1 g
This item is only available to Club Directors


 1. Have the Math Skills II honor.

2. Solve the following operations using the traditional algorithm: a. 641 + 135 b. 845 - 124 c. 34 x 125 d. 856 ÷ 24

3. Identify and classify the numerical sets.

4. Demonstrate the ability to solve the following equations: a. 2x - 10 = -4x + 14 b. 18x - 43 = 65 c. 23x - 16 = 14 - 17x d. 10y - 5(1 + y) = 3(2y - 2) - 20 e. x(x + 4) + x(x + 2) = 2x² + 12 f. (x - 5) / 10 + (1 - 2x) / 5 = (3-x) / 4 g. 4x(x + 6) - x² = 5x²

5. Demonstrate the ability to solve the following products: a. (x + 3y) b. (a5 + 2bc)² c. (3x + y²)² d. (1 + 5m)(1 - 5m) e. (ab - c)² f. (m - 1)³ g. (a³ - b³) (a³ + b³)

6. Calculate the area of the following figures:

7. In the Orienteering honor, the Pathfinder must have knowledge of angles to know how to use cartographic charts and to use a compass. Demonstrate the ability to convert angles to minutes, minutes to seconds, showing three practical examples.

8. In the Pioneering honor, we learned to build camp furniture, which has a whole mathematical relationship. Design and present some camp furniture where geometric shapes appear and classify each one. Cite three examples.

9. Present a poster showing ten practical examples of geometric figures used in a daily routine. It can be as cutouts, photos or design.

10. Demonstrate the ability to solve the following proportion problems: a. At 60 km/h I travel between two cities in two hours. Traveling at 80 km/h, what is the estimated time to travel this route? b. At an average of 90 km/h, I can make a journey in three hours. To make this journey in just two hours, what should my average speed be? c. If 20 men working for 20 days build 500 meters of a wall, how many men will it take to build 1000 meters more of this wall in 30 days?

11. Demonstrate the ability to solve problem situations involving equations: a. I have the following choice: I buy 20 units of a product with all the money I have, or buy only 14 units of a project with all the money I have, or buy only 14 units and I still have $15.00 in change. What is the unit value of this product? b. What is the root of the equation 7x - 2 = -4x + 5? c. If I add 8 to the amount of toy cars I own, I will have the same amount of cars as my brother if, of the 28 that he owns, the amount that I own is subtracted. How many toy cars do I have?
