Learning objectives

 * 1) To make meaning from patterns
 * 2) Able to extend patterns
 * 3) Able to state observed pattern in generalized terms

Notes for teachers
Abstraction is generalizing the thinking. So here will focus on activities to build skills of generalization.

Activity No #
Open space, match sticks, blackboard Ask children to make the letter "Z" from sticks. Each group to make as many Z as possible within 5 minutes. Discussion questions Outcome: 3n sticks are required to form "Z" n-times. Children observe the variation in number of sticks when number of "z"s is increased /decreased. The discussion has ended up with children generalizing the pattern they observed. Outcome: The number of matchstick is a variable and will depend on number of "Z"
 * Estimated Time - 15 minutes
 * Materials/ Resources needed
 * Prerequisites/Instructions, if any
 * Multimedia resources
 * Website interactives/ links/ / Geogebra Applets
 * Process/ Developmental Questions
 * 1) How many sticks were needed for 1 "Z"?
 * 2) How many sticks were needed for 2 "Z"?
 * 3) How many sticks were needed for n "Z"?
 * 4) Children have you noticed any relationship between the number of "Z"s formed and the number of sticks used to form the letter "Z"?
 * 1) Children have you noticed any relationship between the number of "Z"s formed and the number of sticks used to form the letter "Z"?
 * 1) The number of matchstick depended on what?
 * Evaluation
 * 1) Ask children to make matchstick patterns for other letters, like "F", "A", "W"
 * 2) Make patterns of 1Z, 2Z, 3Z, 4Z and ask children to generalize patterns

Match sticks/sticks and black board Children have understood the variation of data and are able to generalise the pattern

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.
