Cubing a Binomial (6 + 3)³ from the First Term
Here, children start with the big cube of 6³ and build outward:
🔷 Add three 6×6 squares to each side
🔷 Identify the remaining spaces
🔷 Fill all gaps with squares of 3 (six times)
🔷 Watch the cube expand into (6 + 3)³
This presentation shows the distributive law in three dimensions—without ever naming it.
Montessori math makes algebra visible.
