In order to support your student's ability to apply math rules and concepts, it is important to use an inquiry-based approach that enables them to recognize patterns and make connections between new and previously learned material. This page includes intervention strategies that you can use to support your student's understanding of math rules and concepts. As you read, consider which of these interventions best aligns with the particular misconception your student is having.
Explicitly Teach Why Math Rules & Concepts Help Us
Before you use an inquiry-based approach to intervene to support your students' understanding of mathematical concepts and ideas, you should start by explicitly teaching the student why it's important to understand the rules and concepts that are always true about math. This sounds like:
Inquiry-Based Activity A: Pattern Recognition
If your student struggles to understand a mathematical rule, teach him to recognize the rule by looking for a pattern across a series of problems that adhere to that rule. First, introduce a set of problems that reveal a new (or previously learned) rule that the student has not yet mastered. Then, have the students solve the problems, prompting and questioning to support rule recognition. This might sound like, "I notice that when you add zero to 5, the sum is the same number, 5" or "What do you notice happens every time you add zero to a number?" (Clemens & Sarama, p. 192). Then, she encourages the student to "test out" their theory to see if the pattern or "rule" that they identified is true. This structure of practice and repeat continues until the student can explain and apply the rule fluently. Note: This strategy can be used for any math concept or principle, since every concept or principle can be demonstrated across multiple problems!
Pattern Recognition in Action
As you read the following lesson plan, consider the steps the teacher takes to help the student notice the pattern.

Inquiry-Based Activity B: Relational Thinking
If your student is having trouble understanding the fundamental properties of operations, teach him to use Relational Thinking (Carpenter et al., 2015). This strategy teaches a student to become more aware of the properties that he is using so that he can better draw connections between the different operations.

As you read the PDF below, consider: What kinds of questions is the teacher asking to help students make connections? How do these questions help enable a student to better understand operations?

Think about the following scenario, which takes place after a teacher has taught a student the rule that A x 0 = 0 by having the student identify a pattern across problem types.
Teacher: "Let's practice applying the rule that any number times zero equals zero. What's
10 times zero?
Student: "10?"
In such a case, what might you do?
When you are planning your lessons, you should anticipate that your student will make errors throughout. Here are a series of prompts that you can use to respond to errors. Keep in mind that all students are different, and that students might respond better to some types of feedback than to others.
Level of Support | Description of Scaffold | Script |
---|---|---|
Smallest Scaffold | Check his resources. Ask your student to go back to the rule he just figured out. | "Let's go back to your notebook. What is the rule?" |
Medium Scaffold | Back it Up. If a student is struggling, back up your process. Go back and revisit the previous example, and then the current example, and see if the student can extend the pattern. | "I can see that you are stuck. Let's go back. What is 1 x 0? 0. What is 2 x 0? 0. What is 3 x 0? 0. What pattern do you see? Okay! So, what's 10 x 0?" |
Highest Scaffold | Model. If the student continues to struggle, model how you apply the rule to solve this problem. | "I can see that you are stuck. Let me show you how I use the rule we just discovered to solve this problem..." |
If your student struggles to meet your objective, there are various techniques that you might try in order to adjust the activity so as best to meet your student's needs.

All Activities | Speak Up! If a student struggles to recognize the pattern across the problems you've chosen, use your voice or visuals to emphasize the patterns you are finding. That means you may make him say "0" or "0 again!" loudly when thinking aloud about the sums that you're getting, or you may color code the zeroes in the answer to help them stand out. | "Look at what I notice when I begin to recognize the pattern. 1 x 0 is 0. Hmm... That factor is the same as the product. 2 x 0 is 0. The factor is the same as the product AGAIN! 3 x 0 is 0. Oh my goodness, the factor is the same as the product ANOTHER TIME! What do you think the pattern I identified is?" |
All Activities | Connect the Dots. If a student struggles to connect a problem to things he has already learned, make those connections explicit for him by giving him examples, or reviewing old work that shows how he has used similar skills in the past. | "Let's review the work we did yesterday. Can you see how we decided that 8 + 0 was the same as 0 + 8? How did we come to that conclusion?" |
