This week is the final hand-in week for Problems of the Week for this year. Remember to choose one of the last three that you feel is your best example of problem solving and answer the reflection and connection questions before you hand it in.

In 1994, computer scientist Clifford A. Pickover came up with the term Vampire Number to describe numbers that are “subtly hidden” from our view. This week's PoW, which is the last one of this year, asks you to try and find six of the lowest known vampire numbers. As an extra challenge, can you find any vampire numbers with more than 4 digits that have multiple fangs? And if you really want to challenge yourself, can you find any prime vampire numbers (ie. vampire numbers with fangs that are prime numbers)? Good luck and come back next fall for more Problems of the Week!
This week's problem is likely one that is up there in terms of difficulty. It requires an investigation into whether there is a relationship between the area of a quadrilateral and a second quadrilateral formed by connecting the mid-points of the sides of the first. Give it a shot and good luck!
This week's Problem of the Week will be one of the last three we do this semester. It requires your visual and spatial senses to connect randomly assorted boxes with matching triangles that are in numerical order. You must stay in the puzzle area and you cannot cross lines. Good luck!

What are PoWs?Problems of the Week are puzzles, problems and questions I give out in a 4 week cycle. The first three weeks are new problems for students to try. The fourth week is a chance for reflection and an opportunity for students to choose one of the three PoWs to hand in as a showcase of their problem solving abilities. Hand-in OutlineArchives
