The Lesson Plan

Introduce the lesson:
Define the meaning of ratios and proportions and present examples.  

Teach the lesson:
Present examples to the class. How many males and females are in the class? Introduce the proportion equation. Explain cross multiplication and how the equation balances.
   i.e. 2/6 = x/18     x=6

Practice the lesson: 
Students are given several examples of problems related to real world activities. The teachers should observe each student to make sure they are applying the proper concepts. Example: If we bring to class pizza cut into 8 slices and we have 12 students, how many pizzas we need if each student eats 3 slices?
x/12 students = 3 slices/one student    x=12*3= (36 slices)
                                                                         = 5 pizzas

Assess the lesson:
Introduce feedback given to students working on the problems

Apply the lesson to the real world:
Students can apply this lesson to any other real-world situation.
