GOAL:The WHITE Corners

The goal of this stage is to get the WHITE corners on the UP face with all the with the TOP row of each face matching the center piece.

¼ Turns

• Inverted means opposite• By inverting a move, the move can be undone

• The word “row” refers to an entire row that moves. “Rows” are three-dimensional.

Rows and Faces

• The word “refers” to the flat outer area of the row. “Faces” are two-dimensional.

REVIEW FROM THE WHITE CROSS

• Make sure the WHITE Face is UP• Find a WHITE edge• Twist the row of the cube that has the WHITE edge

until the WHITE edge is on the bottom row• Twist he DOWN Face “D” ¼ turn

• Put the row you moved back where it was originally• Put the WHITE edge directly below the matching

colored center piece• Make two “F” ¼ turns, so the WHITE edge is on the

TOP row

• Repeat all the steps for each WHITE edge. • If the pattern is not WHITE, WHITE, use the

sequence to correct the pattern:

To get the WHITE edges matched with the correct faces:

ALGORITHM

An algorithm is a set of rules or set of steps that we use to solve math problems.





Lesson Extension


To get the WHITE/BLUE/RED corner is correct position:

• Position the WHITE center piece facing up so that the WHITE face is UP

• Find the WHITE/BLUE/RED corner• If the corner colors do not match their faces, then:

– If the WHITE/BLUE/RED edge is not already on the bottom row of the cube) Twist the row of the cube that has the WHITE/BLUE/RED edge “L”, “Ri”, “F”, “Fi”, “B”, or “Bi” until the WHITE/BLUE/RED corner is on the BOTTOM row of the cube.

• Twist the DOWN Face a “D” ¼ turn• Be sure to put the row that was moved back to its

original place before moving the DOWN face again.• Now position the WHITE/BLUE/RED corner

directly below the top row corner piece where the WHITE/BLUE/RED corner should be.

• Position the cube so that the WHITE/BLUE/RED corner is at the RIGHT/FRONT corner of the cube.





Lesson Extension


To get the WHITE/BLUE/RED corner is correct position:

• To get the corner to the TOP row with matching color faces, use your RIGHT hand and the following algorithm:

• Use the algorithm: “Ri” “Di” “R” “D” repeatedly (as many times as it takes) to get the WHITE square on the UP face, the BLUE square is on the BLUE face, and the RED square is on the RED face.





Lesson Extension


To get the WHITE/BLUE/ORANGE corner is correct position:


• Find the WHITE/BLUE/ORANGE corner• If the corner colors do not match their faces, then:

– If the WHITE/BLUE/ORANGE edge is not already on the bottom row of the cube) Twist the row of the cube that has the WHITE/BLUE/ORANGE edge “L”, “Ri”, “F”, “Fi”, “B”, or “Bi” until the WHITE/BLUE/ORANGE corner is on the BOTTOM row of the cube.


original place before moving the DOWN face again.• Now position the WHITE/BLUE/ORANGE corner

directly below the top row corner piece where the WHITE/BLUE/ORANGE corner should be.

• Position the cube so that the WHITE/BLUE/ORANGE corner is at the RIGHT/FRONT corner of the cube.





Lesson Extension


To get the WHITE/BLUE/ORANGE corner is correct position:


• Use the algorithm: “Ri” “Di” “R” “D” repeatedly (as many times as it takes) to get the WHITE square on the UP face, the BLUE square is on the BLUE face, and the ORANGE square is on the ORANGE face.





Lesson Extension


To get the WHITE/GREEN/ORANGE corner is correct position:


• Find the WHITE/GREEN/ORANGE corner• If the corner colors do not match their faces, then:

– If the WHITE/GREEN/ORANGE edge is not already on the bottom row of the cube) Twist the row of the cube that has the WHITE/GREEN/ORANGE edge “L”, “Ri”, “F”, “Fi”, “B”, or “Bi” until the WHITE/GREEN/ORANGE corner is on the BOTTOM row of the cube.


original place before moving the DOWN face again.• Now position the WHITE/GREEN/ORANGE corner

directly below the top row corner piece where the WHITE/GREEN/ORANGE corner should be.

• Position the cube so that the WHITE/GREEN/ORANGE corner is at the RIGHT/FRONT corner of the cube.





Lesson Extension


To get the WHITE/GREEN/ORANGE corner is correct position:


• Use the algorithm: “Ri” “Di” “R” “D” repeatedly (as many times as it takes) to get the WHITE square on the UP face, the GREEN square is on the GREEN face, and the ORANGE square is on the ORANGE face.





Lesson Extension


To get the WHITE/GREEN/RED corner is correct position:


• Find the WHITE/GREEN/RED corner• If the corner colors do not match their faces, then:

– If the WHITE/GREEN/RED edge is not already on the bottom row of the cube) Twist the row of the cube that has the WHITE/GREEN/RED edge “L”, “Ri”, “F”, “Fi”, “B”, or “Bi” until the WHITE/GREEN/RED corner is on the BOTTOM row of the cube.


original place before moving the DOWN face again.• Now position the WHITE/GREEN/RED corner

directly below the top row corner piece where the WHITE/GREEN/RED corner should be.

• Position the cube so that the WHITE/GREEN/RED corner is at the RIGHT/FRONT corner of the cube.





Lesson Extension


To get the WHITE/GREEN/RED corner is correct position:


• Use the algorithm: “Ri” “Di” “R” “D” repeatedly (as many times as it takes) to get the WHITE square on the UP face, the GREEN square is on the GREEN face, and the RED square is on the RED face.





Lesson Extension


Troubleshooting

• If you accidentally place a white corner with the incorrect faces, reposition the WHITE corner on the BOTTOM row underneath the TOP row corner where it belongs with the matching face colors and use the algorithm

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





Lesson Extension


GOAL:The WHITE Corners

The goal of this stage is to get the WHITE corners on the UP face with all the with the TOP row of each face matching the center piece.

Examine your Rubik’s Cube.

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

REVIEW

• Position a WHITE corner on the BOTTOM row underneath the TOP row corner where it belongs with the matching face colors.

• Use the algorithm as many times as needed until the corner is correctly place.

• Repeat the steps for each corner until all four

corners are in the correct places.

To get the WHITE corners matched with the correct faces:





Lesson Extension


Lesson Extension

•Repeating the pattern or algorithm as many times as needed is similar to repeating the steps to solve a long division problem with decimals.

•In this long division problem, every number was divided by the divisor (5) and the next number in the dividend (56.34) was brought down to make a new dividend.

•When solving for the WHITE corners, every bottom corner starts the same way.

•The algorithm is used to place the corner in the correct place.

•With the next corner, the same algorithm is used to place that corner correctly.

Who produced the most expensive Rubik’s Cube? What was it called?

The most expensive Rubik’s Cube was the Masterpiece Cube, produced by Diamond Cutters International in 1995. This actual size, fully-functional cube features 225 carats of amethyst, 25 carats of rubies, and 24 carats of emeralds, all set in 18-carat gold, and was

valued at approximately 1.5 million US dollars.
