Lesson  (...)
Lesson: Introduces students to arithmetic and geometric sequences. Students explore further through producing sequences by varying the starting number, multiplier, and add-on.

Lesson: Introduces students to the concepts of surface area and volume.

Activity  (...)
Activity: Create your own affine cipher for encoding and decoding messages. Input your own constant and multiplier, then input a message to encode.

Activity: Step through the generation of Sierpinski's Triangle -- a fractal made from subdividing a triangle into four smaller triangles and cutting the middle one out. Explore number patterns in sequences and geometric properties of fractals.
