Place Value Machine
Build and break apart numbers with draggable base-10 blocks. See why the position of a digit changes its value.
Your interactive mathematics playground. Drag, build, and visualise your way to understanding — from counting blocks in Year 2 to trigonometry in Year 10.
Each year level has a curated set of tools matched to the Australian Curriculum. Click a year to filter the tools below.
Math Lab is not a quiz. It is a place to explore, experiment, and discover how maths works through interaction.
Browse by year level or topic. Each tool targets one specific concept that students commonly struggle with.
Drag blocks, move sliders, plot points. There are no wrong answers in explore mode — just discovery.
When ready, switch to Challenge Mode. Answer questions that adapt to your level with instant visual feedback.
Every interaction builds number sense and spatial reasoning that transfers directly to tests and exams.
41 tools across 12 categories, covering every strand of the Australian Mathematics Curriculum.
Build and break apart numbers with draggable base-10 blocks. See why the position of a digit changes its value.
Zoomable number line from whole numbers to fractions, decimals, negatives, and surds.

Spin spinners, roll dice, flip coins, draw marbles — run 1 to 1000 trials and watch results converge toward expected probability.
Build multi-stage probability trees. Click a leaf to see the path highlight and compound probability calculate.
Enter data, choose a graph type, and build bar, line, dot, or pie charts interactively. Includes misleading graph challenges.
Add and drag data points on a dot plot. Watch mean, median, mode, and range recalculate in real time.
Fill tanks in a given ratio. Scale up with a slider to see proportional reasoning in action.
Drag Australian coins and notes to pay for items. See change calculated by counting up from the price.
Side-by-side bar charts showing simple vs compound interest growing over time. The visual gap is the entire lesson.
Draw shapes, then reflect, rotate, or translate them with ghost trails showing the transformation.
Snap regular shapes together edge-to-edge. Discover which shapes tessellate and which leave gaps.
Click to plot points, connect them into shapes, and use midpoint and distance tools.
Place unit cubes on an isometric grid to build 3D shapes. See volume count live. Build layer by layer to discover the formula.
See a pattern, extend it, then write a formula and test if it predicts term 50. Includes a Guess the Rule game.
Shop with a budget, apply discounts, calculate GST, and compare unit prices.
Explore real Australian datasets — weather, sport, population. Choose variables, build graphs, spot trends, and detect bias.
Multi-step, no-fixed-method problems with a scratchpad and strategy hints. Optimisation, logic, and estimation challenges.
Design game mechanics — scoring formulas, drop rate probability, XP curves — and playtest your designs.
Research consistently shows that students learn mathematics more deeply when they can manipulate and visualise concepts.
Every tool starts with something visual and tangible — blocks, bars, grids, graphs — before introducing symbolic notation. This mirrors how the brain builds mathematical understanding.
When a student drags a fraction piece or adjusts a slider, the result is immediate. There is no waiting for a teacher to mark work — the visualisation is the feedback.
In explore mode, there are no wrong answers. Students can experiment freely without the anxiety of being marked. This builds confidence before challenge mode introduces structured questions.
Each tool exists because a specific concept confuses students — fractions, negative numbers, area vs perimeter, simultaneous equations. The interaction is designed to address that exact confusion.
Math Lab is SubjectCoach's interactive mathematics playground. It provides 40 hands-on digital tools where students explore maths concepts by dragging, building, and experimenting — rather than just answering questions. Each tool targets a specific concept that students commonly find confusing.
Math Lab covers Years 2 through 10 of the Australian Curriculum. Year 2 students have access to 5 tools, while Year 8 students can explore up to 26 tools. Every tool is labelled with the year levels it applies to.
Some labs are free to use. Math Lab is available to all SubjectCoach subscription holders at no extra cost. Simply visit the Math Lab page and start exploring any tool after you login.
Practice questions test what you already know. Math Lab teaches you by letting you see and manipulate the maths. For example, instead of answering "Which is bigger: 1/3 or 1/2?", the Fraction Wall lets you see the two fractions side by side and visually compare them. The understanding comes from the interaction, not the answer.
Yes. Every tool in Math Lab is mapped to the Australian Curriculum for Mathematics. The tools cover the key strands: Number and Algebra, Measurement and Geometry, and Statistics and Probability.
No. Teachers can't assign specific Math Lab tools to individual students or whole classes through the SubjectCoach teacher dashboard, just like practice sessions. These tools are to explore in classrooms or independently by students.
Math Lab works on desktops, laptops, tablets, and Chromebooks. All tools are touch-friendly and responsive, designed for school devices.
Math Lab is a collection of 41 interactive mathematics tools built for Australian students in Years 2 through 10. Unlike traditional worksheets or multiple-choice quizzes, Math Lab lets students explore mathematical concepts hands-on through drag-and-drop interfaces, real-time graphs, animated visualisations, and guided challenges.
Younger students work with tools like the Place Value Machine, where they drag base-10 blocks to build numbers and watch 10 ones snap into a ten. The Fraction Wall shows fraction bars stacked so students can see at a glance that 2/4 equals 1/2. The Clock Playground lets them drag clock hands with a synced digital display, and the Area vs Perimeter Sandbox finally separates these two constantly confused concepts with colour-coded grids.
As students move into algebra, the Balance Scale Equation Solver makes "do the same to both sides" physical. The Order of Operations Stepper highlights which part of an expression gets evaluated next. The Chance Simulator lets students run 1,000 coin flips and watch experimental results converge toward theoretical probability — something a worksheet simply cannot demonstrate.
Older students work with the Linear Function Laboratory (sliders for gradient and y-intercept with live graph updates), the Parabola Playground (see the effect of each parameter in turning-point form), and the Pythagoras Proof Playground with its animated water-pour demonstration. The Unit Circle Navigator for Year 10 draws sin and cos graphs in real time as a point travels around the circle.
Every tool in Math Lab maps directly to the Australian Curriculum for Mathematics. The tools cover Number and Algebra (place value, fractions, ratios, equations, functions), Measurement and Geometry (area, angles, Pythagoras, trigonometry, transformations), and Statistics and Probability (data representation, chance experiments, statistical measures).
