The 2-5-8 (or 20-50-80) Menu is a similar idea to the challenge list. It is much smaller and limited to three areas of thinking for the students. The students make a plan to get 10 points total.
I love this one because students who have a hard time making a decision don't have as many choices, but you still get them to the meat of the content.
