AI-written overview

What is it?

Reinforcing numeracy through a Sorting Network is part of a CS Unplugged unit about sorting. You walk through a path drawn on the ground, comparing numbers with other people, until everyone ends up in order.

Is it for me?

It is for children about 5-7 and up who like moving around and working in a team, with a grown-up or teacher. It is a Beginner activity and needs chalk or tape and some space.

Grown-ups: only one team walks the path at a time, so give the watchers a job, like checking the results.

How to start

  1. Draw the sorting path on the ground with chalk or tape.
  2. Give six people a number each and let them walk through, comparing at each meeting.
  3. Check if everyone ended up in order, then try new numbers.

How much time?

Most lessons take 30 to 45 minutes. Plan about 15 minutes for a session. (estimate)

15 min per session 2 sessions estimate

A plan you can follow

  1. Day 1 45 min Walk through the path with six numbers.
  2. Day 2 30 min Try different cards, such as bigger numbers.
  3. Week 1 30 min Sort other things, like heights.
  4. Week 2 30 min Draw your own bigger network.
