A complete library of classroom-tested resources — puzzles, music, art, and more. Everything a teacher needs to make math unforgettable.
These interactive puzzle booklets turn basic arithmetic into a detective game. Students use addition, subtraction, multiplication, division, fractions, decimals, and percents to crack a 5-letter code word hidden inside each puzzle. With different puzzle sets designed for different skill levels and age groups, every student gets the right level of challenge. This is not rote learning — it is engaging, game-like practice that keeps students coming back for more. When students are solving a mystery, they forget they are doing math.
ArithmeCode Junior
ArithmeCode Go Figure
Learn every times table up to 10 through catchy, memorable songs. The method is simple and proven: if students learn the songs, they know the tables. Each multiplication fact gets woven into a melody that sticks in the brain long after the music stops. Teachers report that students start humming the songs during tests — and getting the answers right. This CD has helped thousands of students build the foundational fluency they need to succeed in higher math.
Included with the music CDs, these cool finger math techniques give students a kinesthetic, hands-on way to work through multiplication problems. Students who struggle with memorization often thrive when they can use their hands as tools. Finger math turns the abstract into the physical — and for many learners, that is the breakthrough moment. It is math you can literally feel.
A collection of math-music connections designed for middle school and early high school students. This CD ties mathematical concepts into musical ideas in ways that make abstract operations memorable and fun. When students hear a rhythm in a fraction or a pattern in an equation, math stops being something they endure and starts being something they enjoy. The connections are creative, unexpected, and surprisingly sticky — students remember the math because they remember the music.
ArithmeCode Standard
ArithmeCode Integer-Logic
Trigonometric Operetta (Math Music in Mayhem)
The follow-up to the original, packed with even more math-music connections. New songs, new concepts, and new ways to make the abstract concrete. If the first CD got students hooked, this one takes them deeper. Teachers who use both CDs report that students start making their own connections between math and music — which is exactly the kind of creative thinking that sticks for life.
Higher-level puzzle booklets that build on the elementary series with more complex operations. These puzzles challenge middle school students with multi-step problems, algebraic thinking, and trickier number relationships — all while keeping the same engaging, code-cracking format that makes students want to finish every page. Ideal for students who have outgrown the basics but still love a good challenge.
Ten paper folding constructions with mathematical connections illustrated step by step. This DVD brings hands-on geometry, symmetry, and spatial reasoning into the classroom in a way that textbooks simply cannot. Students who learn by doing — and that is most of them — light up when they can fold, crease, and build their way to understanding. Each construction reveals a mathematical principle hiding in plain sight, from basic symmetry to surprising geometric relationships.
Ten more paper folding constructions exploring different mathematical concepts. Part 2 goes further, tackling more advanced geometric ideas and spatial puzzles. Students build on the skills they developed in Part 1 and discover that the deeper you go, the more fascinating paper folding becomes. It is hands-on math at its best — tactile, visual, and full of surprises that make students rethink what geometry can be.
Ruler and compass math art — where geometry meets creativity. This DVD teaches the fundamentals of geometry through creating artwork with nothing more than a ruler and a compass. Students learn about angles, arcs, bisectors, and constructions while producing pieces they are genuinely proud of. As Dave puts it: "Interesting ways to learn about some of the fundamentals of mathematics and have some fun with it in the form of artwork." For students who think they do not like math, this is often the material that changes their mind.
A simple, memorable song that helps students remember what matters most in circles.
Radius vs. diameter. Pi R squared for area. Pi D for circumference. These are the facts students forget under pressure — unless they have a song stuck in their head. Viewed over 3 million times and counting, mainly across Canada, the United States, and England, this song has helped countless students ace their circle questions. With hundreds of positive comments from teachers, students, and parents, it has become one of Dave's most impactful creations.
Views and Counting
Dave works directly with schools, districts, and educators to put these resources into classrooms where they can make a real difference.
"I play this for my Grade 6 class every year before our geometry unit. They sing it during tests and get the answers right every time. Absolute lifesaver!"
"I'm in college now and I STILL remember this song from 7th grade. Just used it on my calculus exam to double-check a circle problem. Thanks Dave!"
"My daughter was struggling with circles and found this video on her own. She went from a C to an A on her next maths test. We are so grateful!"
"Simple, catchy, and it works. I teach high school and even my Grade 10s hum this when they see a circle problem. 3 million views well deserved."
