Karyn Hodgens, Elementary Mathematics Specialist, shows how simple objects like tiles, stickers, rubber stamps, dice, and graph paper help teach students important concepts in number theory: factors, primes, composites, and square numbers...not to mention the great reinforcement of multiplication facts.

Great resource where teachers are able to get a visual of how to introduce a lesson. This information is great to share with primary educators with the utilization of manipulatives.
