Shape SorterShape SorterDrag the shapes into the correct bins showing their Polygon Names.
Get ready for a sorting challenge! Drag each shape into the correct bin, but be careful—one wrong move and the game freezes, sending you back to the start! Stay sharp, and if you manage to place every shape perfectly, a shiny trophy awaits you.
Polygon Names - triangles have three sides, quadrilaterals have four sides and pentagons have five sides.
Line Symmetry - also known as reflection symmetry, occurs when a shape or pattern can be divided by a line (called the line of symmetry) into two identical halves that are mirror images of each other.
Solid Shapes - you will need to decide which shape the image most closely resembles. Shape in real life may not be mathematically perfect.
Prism or Not - a prism is a 3D shape that has two ends that are the same shape and size, and the sides are made up of rectangles connecting those two ends. A cylinder is not technically a prism because its ends are circles, not polygons.

"HI John, I love the puzzles in the newsletter, thank you. They are just what I need to get my students to challenge themselves while they visualise shapes and logic. Happy New Year!"

"These games are pleasantly challenging! I have to actually think hard to figure it out!"

"It's annoying how when I get a question wrong I have to reset the whole puzzle. You should fix that, so people don't have to start again when they get the last question wrong.
[Transum: Thanks for your message and for giving the puzzle a go!
You're absolutely right — it can be frustrating to have to start again when you get one wrong, especially if it's the last one. But there's a reason for it!
This puzzle is designed to be a proper challenge, like a brain-training game. If you could keep dragging the shapes around until everything was right, it would be more of a guessing game than a thinking one. Making a mistake means you have to rethink your strategy — and that’s part of what helps your brain grow stronger!
It’s a bit like a memory challenge and a logic puzzle rolled into one. Getting it all correct in one go really shows you understand the properties of the shapes — and that’s what earns you the trophy.
Keep trying — you’re learning more each time!]"
