Hands down the best virtual manipulative site that I've ever come across. You
can manipulate the tools to meet the needs of your lesson and access so many
lessons. Amazing stuff

Polypad is quickly becoming the magical locus for most students/teachers and
their interactivity with mathematics – and the joyous experiences that result!

Mathigon is one of the greatest math resources out there on the internet, no
question.

Mathigon is on its way to revolutionise maths teaching as we know it and what an
honour to have explodingdots in their mix!

Andrea Biro
@mrsbistro
Can’t get over how much of a game changer Polypad is. I can manipulate the tiles
and write/type on the screen as we go through the lesson together. Ss practice
on their own canvases and I can see their work. Beautiful.

If you haven't checked out Polypad and taken time to explore all its features,
you're seriously missing out!

Brad Vodden
@MrVodden
If you are looking for some online math manipulatives, Mathigon is a game

Wow. The Mathigon Polypad is a game changer! It fits perfectly with middle years

Great reaction from a teacher I was working with today when I shared a task
using Mathigon tiles - "I must let the rest of the team know about this
site."!!! Highly recommend you take a look at

Polypad is an absolute game changer and I've only known about it a few months.

Mathematical play. Which part of the Polypad are you drawn to play with most?
This Mathigon playpit has been a go-to tool during Maths Teacher Circles
explorations.
