Classroom and homeschool

TileWhirl trays turn math into something you can hold. Every pattern is free to print, so a class can share trays and still each have a pattern.

Group murals for the square tray

Each student builds one 12 × 12 plate on their own square tray. When the trays are pushed together, the plates join into one big picture: a T. rex, the Statue of Liberty, a nine-block quilt. Every plate fits in one standard box, so nobody has to share tiles.

32 murals for groups of 3, 4, 6 or 9 builders (6 for 3, 13 for 4, 10 for 6, 3 for 9). Each one has a printable sheet per student with that plate's tile counts and a map showing where it goes.

What group murals teach

TopicTry this
Coordinates and scalePlates are labeled like a grid: A1, A2, then B1. Inside each plate, rows A to L and columns 1 to 12. Ask where tile D7 of plate B2 sits in the whole mural.
Area and multiplicationA 3 × 2 mural has 6 plates of 144 tiles. How many tiles in all? Check against the number on the page.
Quilt geometryIn the quilt murals each plate is a complete quilt block. Find the lines of symmetry in one block, then in the whole quilt.
FractalsThe Fractal Tree repeats the same branching shape at smaller sizes. Where does the pattern stop, and why?
Estimation and dataBefore building, estimate how many tiles of each color your plate needs. Then compare the counts across all the plates.
TeamworkPlates have to line up exactly at the edges. Neighbors check each other's seams before the reveal.

What the trays teach

TopicTry this
Counting and dataEach pattern lists its tile counts. Ask students to predict the counts before they build, then check.
CoordinatesSquare patterns use rows A to L and columns 1 to 12. Call out positions like "red at D7" and build a picture together.
Fractions and percentagesWhat fraction of the Heart pattern is red? Of the whole tray? Compare two patterns.
SymmetryMirror Match and Spin challenges on the triangle, star and hex trays. Why does the star need every color count to be a multiple of five?
Odd and evenThe star tray can't be colored with two alternating colors, because five is odd. Students can discover this themselves.
Shapes and tilingFour hex tiles make a bigger copy of the same shape, and nine make an even bigger one. The hex tray's layouts show it.
Logic and proofThe hex Spiral Problem: possible on paper, impossible from the box. Why?
