Mr. Lee's Learners

  When students struggle in mathematics, it's often because they've been asked to work with abstract symbols before developing a conceptual understanding of what those symbols represent.  One instructional framework that can help bridge this gap is the  Concrete, Representational, Abstract (CRA) approach . CRA is an evidence-based teaching strategy that moves students from hands-on experiences to visual representations and finally to symbolic notation. The goal is not simply memorization, but deep mathematical understanding. Research suggests that moving between concrete materials, visual models, and abstract symbols helps students build stronger mental representations of mathematical concepts.  Disclosure: As an Amazon Associate, I earn from qualifying purchases.

Number sense is the foundation of mathematical understanding. When students develop strong number sense, they are able to reason about numbers, recognize patterns, and apply efficient strategies when solving problems. However, many students who struggle in mathematics have underlying number sense gaps that continue to affect their learning as concepts become more complex. As a math interventionist, I've found that identifying and addressing these gaps can often lead to significant student growth. Here are five common number sense gaps that can impact math success and ideas for supporting students. Disclosure: As an Amazon Associate, I earn from qualifying purchases.

One of the biggest challenges in math intervention is knowing whether students are actually making progress. It's easy to assume that students are learning because they seem engaged during lessons. However, effective intervention requires more than observations alone. Progress monitoring helps us determine whether students are responding to instruction and allows us to make informed decisions about next steps. The good news is that progress monitoring doesn't need to be complicated or time-consuming. You can find all resources mentioned in this blog post by visiting my  Amazon Storefront . 

One of the most common questions I hear from teachers and interventionists is: "How do you stay organized when working with multiple intervention groups?" When I first started providing intervention services, I spent far too much time planning, sorting materials, and trying to remember which students needed which skills. Over time, I developed a simple system that allows me to organize my intervention groups in about 25 minutes each week. The goal isn't perfection. The goal is to spend less time organizing and more time helping students. Disclosure: As an Amazon Associate, I earn from qualifying purchases. This comes at no additional cost to you.

Math intervention can be incredibly rewarding, but it can also be frustrating when students aren't making the progress we expect. Over the years, I've learned that sometimes the biggest barriers to student growth aren't the students themselves—it's the instructional decisions we make. Here are seven common math intervention mistakes I've seen and what to do instead. Disclosure: As an Amazon Associate, I earn from qualifying purchases. This comes at no additional cost to you.

Number sense is the foundation of mathematical success. Students who develop strong number sense are better able to solve problems, recognize patterns, and apply efficient strategies when working with numbers. As a math interventionist, I've found that small group instruction provides the perfect opportunity to strengthen number sense skills through hands-on activities and meaningful mathematical discussions. Here are 10 number sense activities that I regularly use during intervention groups.  These activities are particularly important for kindergarten and first grade groups that provide the foundation for future grades.   1. Quick Dot Images Show students a dot image for 2–3 seconds and ask them how many dots they saw. Encourage students to explain how they knew the quantity rather than simply counting each dot. This activity helps students: Subitize quantities Recognize number patterns Build mental math skills Classroom Tip:  Ask students, "What did you see?" instead o...
