This is an engaging and visual way to introduce multiplication and the concepts of factors, multiples, primes, composites and MORE! Students build arrays for the numbers 1–25 and look for patterns and characteristics that help them learn to recognize multiples. Directed questions also help them to learn to identify primes and composites. Square numbers, factor rich numbers, and perfect numbers are included for more advanced students.
Extensions allow you to take the lesson to a multi-day in depth exploration of 1–3 days that will embed these critical multiplication concepts and even help students represent their learning graphically.
All answer keys and activity masters are included.
