Building the Decanomial Square

By February 15, 2019Uncategorized

The Montessori mathematics curriculum allows the students to construct their learning using specially designed materials, then move towards abstraction at their own pace. The Upper Elementary Level 1 students build the decanomial square, which is a concrete representation of the multiplication tables from 1-10. Next, they were introduced to a visual and tactile experience of “squaring” where they could actually count the squares of numbers (2×2, 5×5, 9×9, etc) and physically see that they are, indeed, squares. Finally, they labeled the decanomial square using multiplication facts. It was a two-day, collaborative lesson complete with follow-up work that included making their own decanomial square on paper to keep in their notebooks.

“Children display a universal love of mathematics, which is
par excellence the science of precision, order, and intelligence.”
