees needed around a rectangular pool. The document emphasizes thoroughly explaining the steps and showing all work.
R i-c-e problem solving strategy
- 2. You will be hearing the words “CONSTRUCTED RESPONSE” this year.
- 3. What is a constructed response? • Let’s break down each word to understand what it means….. CONSTRUCTED RESPONSE make/create/build answers
- 4. Now that you understand the words, how would you finish this sentence? A constructed response is……….. an answer that I create when I am asked a question.
- 5. Here are some questions for you….. What is your favorite season? Draw a picture to illustrate your favorite season and explain WHY it is your favorite season.
- 6. Some of you might construct your response this way: My favorite season is fall because I like to see the leaves changing colors. I love to rake leaves with my family, and I like to go to the pumpkin patch.
- 7. IT IS IMPORTANT to construct our responses to questions in MATH. Is this what you are thinking? There is only ONE answer to a MATH question!
- 8. There are different ways to SHOW HOW you worked out your answer!
- 9. We are going to use the “RICE” strategy to help us work and thoroughly explain how we solve our math problems: R I C E
- 10. R – READ & RESTATE I - ILLUSTRATE C - CALCULATE E – EVALUATE HOW YOU CALCULATE ~ EXPLAIN ~ EVALUATE EVERYTHING!
- 11. READ • READ AND REREAD THE PROBLEM. • WHAT IS GOING ON IN THE PROBLEM? –HINT: PICTURE IT IN YOUR MIND LIKE YOU ARE READING A STORY. • WHAT QUESTION(S) ARE BEING ASKED? • WHAT ARE THE KEYWORDS? • WHAT FACTS ARE GIVEN?
- 12. REREAD THE PROBLEM. PICTURE IT FIND FACTS. LIKE A STORY. READ WHAT FIND QUESTION(S) KEYWORDS. ARE BEING ASKED?
- 13. Let’s READ this problem: Mary’s pool is shaped like a rectangle. The length is 30 feet long and the width is 20 feet long. Her father wants to put a border of palm trees around the perimeter of the pool. The palm trees will be planted 10 feet apart, and there will be a palm tree in each corner. How many palm trees will be planted?

Find facts. each corner. How many palm trees will be planted?
- 15. Take a minute to REALLY picture & understand the information in the problem:
- 16. Next, RESTATE the problem in your own words. TAKE A MINUTE TO REREAD: Mary’s pool is shaped like a rectangle. The length is Now share the 30 feet long and the width problem with is 20 feet long. Her father wants to put a border of your partner palm trees around the perimeter of the pool. in your own The palm trees will be planted 10 feet apart, and words. there will be a palm tree in each corner. How many palm trees will be planted?
- 17. ILLUSTRATE Draw a picture, diagram, or table. Draw something that will help you see and solve the problem. Remember to LABEL your illustration.
- 18. What can I ILLUSTRATE to help me see and solve the problem? 1. Mary’s pool is shaped like a rectangle. 2. The length is 30 feet long. 3. The width is 20 feet long. 30 feet 4. Her father wants to put a border of palm trees around the perimeter of the pool. 20 feet 5. The palm trees will be planted 10 feet apart. 6. There will be a palm tree in each corner. 7. How many palm trees will be planted?
- 19. Is there any need to draw a picture of a palm tree? • The marks and dots work fine. • We want to illustrate in the most efficient way. • EFFICIENT means to make the BEST USE of our time!
- 20. When we work in class we may be able to illustrate in color. 30 feet 20 feet
- 21. On a constructed response test, we are only allowed to have paper and a plain pencil, so our illustration might look like this…..
- 22. Remember….. Everyone illustrates in his/her own way. There is no RIGHT WAY or WRONG WAY to illustrate IF it helps us to see and solve the problem.
- 23. CALCULATE • Plan and solve using a math operation and strategy. Sometimes you will use more than one operation or more than one strategy. • Use that strategy to help you solve the problem. • Show all of your calculations.
- 24. CALCULATE I’m putting an “X” to I have placed marks to help me remember represent the places I which ones have been would put a palm tree – counted. every 10 feet. 30 feet The problem told me that Mary’s father was going to have a palm tree on 20 feet every corner. Next, I need to count to see how many palm trees in all.
- 25. There will be 10 palm trees in all.
- 26. EXPLAIN • Write out an explanation of how you solved the problem. • Explain the strategy you chose and why you chose it. • Write out any thoughts about why you solved it that way. • BE SURE to include all of the steps that you used! Your answer will not be complete if you leave out any steps. • HINT: USE YOUR KEYWORDS FROM THE PROBLEM TO HELP YOU EXPLAIN YOUR ANSWER.
- 27. Here is how I would EXPLAIN my answer for the problem we just worked. I started by drawing a picture of the pool in the shape of a rectangle. I labeled the length 30 feet and the width 20 feet. I know that Mary’s dad is going to plant trees on the perimeter and the perimeter is the edge of the pool. He is planting a tree on every corner so I drew dots on the corners of the rectangle. I knew that the trees will be 10 feet apart so I drew a line to show where the trees would be. Since the length was 30 feet, I started at the corner and I knew that I would divide that side into 3 sections so I drew one line for 10 feet and then another line for 10 feet. After 10 more feet I would end at the corner. The width was 20 feet so I started at the corner and I knew I would divide 20 feet into 2 sections with 1 line. I did the same thing on the other sides of the rectangle. I counted all of the lines and dots and found out that there would be 10 trees planted around the perimeter of the pool.
- 28. Look at how I used my keywords to help me explain my answer. I started by drawing a picture of the pool in the shape of a rectangle. I labeled the length 30 feet and the width 20 feet. I know that Mary’s dad is going to plant trees on the perimeter and the perimeter is the edge of the pool. He is planting a tree on every corner so I drew dots on the corners of the rectangle. I knew that the trees will be 10 feet apart so I drew a line to show where the trees would be. Since the length was 30 feet, I started at the corner and I knew that I would divide that side into 3 parts so I drew one line for 10 feet and then another line for 10 feet. After 10 more feet I would end at the corner. The width was 20 feet so I started at the corner and I knew I would divide 20 feet into 2 sections with 1 line. I did the same thing on the other sides of the rectangle. I counted all of the lines and dots and found out that there would be 10 trees planted around the perimeter of the pool.
- 29. EVALUATE When you EVALUATE you CHECK your work to see if it is accurate and complete. Sometimes I will ask you to EVALUATE someone else’s work
- 30. I am going to show you a list of questions that will help you to evaluate your work.
- 31. EVALUATE EVERYTHING! Did I READ the problem at least twice? Do I understand it? Did I RESTATE the question being asked? Did I underline or highlight the keywords in the problem? Did I underline or highlight the facts that are given? Did I choose a strategy & operation carefully? Did I ILLUSTRATE my work? Did I evaluate my CALCULATIONS? Are my EVALUATIONS correct? Did I EXPLAIN how I solved the problem? Did I include all of the steps I took to solve it? Is my writing clear? Did I label my illustrations or diagrams or tables? Does my answer make sense? Did I answer the exact question(s) being asked?
- 32. R – READ & RESTATE I - ILLUSTRATE C - CALCULATE E – EVALUATE HOW YOU CALCULATE ~ EXPLAIN ~ EVALUATE EVERYTHING!
