Teaching Outlines

Concept #1 - Introduction to quadratic equations

An equation of the form ax^2+bx+c = 0 where ≠ 0 and a, b, c belongs to R.

Learning objectives

converting verbal statement into equations.

Notes for teachers

These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.

Activities

• Pupils will be encouraged to use their own informal methods before being introduced to formal solution procedures. • We will revisit the concept (meaning) of the solution of an equation. The number of solutions of an equation (no solution; 1 solution, 2 solutions or many solutions) will be dripped. • Out of this we will extract the notion of a quadratic equation, so as to distinguish it from linear and other equations.

  1. Activity No #1 introduction to quadratic equation

-A gardener wants his field to have an interesting geometrical appearance. So, he decides upon the following rules for his flowerbeds: 1.They must all be rectangular. 2.Their perimeters and areas must be the same.

a) How many different flowerbeds can the gardener make if one of the sides is 3 units less than the other side as shown in the diagram below:
