####Sequence of Cubic Numbers and Multiplication Table
Cubic numbers (1, 8, 27, 64, ...) can be obtained from the multiplication table. For example, 64 = 4 + 8 + 12 +16 +12 + 8+ 4 =4 x ( 1 + 2 + 3 + 4 + 3 + 2 + 1).
In general, n^3 = n x Σ (1, 2, 3, ..., n-2, n-1, n, n-1, n-2, ..., 3, 2, 1) = n x n^2.
Of course, there are other ways to play with the multiplication table. Have fun!
STEAM educator, learning from and working with K-12 STEAM teachers to explore new ideas of teaching and engagement. I firmly believe ART is at the core of STEM learning or all human learning! I owe my ideas and designs to the hundreds of K-12 children and teachers and university professors I have had the pleasure of working with, in multiple disciplines-- math, science,engineering language arts, social studies, early childhood education and more! All mistakes, of course, are mine! There is no warranty or liability whatsoever implied or explicit behind the designs or ideas. They are all posted for their potential educational values.
When working with children, please strictly observe all safety and health procedures! Please refer to the NSTA safety guides: http://www.nsta.org/safety/.
