How to Use the Interactive Tools
👩🏫
Teachers
Project a tool in full-screen mode to demonstrate concepts and drive whole-class discussion. Manipulate objects in real time so students can see exactly what is changing — and why.
Tip: Pause to ask “What do you notice? What do you wonder?” before revealing the next change.
📚
Students
Click, drag and explore. Test your hunches and see what happens. The tools let you try things out without worrying about getting an answer wrong — every attempt is a chance to learn.
Tip: If a result surprises you, that’s a great moment — try to explain why it happened.
👨👩👧
Parents
Sit alongside your child and explore a tool together. You don’t need to know the maths — the tool does the teaching, and your job is to share in the noticing and the wondering.
Tip: Take turns making predictions before clicking — it’s surprising how often you’ll both be wrong, and that’s where the maths happens.

🧮
Manipulatives
10-frames, Dienes blocks, Numicon, coins, dice and more to investigate place value and number relationships.
🔴
Place Value Counters
Drag counters into place value columns to build and partition numbers. Exchange between columns to explore regrouping.
🏛️
Place Value Columns
Multiply, divide, add and subtract while watching digits shift through place value columns. See expanded form in real time.
↔️
Addition & Subtraction Number Line
Watch addition and subtraction come alive as animated jumps along a number line. Bridge through zero with directed numbers.
🚶
Multiplication Number Line
Use the walking method to multiply on a number line — face a direction, then walk forward or backward to see why negative × negative = positive.
🔢
Number Grid Explorer
Shade multiples, primes, squares and triangular numbers on a fully customisable grid. Change rows, columns, start and step to reveal patterns.
✖️
Multiplication Grid
Highlight times tables, spot the diagonal of square numbers, find prime products and explore patterns across the multiplication grid.
💯
Fraction, Decimal, Percentage Grid
Shade cells on interactive 100-square grids to explore fractions, decimals and percentages, and how they connect.
💥
Number Smash
Combine any two numbers and add, subtract, multiply and divide. Can you make the target numbers?
🧩
Factor & Multiple Tiles
Split any number into factor pairs, decompose into a product of prime factors, or find the first 5 multiples.
🍕
Fraction Tiles
Investigate fraction equivalence, addition and subtraction with colourful, draggable fraction tiles.
🧱
Fraction Wall
Select fractions to see equivalences, toggle decimals and percentages, compare and add fractions, and reorder rows.
📊
Fraction Bars
Investigate the addition and subtraction of fractions with splittable fraction bars — ideal for bar modelling.
🔄
Double-Sided Counters
Flip counters between positive and negative to model integers, create zero pairs, and explore directed number operations.
📐
Geoboard
Investigate shapes, angles, area and perimeter on a variety of Geoboards — square grid, isometric, coordinate and more.
🎲
Probability Tools
Run probability experiments with coins, dice, spinners and bags. Track convergence, compare snapshots and explore sample spaces.
