A. Remove the shape you have just drawn by cutting

along the solid black lines. You’ll need to make three

additional cuts along segments JK, EL, and QZ to free

up some flaps and cube faces.

B. Fold the paper lengthwise along the four parallel

dotted lines to form the body of the cube. Tape

together the two halves of the smiley face, one on

a small flap and the other on a cube face, to hold

the cube together.

C. Fold the four remaining flaps in place, two on

2. Count the number of lines you drew that were 1 cm

each of the remaining sides, and seal the cube

by folding down the two final cube faces and

the same for lines that were 2 cm long, 3 cm long,

taping them in place. The tape allows the box to

3. The pie chart on the right is divided into 24 segments.

Each segment represents one of the 24 lines you

drew when connecting the dots. Choose a color to

represent each length that you drew. On the pie chart,

use that color to shade in the number of segments

that corresponds to the number of lines drawn for

each length. Create a legend that explains what each

color represents.

4. Count the number of segments you shaded in for

each color. Divide that number by 24 to give you the

percentage of segments represented in the pie chart.
