GOAL:The YELLOW Cross

The goal of this stage is to get the YELLOW cross on the UP.

HORIZONTAL

Horizontal is the name that describes when a line (or row) is parallel to the horizon. When looking at the cube, a horizontal line

is parallel to the BOTTOM or TOP row of the cube

THE MIDDLE LAYER IS HORIZONTAL

HORIZONTAL LINE





Lesson Extension


VERTICAL

Vertical is the name that describes when a line (or row) is perpendicular to the horizon. When looking at the cube, a vertical

line is parallel to the RIGHT or LEFT row of the cube.

THE BLUE MIDDLE ROW IS VERTICAL

VERTICAL LINE

REVIEW fromThe Middle Layer

• Find an edge on the UP face that is NOT YELLOW on the UP or FRONT face.

• Match the FRONT face of the edge to the center piece of the same color so that there is a vertical middle line of all one color on the FRONT face of the cube.

• Look at the TOP face of the edge: • If that color belongs on the RIGHT face (clockwise) of the

cube:

• If that color belongs on the LEFT face (counter-clockwise) of the cube:

• Repeat the instructions until the horizontal middle line of each face has been solved.

• Make sure the WHITE cross remains intact each time you reposition a WHITE corner.

To get the Middle Layer:

RIGHT ANGLE

A 90 degree angle





Lesson Extension


Lesson Focus

• How many YELLOW pieces are on the YELLOW face?

• Does your YELLOW face have a YELLOW cross? • If yes, then solving for the YELLOW cross is complete.





Lesson Extension


Lesson Focus

• Does your YELLOW face have only the YELLOW center piece?

• If yes, then follow the algorithm to get the YELLOW cross:





Lesson Extension


Lesson Focus

• Does your YELLOW face have a right angle shape at one of the corners?

• If yes, face the YELLOW right angle toward the BACK LEFT corner then follow the algorithm to get the YELLOW cross:





Lesson Extension


Lesson Focus

• Does your YELLOW face have a single middle line horizontally or vertically?

• If yes, match the line so it is horizontal on the UP face, then follow the algorithm to get the YELLOW cross:





Lesson Extension


Troubleshooting

• If you are unsure about the image on your cube, or if your cube doesn’t match one of the three options exactly…

• Find the best match.

• For example: • If your YELLOW face has a YELLOW center

piece and a YELLOW edge, the most accurate match would be the single YELLOW center piece (option 1).

GOAL:The YELLOW Cross

The goal of this stage is to get the YELLOW cross on the UP.

Examine your Rubik’s Cube.

Does your Rubik’s Cube look like this? Does your Rubik’s Cube look like this?

REVIEW

• Look at the YELLOW face.• Match the YELLOW face with: • The single YELLOW center piece and follow the

algorithm:

• The YELLOW right angle corner and follow the algorithm:

• The single YELLOW line down the middle row of the YELLOW face and follow the algorithm:

To get the YELLOW Cross:





Lesson Extension


Lesson Extension

• The YELLOW cross is a symmetrical shape.

• Symmetry is when an image can be divided equally and looks the same on both sides of the division.

• When you are looking at the YELLOW face, at the cross, imagine a line drawn down the middle of the cross.

• The images on both sides of the line are the same.

• Therefore, the YELLOW cross is symmetrical.
