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.
