Here's one that will tie your brain in knots. Some of these logic puzzles will challenge even advanced high school students, but both solutions and discussion are readily available for those who struggle. There are many different puzzle types, and new content seems to appear regularly. Note, however, that the ad banner space occasionally displays content that some might not deem appropriate for school use.

tag(s): logic (163), puzzles (143)

In the Classroom

Teachers will find this one a great source for "extra point stumpers."

This site provides practice with patterns, relations, and functions through the tale of the the Tortoise and the Hare. The amount of the tortoise's head-start can be changed, then take the racers through the various stages to find out who wins! Students will enjoy predicting the winner while watching the race unfold. The instructor's section provides detailed information on standards addressed, classroom questions, and links to similar resources. There is also a link to downloadable exploration questions that can be used in conjunction with the site.

tag(s): estimation (35), functions (52), measurement (125), patterns (63)

In the Classroom

Provide students with a copy of the explorations questions to complete alone or with a partner. Use on your interactive whiteboard for a quick 5 minute filler, change the amount of the tortoise's head-start each time to offer different outcomes each time. Ask students to predict the outcome of each race before beginning, allow changes midway, and discuss what is happening to change students' opinions.
