Each group to make as many Z as possible within 5 minutes. − '''Discussion questions''' − #How many sticks were needed for 1 "Z"? − #How many sticks were needed for 2 "Z"? − #.... − #How many sticks were needed for n "Z"? − #Children have you noticed any relationship between the number of "Z"s formed and the number of sticks used to form the letter "Z"? − 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. − #The number of matchstick depended on what? − Outcome: The number of matchstick is a variable and will depend on number of "Z" − *Evaluation − #Ask children to make matchstick patterns for other letters, like "F", "A", "W" − #Make patterns of 1Z, 2Z, 3Z, 4Z and ask children to generalize patterns − *Question Corner −

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