This math word wall covers the area formulas and dimension variables for squares, rectangles, parallelograms, triangles, trapezoids and circles.
Included are 6 shape posters with variables, pieces that define the variables and pieces that give each shape's area formula. The word wall is black and white so that you can color it the way that best works for your students.
*Please note that photos show rectangle references with L for length. I have since updated with additional pieces with l so that you can choose which to display.
