The following is a description of how I used (for my Math Concepts II course for pre-service teachers) Robin A. Ward 's activity titled Fractions, Decimals, and Gravity.

MathGoodies Intro to Probabilities website
For my Math Concepts II course, in a classroom with a computer and projector, I used this website at an initial presentation to introduction to probabilities. Note each student was given a hard copy of the content of the website. Each topic was consistent with our textbook.

I used Emily Mason's Discovering Patterns Activity in Math Concepts I course. We were in a technology classroom. I created an Excel demonstration handout, which I discussed in class. The students worked in pairs on the activity and it was followed up by a homework assignment, called follow up on Discovering Patterns.

Simulating Basketball free-throw (Excel)
I used Lisa Petraitis and Jeff Walraven's Mathematical Investigation with Excel Activity in Math Concepts I course. We were in a technology classroom. I created an introductory handout (and short video), which I discussed in class. The students worked in pairs on the activity, but were not using the graph effectively. Instead they were simply employing trial and error, thus I created a second handout (discussed again in class) on using the graph more effectively.

Practicing Roman Numeral Addition
I used AAAmath website Addition of Roman Numerals Activity in Math Concepts I course. We were in a technology classroom. I created a handout with instructions for reaching the webpage, directions for collaborative exercise and printing the 2nd page of the website. The activity was very easy for the students; it took them much less than the 10 minutes that I allotted for the practice of 20 addition problems.
