The document contains 6 math or geometry word problems: comparing shaded and non-shaded regions; dividing a pentagon into identical parts; organizing circles into rows; counting 30-60-90 triangles; finding prime numbers to inscribe in circles; and a quote about persevering despite failures being close to success.

1. Region
Compare the area of the
non-shaded region with the
area of the shaded region.
What is the difference between
the two areas?

2. Dissection
A. Divide the pentagon
into three identical parts.
B. Divide the pentagon
into eight identical parts.

3. Organizing circles
We have the twelve circles of the figure.
A. Organize them into four rows with four circles in each row.
B. Organize them into six rows with four circles in each row.

4. Counter

5. Prime numbers
Find four consecutive prime numbers such that when they
are inscribed in the circles the number in each segment is equal
to the sum of the numbers in the circles that join them.

6. Primos
Many of life's failures are people who
did not realize how close they were
to success when they gave up.
