Activity - Name of Activity

Objective

To introduce generalization

Estimated Time

20 minutes

Materials/ Resources needed

Match sticks/sticks and black board

Prerequisites/Instructions, if any

Multimedia resources

Website interactives/ links/ simulations/ Geogebra Applets

Process (How to do the activity)

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.

Developmental Questions (What discussion questions)

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.

Evaluation (Questions for assessment of the child)
