Welcome to Mathnasium’s Math Tricks series. Students are often taught that division is the opposite of multiplication, and therefore should rely on their multiplication facts to divide; this can be difficult when the number to divide by (the divisor) extends beyond these facts. Today we are using number sense to divide, when the divisor is a power of two.

Summer is the time for road trips, backyard BBQs, days at the beach and … math? That’s right! It’s important for students to make math a part of their summer so they don’t lose what they’ve learned during the school year. On average, children lose 2-3 months of math skills during the summer months.

Welcome to Mathnasium’s Math Tricks series. Today we are comparing fractions that have the same numerators but have different denominators (the total number of equal parts in the whole).

When we compare fractions with the same numerators, we compare the same number of parts; however, the wholes may be divided into a different number of parts.
