# Activity - Introduction to abstraction

## Estimated Time

15 minutes

## Materials/ Resources needed

Open space, match sticks, blackboard

## Prerequisites/Instructions, if any

## Multimedia resources

## Website interactives/ links/ simulations/ Geogebra Applets

## Process (How to do the activity)

Ask children to make the letter "Z" from sticks. Each group to make as many Z as possible within 5 minutes.

## Developmental Questions (What 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 (Questions for assessment of the child)

- 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
