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
Children have understood the variation of data and are able to generalise the pattern
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.
