Control charts can be printed to size or enlarged for presentation and/or display. Due to the dimensions used in this decanomial (1 = .4in or 1.016 cm), students can measure the sides to the closest cm and accurately calculate quantity, enforcing the equation for area of a rectangle.
Can be printed as many times as wished for individual teacher use or copied onto cardstock, laminated, and cut apart as a classroom set.
