Welcome to Mathnasium’s Math Tricks series. Today we are squaring numbers ending in 0 or 5 by observing patterns and applying our number sense.

Welcome to Mathnasium’s Math Tricks series. Today we are comparing fractions using the concept of wholes and parts … in this case, finding the *missing parts *that make one whole.

Welcome to Mathnasium’s Math Tricks series. Today we are using number sense to divide statements where the *divisors* (the numbers we are dividing by) have more than two *factors* (numbers which divide evenly into the divisor). Rather than dividing a *dividend* (the number to be divided) by a challenging divisor, the trick is to break it down into smaller, more manageable parts, and then divide by each part.

Welcome to Mathnasium’s Math Tricks series. Today we are comparing fractions to the benchmark number, *one half*.

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. The trick is to cut the *original number *(the dividend) in half the *appropriate number of times* (the “power” amount).

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).

Welcome to Mathnasium’s Math Tricks series. Whether it is in statistics or the real world, we are occasionally required to count large amounts. It can be a long and tedious process to list the total number of combinations for given events. So today we are showing you how to use the *Fundamental Counting Principle *to count the number of outcomes; the trick is to multiply the number of possibilities for each event together.

Welcome to Mathnasium’s Math Tricks series. Kids commonly fear fractions when they encounter them. The goal is to group specific fractions and observe patterns. With these patterns, we can develop “tricks” to compare them. Today we are using our knowledge of the parts of a fraction to identify the biggest and smallest fractions with common denominators.

Welcome to Mathnasium’s Math Tricks series. When kids learn their multiplication facts, they often first master their five times tables. But multiplying large numbers by five can get tricky. Today we are using the fact that five is *half of ten* to multiply an even or odd number by five.
