Multiplication and division are the gateway to almost everything that comes after them in mathematics — fractions, ratios, algebra, proportional reasoning, and beyond. Yet for many students, these operations are introduced as procedures and facts before they have the foundational understanding that makes those facts meaningful. The result is students who can recall answers in isolation but fall apart when problems look slightly different or grow in complexity.
This hub brings together the resources, games, and intervention tools from the Multiplicative Thinking Intervention Program in one place. Everything here is designed to build genuine multiplicative thinking — not just fact fluency.
Before a student can make sense of 6 × 7, they need to understand what multiplication actually is. Multiplication is not repeated addition as a trick — it is a way of organizing quantities into equal groups and reasoning about the total. A student who truly understands multiplication can look at an array of 24 objects arranged in 4 rows and immediately see 4 groups of 6, recognize that 24 ÷ 4 and 24 ÷ 6 are both embedded in that same image, and explain why the answer to 4 × 6 is the same as 6 × 4.
Division is not a separate operation to be learned after multiplication. It is the inverse — the same relationship read in the other direction. Students who learn multiplication and division together, as two ways of describing the same equal-group structure, develop far more flexible and durable understanding than students who learn them as two separate sets of procedures.

The starting point for multiplicative thinking. Students build their own equal groups by dragging counters into group slots, working through both multiplication and division problems using hands-on visual models. Covers partitive and measurement division — students experience what equal groups and fair sharing actually mean before they ever write an equation. Best for Grades 2–4 and early intervention. .

Takes students through the full Concrete–Representational–Abstract sequence in a single game. Students work with full equal groups and array models, then partially screened images where they must reason from what they can see, and finally phrase-based problems where they build the equation from language alone. Every level is connected — the concrete always links back to the abstract. Best for Grades 2–5, whole-class instruction, and Tier 2 and Tier 3 intervention.

Builds the critical bridge between multiplication and division. Students use a partially screened image to reason out a missing factor, then in Level 2 connect that equation directly to a division equation using labeled drop zones. The screen unlocks when the correct answer is found, revealing the full image as confirmation. Best for Grades 3–5 and students who are ready to understand why multiplication and division are the same relationship read two different ways.
One of the most important transitions in elementary mathematics is the shift from additive thinking to multiplicative thinking. An additive thinker solves 4 × 3 by counting 3, 6, 9, 12 — adding equal groups one at a time. A multiplicative thinker sees 4 groups of 3 as a single structure and knows the total is 12 without needing to build up to it.
This shift does not happen automatically, and it does not happen through memorization. It happens through sustained, structured experience with equal groups, arrays, and the visual models that make the structure of multiplication visible.
Research consistently shows that students who develop this conceptual foundation before moving to abstract facts and algorithms perform significantly better on complex tasks and retain their understanding over time.
Students who struggle with multiplication and division in upper elementary school have almost always skipped this foundation. They know some facts by rote but cannot apply them, cannot explain them, and cannot extend them. The resources on this page are designed to fill that gap.
When should students develop multiplicative thinking? Most students begin building the foundations in Grades 2 and 3 and should have a solid conceptual understanding of multiplication and division in place by the end of Grade 4. Students who reach Grade 5 still relying on counting strategies for multiplication need targeted intervention.
What is the difference between partitive and measurement division?Partitive division asks how many are in each group when the number of groups is known — sharing 12 cookies among 3 friends. Measurement division asks how many groups can be made when the size of each group is known — putting 12 cookies into bags of 4. Students need experience with both to develop flexible division understanding.
How do I know if a student has not yet made the shift to multiplicative thinking?The clearest sign is that a student still counts by ones or skip counts to solve multiplication problems rather than working from the structure of the groups. Other signs include inability to explain what a multiplication fact means, difficulty with array problems, and confusion when division problems are presented in unfamiliar forms.
Are these resources suitable for intervention?Yes. All of the games and program materials are designed with MTSS Tier 2 and Tier 3 support in mind and are built on instructional approaches with strong evidence for students with math learning disabilities.
