| Step Number | Step Title | Length | Details |
|---|---|---|---|
| 1 | Introduction to R.I.C.E. Method | 5 min | Briefly explain the R.I.C.E. method: Read the problem, Identify the important information, Compute the answer, and Evaluate the result. |
| 2 | Distributing Printable Cards | 5 min | Hand out printable cards to each student. Explain that they will fill in these cards during the lesson as they work through word problems. |
| 3 | Guided Practice | 10 min | Work through a sample word problem as a class using the R.I.C.E. method. Engage students by asking questions at each stage of the process. |
| 4 | Group Activity | 5 min | Divide the class into small groups (4-5 students each). Assign each group a different word problem to solve using the R.I.C.E. method. |
| 5 | Collecting/Checking Cards | 3 min | Have students collect their cards and pass them to the teacher for random checking. This step provides insight into their understanding without presentations. |
| 6 | Assigning Homework | 2 min | Assign homework related to addition and subtraction word problems using the R.I.C.E. method. Explain that students will complete this at home. |
Students will complete a worksheet involving addition and subtraction word problems using the R.I.C.E. method, which will be checked on the following day.
"Good morning, class! Today, we’re going to learn about solving addition and subtraction word problems using a special method called the R.I.C.E. method. Can anyone guess what R.I.C.E. stands for? That’s right! It stands for Read, Identify, Compute, and Evaluate!
Let’s go over each step together:
This method will help us tackle word problems in a fun and organized way!"
"Now, everyone, I'm going to hand out these printable cards to each of you. These cards will help you remember the steps of the R.I.C.E. method as we go along.
As you fill in your card, think about what we just discussed for each step. Keep these handy, because we’ll be using them throughout our lesson!"
"Next, let’s try a word problem together using the R.I.C.E. method. Here’s the problem: 'Sarah has 8 apples, and she buys 5 more. How many apples does she have now?'
First, let’s Read the problem. What does it say about Sarah?
Yes! She starts with 8 apples! Now, let’s Identify the important information. What do we need to find out?
Correct! We need to find out how many apples Sarah has altogether.
Now, who can help me with the Compute step? What math operation should we use here?
That’s right! We will add 8 and 5 together. What do we get?
Great job - 13! Finally, let’s Evaluate. Does it make sense that Sarah has 13 apples now? Yes, it does!
Wonderful work, everyone! You've just solved a word problem using the R.I.C.E. method!"
"Now, it's your turn to practice! I'm going to divide you into small groups of 4 to 5 students. Each group will receive a different word problem to solve using the R.I.C.E. method.
Once you've got your problem, work together to Read, Identify, Compute, and Evaluate. Remember to use your printable cards to guide you through each step. I’ll be walking around to help you if you get stuck, so don’t hesitate to ask questions!"
"Okay, everyone! It’s time to wrap up our group activity. Please collect your cards and pass them to me. I'll be checking them randomly to see how well you understood the R.I.C.E. method.
While you pass your cards up, remember that I’m looking for how you applied each of the steps in your work. You all did fantastic during group work—let’s see what you’ve written down!"
"Finally, for homework, I want you to complete a worksheet with more addition and subtraction word problems using the R.I.C.E. method.
Please take this home and work through it just like we practiced today. We’ll check your homework together tomorrow. If you have any questions while working on it, feel free to ask me when you come in.
Great job today, class! I’m proud of the effort you've put into learning this method."

Read the following word problem carefully: "Tom has 10 marbles, and he gives 4 of them to his friend. How many marbles does Tom have left?"
Identify the important information in the problem.
Compute the answer using the appropriate mathematical operation.
Evaluate your answer.
Laura collected 15 sticks, and she found 9 more in the park. How many sticks does she have now?
In a garden, there are 24 flowers. If 7 of them wilted, how many flowers remain healthy?
Create your own addition or subtraction word problem and solve it using the R.I.C.E. method.
