Presenting worked solutions

Hand writing solutions onto a small screen is challenging. Here are some effective approaches.
- Pre-prepare the worked solution. Have it succinctly written out in front of you. Then take the time to write it up neatly and carefully in a way that makes it fit nicely onto the board.
- Share a whiteboard and collaboratively work up the solution with the students.
- Write up the worked solution in MSWord, then cover the text with many white rectangles, and uncover the rectangles one by one as you work through the solution.
- Write up the worked solution in LaTex, using the Beamer uncover command, then uncover the solution a little at a time as you work through it.
- Write up the solution in One Note, or handwrite and scan the solution, then use a “gradually uncover” approach to display the solution in the class. You can achieve this by covering the solution with a white rectangle that you gradually move, or remove.
Keep written solutions succinct. Don’t write more words than you need to. Save the extra words for your oral explanation.
Ensure solutions are complete. Model solutions that will get students full marks. Do not cut corners in written solutions, or omit bits.
