Prime Formations (Identifying Primes)

Updated: Sep 25, 2022

In this activity about 20 beads are distributed to each team/learner. Beads are soldiers. For each announced number, that number of beads need to be arranged in a formation [non single column formation]. Any number that cannot be arranged in a formation is a Prime number. The team that identifies a Prime number first gets a point. The team with most points at the end wins.
