Use this 7-problem quiz/practice to help understand what happens in subdivision with different weights

This 7-problem quiz/practice helps students understand how different weights effect the subdivision shape.

Points on the control arm: Let's start with a shape with four control points, AAAA, BBBB, CCCC and DDDD, then use subdivision with weights (1,1)(1, 1)(1,1)left parenthesis, 1, comma, 1, right parenthesis.

This is 4-problem quiz/practice. What of the following weights could be used for the subdivision algorithm to give us a fractal?

This interactive tool helps students to better understanding weighted subdivision.
