Where every student becomes a math person.

Build a mathematical mindset and deep conceptual understanding in every student!

"For too long, maths has been taught as a performance subject—a race to the right answer. Neuroscience tells us a different story. At Struggly, we’ve designed rich, visual tasks that are low-floor and high-ceiling, so that every student can find a way in and be challenged."

Built for deep understanding and lasting mastery

Neuroscience shows that math isn't just one "center" in the brain—it’s a team effort between visual, spatial, memory, and reasoning networks.

Struggly’s tasks are built by teachers and math experts to engage the whole brain. We help students move beyond memorization to achieve deep understanding and long-term mastery.

Our core learning principles

Growth mindset

Math isn't about "being a natural"—it’s about effort, strategy, and persistence.

Multi-dimensional math

Math is explored through visuals, manipulatives, and multiple ways of thinking.

Low floor–high ceiling

Easy entry and scaffolded complexity gets every student exploring math at every skill level.

Student engagement

Students are intrinsically motivated through play, curiosity, and meaningful challenge.

Conceptual understanding

Students build understanding through reasoning, and sense-making.

Procedural fluency

Procedural fluency grows from understanding, supporting flexibility.

Low-floor + high-ceiling

Equivalent Fractions

Partitioning and part whole relationships

Through visual partitioning, students reason flexibly about fractions, adjusting denominators to clarify how much of the whole is shaded.

Level 20

Level 1

Shapes & Vocabulary

Shape Vocabulary and Attributes

Students build shape recognition and vocabulary by matching shapes and colors, developing careful attention and visual discrimination through playful practice.

Level 20

Level 1

Addition

Reasoning with addition within 20

Students use addition and number sense to complete shape patterns, reasoning about balance and constraints while engaging in early algebraic thinking.

Level 11

Level 1

Measurement

Comparing volumes across units

Students compare volumes by reasoning about units, magnitude, and place value, connecting milliliters and liters with fractions and decimals

Level 20

Level 1

Decimals

Visualizing tenths and hundredths

Students build decimals with visual area models, connecting tenths and hundredths to fractions out of 100 while developing flexible place value understanding.

Level 11

Level 1

Making 10

Developing Number Sense with 10

Students use dice to compose 10 in multiple ways, developing addition flexibility, number sense, and spatial reasoning.

Level 4

Level 1

Students don’t quit when it gets tough

Math isn't about "being a natural"—it’s about effort, strategy, and persistence. We build resilient learners who keep going when it gets tough!

Try a task

There have been times when my most challenged math students end up outperforming their peers when using Struggly. By working at tasks that are visual and hands-on, many kids discover that they are actually mathematicians, even if they haven’t always been successful in traditional learning. Struggly allows students to look at math in a different way.”

Grow conceptual understanding

Equations

Solving for unknowns in equations.

Students reason about totals and unknown values using visuals, connecting their thinking to equations and building understanding of multi-step solving.

Fraction Division

Making Sense of Dividing by Fractions

Students use visual models to reason about fraction division, connecting area representations to equations and making sense of the “keep, change, flip” algorithm.

Multiplication

Visualizing Factors and Products

Students connect equal groups, skip counting, and visual numbers to see how factors form products and reveal number properties like even, odd, and prime.

perimeter

Perimeter as linear measurement

Students unroll polygons into linear measurements, using motion and visuals to make sense of perimeter in ways that go beyond static pencil-and-paper methods.

Students persist by choice, leading to mastery

Game-based design captures attention, sustains engagement, and builds students stamina to tackle grade-level rigor with confidence. In Struggly, students aren’t distracted by games; they’re playing math.

Build procedural fluency

skip-counting

From skip-counting to multiplication

Connects repeated addition, skip counting, multiplication and division. Build the multiplication table from scratch to understand and see arrays.

Multiplication Facts

Connecting representations for fact fluency

Students build fact fluency by sorting cards that show products in multiple ways—expressions, arrays, dice, and models—connecting understanding to recall.

Addition with Regrouping

Understanding place value in regrouping

Students visualize regrouping in multi-digit addition, connecting place value to trading units across ones, tens, and hundreds.

Area & Perimeter

Making sense of area & perimeter

Students build shapes to match target area and perimeter, seeing how the same area can create different perimeters through

"I like Struggly because it actually makes me think yet it is super fun at the same time."

5th grade student

Princeton Intermediate School

"Struggly is a game perfect for your brain because it challenges you to think."

5th grade student

Princeton Intermediate School

"Struggly is a good application to help with creating a growth mindset. Before Struggly, my mindset was more fixed about puzzles and challenges and now I am excited to challenge myself."

5th grade student

Mulberry Elementary School

"The thing I enjoy about Struggly is it always makes you find a way and try new things. What I find challenging is that it's hard – I don't really know how to word it – but it's hard."

5th grade student

Princeton Intermediate School

"Struggly is a struggle sometimes, so that's why its name is Struggly. I like Struggly because it is hard and it stretches my brain. It is awesome. Struggly is an awesome program."

5th grade student

Princeton Intermediate School

I would say Struggly is hard and fun in a good way. It taught me that struggling is not a bad thing."
