Understanding the Five D Process

The video tutorial introduces the 5D process, a problem-solving tool for organizing information and solving word problems. It uses a scalene triangle example to demonstrate the process, which includes describing, defining, doing, deciding, and declaring. The tutorial emphasizes the importance of identifying key information, defining variables, and checking solutions. The final step involves writing the solution in a complete sentence.

What is the primary purpose of the Five D Process?

• To draw geometric shapes

• To organize information and solve complex word problems

• To memorize mathematical formulas

• To calculate the area of triangles

What type of triangle is used in the example problem?

• Equilateral triangle

• Isosceles triangle

• Right triangle

• Scalene triangle

How much longer is the medium side compared to the shortest side in the triangle problem?

• 5 centimeters

• 7 centimeters

• 12 centimeters

• 10 centimeters

What is the total perimeter of the triangle in the problem?

• 30 centimeters

• 45 centimeters

• 35 centimeters

• 39 centimeters

Why is drawing a diagram helpful in solving the triangle problem?

• It makes the problem look more complex

• It provides an exact solution

• It helps visualize the relationships between the sides

• It is required for all math problems

What is the first step in the Five D Process?

• Describe

• Define

• Decide

• Declare

In the Define step, what is the expression for the medium side of the triangle?

• Short + 5

• Short + 7

• Short + 10

• Short + 12

What is the expression for the longest side of the triangle?

• 2 times the medium side

• 3 times the medium side

• 2 times the shortest side

• 3 times the shortest side

What method is used to find the correct side lengths of the triangle?

• Graphing

• Trial and error

• Using a calculator

• Guessing

If the shortest side is guessed to be 5 cm, what is the calculated perimeter?

• 39 cm

• 30 cm

• 35 cm

• 27 cm
