Algebra tiles (tacitle)

A tactile version of algebra tiles. The small yellow squares represent 1, the green rectangles represent x and the large blue squares represent x^2.
The reverse with black raised lines is the negative.
Can be used
- as manipulatives to solve basic equations.
- to demonstrate expansion using the area method.
- to demonstrate factorisation using the area method.
- to demonstrate completing the square
For a kit print 4 x^2 tiles, 12 x tiles and 20 ones.
