Pascal's Triangle (Hands-on with Blocks)

Discover the power and beauty of Pascal’s Triangle in this engaging, hands-on video tailored for Lower Secondary Mathematics students and their teachers. Using colourful 2 cm blocks, this lesson not only builds the triangle row by row but also reveals a treasure trove of mathematical insights—including patterns in powers of two and eleven, triangular numbers, combinations, fractals like Sierpiński’s Triangle, and even the binomial theorem. A special highlight is the physical model of the Tetrahedral Numbers, built layer by layer with blocks to visualize their 3D structure. Designed as a rich foundational topic, Pascal’s Triangle equips students with concepts they’ll revisit in Upper Secondary, making it a perfect crossover topic. With a downloadable worksheet, practical activities, and historical context, this video is an ideal resource for classroom use or independent exploration. ----------------------------------------------- The free worksheet can be downloaded from https://mathswithgeoboards.com/course/blocks-coins-and-dice/ ------------------------------------------------ A set of 100 x 2cm cubes can be bought online from Amazon : https://www.amazon.com/dp/B000URL296?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1 ----------------------------------------------
