Students are introduced to convergence of sequences based on averaging previous terms in the sequence. The power of the "fill-down" function in spreadsheets is exploited. By using various starting numbers, and inferring the limit, students are encouraged to make generalizations of formulae for the convergence of sequences using arbitrary starting numbers.

Students prepare for the calculus concepts of limits by examining sequences that converge and diverge. By using an Excel program that generates sequences, students manipulate the starting number, multiplier and add-on values, and examine both the numerical and graphical representations of the sequence.

Students are introduced to the concept of convergent infinite series using a recursive geometric construction. They explore the concept of a convergent infinte series using partial sums. Students use formal calculations, visualizations, pattern discovery and recursion. They are asked to investigate numerically and visually the sums of infinite series. Full Review »

Students identify and distinguish between converging and diverging lenses. They also identify and distinguish between real and virtual images and construct ray diagrams that show the positions of images formed by lenses. Finally, students explain the cases of near-sightedness, farsightedness, and astigmatism. Full Review »
