**Spectral Blaster**

##### (MathPickle, 2017)

Get your students deducing the mysterious rules that need to be satisfied in order to fire their spectral blaster. Until the four rules are discovered students should remain together as a class. Then they should go off to try to solve and explore. Here are the four rules for reference. Do not let your students see this list!

Rule 1: Equality

Rule 2: Different Pattern

Rule 3: Mirror Symmetry

Rule 4: Different Axes

MathPickle’s use of this image is legitimate as it does not interfere with the selling of the game and is for noncommercial purposes and is a part of my general commentary and critique of computer based games as opposed to board games. Parents need to get their children involved in slow, methodical problem solving. Doing this problem solving in a group rather than looking at a computer screen has social advantages. If there is one thing that parents should keep from Call of Duty and other violent shoot-em-ups – it is the violence. That can be exciting for boys… but try to move it into a slow paced strategic game like Memoir ’44.

**Standards for ****Mathematical Practice**

MathPickle puzzle and game designs engage a wide spectrum of student abilities while targeting the following Standards for Mathematical Practice:

##### MP1 Toughen up!

This is problem solving where our students develop grit and resiliency in the face of nasty, thorny problems. It is the most sought after skill for our students.

##### MP3 Work together!

This is collaborative problem solving in which students discuss their strategies to solve a problem and identify missteps in a failed solution. MathPickle recommends pairing up students for all its puzzles.

##### MP6 Be precise!

This is where our students learn to communicate using precise terminology. MathPickle encourages students not only to use the precise terms of others, but to invent and rigorously define their own terms.

##### MP7 Be observant!

One of the things that the human brain does very well is identify pattern. We sometimes do this too well and identify patterns that don't really exist.
