Make measurement concrete.
The shape is only the starting point. Here's where the real maths happens.
Compare area and perimeter
Build two shapes with the same area and ask students what happens to the perimeter. It's one of those lessons where a big concept clicks in a single whole-class conversation.
Model units clearly
Show totals, segment lengths and grid lines so students can connect counting edges to measurement. No worksheet required.
Predict, then reveal
Build a shape, hide the numbers and ask students to estimate. Reveal the answer when they're ready and turn the perimeter into a discussion instead of a guess.
Perimeter Explorer is just the beginning.
More visual tools designed to spark discussion, model concepts and make thinking visible.
Number Line
Skip-count, jump, and partition on a customisable number line. The visual backbone of so many maths conversations.
Fractions
Compare, equivalent, add, and subtract fractions with bars and circles you can manipulate live on the board.
Phoggle
The literacy cousin of Noggle. Same hexagonal grid, but with letters - perfect for word-building warm-ups.
Buzzboard
Mental maths rapid-fire. Project a board of facts and run quick rounds with the whole class.
Word of the Day
A daily vocabulary warm-up your class settles into. Pick a word, explore it together, and build rich language habits one morning at a time.
Classroom tools
Everything you need to keep lessons flowing. Pickers, timers, noise meter, and grouping tools, ready whenever you need them.
Perimeter Explorer belongs on the board.
Project Perimeter Explorer for the whole class and build shapes together in real time. Compare ideas, test predictions and make area and perimeter visible as students explain their thinking.
Project
