The decanomial (without numbers) is considered a Montessori sensorial material of early childhood and is revisited throughout the elementary years to support mathematics instruction in numeracy (multiplication) and pre algebraic concepts (sum of squares)

Multiple lesson suggestions for classroom use
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.
The early level of this presentation enforces the concept of basic facts, useful in supporting Static and Basic Abstract Multiplication using the Elementary Montessori 6-9 Arithmetic Overview.
