Mental Multiplication and Division: Primes and Factors
Take a step closer to becoming master manipulators of numbers! In this lesson, children will identify the factors of some two-digit numbers, then identify which of these have some special qualities. They may identify two-digit numbers whose factors, when totalled, equal more than the original number. Some children may also find all of the prime factors of some two-digit numbers by drawing factor trees.
