Solve the 2nd Layer

Thinking skills

The beginner who Memorizes the algorithms can solve the cube in less than 2 minutes.

The solver will Understand the state of the cube, what piece needs to go where, and Remember the algorithms to place it.

With lots of practice, Muscle Memory takes over.

Practice Standards

Mathematical Practice Standards (Common Core)

1. Make sense of problems & persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments & critique reasoning …. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning.

The Possibilities

Mosaics Building and

Designing

Mosaic Building

Mosaic Building

A beginning student will: learn about pixilation learn how we see color solve one face only learn organization be creative

Mosaic Building

Mosaic Designing

Making a template with graph paper, a sketch, and crayons.

Mosaic Designing

Advanced Students Art Endeavor Collaboration New Technology using GIMP Photoshop 2

Mosaic Design Contest

K-12 Mosaic Design Competition • Student(s) create original Art or a Photograph • Convert it to a Rubik’s Mosaic • Build and then Photograph the Mosaic • Send in the picture by April 7, 2017 • Voting will be done via the You CAN Do the Cube Facebook page.

The Possibilities

Speed Cubing

Speed Cubing

Motivated solvers will learn different beginner methods and then the Fridrich Method: CFOP: C - white Cross, F2L - First 2 Layers OLL – Orient Last Layer PLL – Permute Last Layer

An F2L example

Speed Cubing

The motivated solver will Memorize many algorithms Learn to recognize patterns Learn efficient use of fingers.

Thinking skills

More advanced students will learn to

Analyze the speed benefits of different algorithms and

Evaluate which ones they will use. Eventually they will

Create new algorithms that work better for them depending on the situation.

A Last Layer Concatenation

Thinking skills

With anticipating the next move and practice, a cuber can solve in less than 30 seconds. A solver learns: Sequencing Visualizing Spatial Relationships Perseverance Focus Self-direction Fast Solve

The Possibilities

School Competitions

School Competitions

Students learn: How to use Timer Cooperation Humility Team Spirit Fortitude

the Timer

Team Competitions

Solo Competitions

Competitions

“They are a

competitive bunch

and had accepted

the challenge. The

team and most of

the individual

competitors had

their best time at

the competition and

felt a true sense of

accomplishment.”

Hosting a Competition

Learn: To be Welcoming Organization Responsibility To Lead
