The Mandelbrot Set (Activity)
Explore fractals by investigating the relationships between the Mandelbrot set and Julia sets.
Place Value (Discussion)
Discusses what individual digits represent in multi-digit integers.
Compare two sets of objects, using estimation to determine which is greater. Estimate a number of objects, the length of a line, or the area of a shape. Parameter: error tolerance. Comparison Estimator is one of the Interactivate assessment explorers.
