Divide children into convenient groups. Provide them match sticks, 50 each. Ask them to form the letter "Z" using sticks and keep 2 sticks below "z" as stem. In the next step let them form 2 "z"s and keep 2 sticks below them as stem. Further let them form 3 "Z"s and keep 2 sticks below them as stem. Now initiate the discussion.
 
−
Discussion Questions: Can you find any pattern between the number of sticks used to form the number of "Z"s and the number of sticks used to make mounting stems. Facilatate children to discover the pattern 3n+2. It is the right time to introduce the term "constant" In this case it is 2. It is also time to introduce the term "coefficient". In this case coefficient of n is 3.

Teaching Outlines

Concept #1 Algebraic thinking - Abstraction

Learning objectives

  1. To make meaning from patterns
  2. Able to extend patterns
  3. Able to state observed pattern in generalized terms
  4. Generalization; and stating in algebraic terms
  5. Algebraic variables can be “x” or “y” or “a” of “b”
  6. Combining algebraic terms – commutative and distributive properties
  7. Making simple expressions (addition, subtraction of multiple algebraic terms)
  8. Introduction to terminology called monomial, binomial, etc.
