When working with students who need additional support in math, having the right tools can make a significant difference. I just completed my third year as a math interventionist. Over those three years I've found that a handful of supplies consistently help students build number sense, stay engaged, and better understand mathematical concepts.
If I could only choose five supplies for math intervention, I would start with dry erase markers, magnetic ten frames, two-color counters, dry erase erasers, and linking cubes. These tools support number sense, problem solving, and student engagement across multiple grade levels.
1. EXPO Low Odor Dry Erase Markers
One of the most effective ways to increase student participation is to give every student a way to show their thinking. Dry erase markers allow students to solve problems, demonstrate strategies, and make corrections without worrying about mistakes becoming permanent.
I use whiteboards regularly for:
- Number sense activities
- Fact fluency practice
- Solving word problems
- Guided math instruction
- Quick formative assessments
These markers write clearly, erase easily, and last longer than many budget alternatives.

2. Magnetic Ten Frames
Ten frames are one of the most powerful tools for helping students develop number sense. They provide a visual representation of numbers and help students understand concepts such as composing and decomposing numbers, making ten, and comparing quantities.
The magnetic version is especially useful because it allows me to demonstrate concepts on a whiteboard while students follow along.
I frequently use magnetic ten frames for:
- Counting and cardinality
- Addition and subtraction strategies
- Making ten
- Number comparisons
- Building fluency within 20

3. Two-Color Foam Counters
Manipulatives are essential when students are developing conceptual understanding. Two-color counters are versatile, inexpensive, and easy for students to use.
I often use them for:
- Addition and subtraction
- Number bonds
- Part-part-whole relationships
- Probability activities
- Integer concepts with older students
Because the counters have different colors on each side, they help students visualize multiple ways to make the same number.

4. Dry Erase Erasers
This may seem like a simple supply, but quality erasers save valuable instructional time. Students can quickly clear their work and move on to the next problem without leaving behind distracting marker residue.
I keep several erasers available during intervention groups because we use whiteboards throughout most lessons.
Benefits include:
- Faster transitions between activities
- Cleaner whiteboards
- Reduced frustration for students
- More efficient practice opportunities

5. Linking Cubes
Linking cubes are among the most versatile math manipulatives available. They help students move from concrete experiences to abstract understanding.
I use linking cubes for:
- Counting and one-to-one correspondence
- Addition and subtraction
- Comparing numbers
- Place value
- Measurement
- Multiplication arrays
- Fractions
Students enjoy the hands-on nature of linking cubes, and they provide endless opportunities for mathematical exploration.

Final Thoughts
While there are many math supplies available, these five tools consistently support meaningful learning and student engagement during intervention groups. They help students build number sense, develop confidence, and strengthen their understanding of key mathematical concepts.
If you're building your math intervention toolkit, these are the supplies I would recommend starting with.
