How to Beat the Summer Slide
Did you know that children typically lose 2-3 months of math skills over the summer months? Here are ways to avoid the summer slide in your child's math development.
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.
To compare fractions, we can turn to a few tricks we’ve covered in our series: comparing common denominators or same numerators, or comparing the fractions to the benchmark of one half. When these tricks do not apply, we can compare fractions to the benchmarks one whole, or zero. The trick is to find the “missing pieces” (or parts), of each fraction that make one whole, and compare these pieces — the fraction with the smallest missing piece is bigger (i.e., closer to one whole), or conversely, the fraction with the larger missing piece is smaller (i.e., closer to zero).
Follow the example below to identify the fraction with the biggest value.
Step 1: Identify what you are looking for. You love pie and so you want the biggest piece.
Step 2: Identify the number of pieces you are comparing. You are comparing one missing piece from each pie:
Step 3: Compare the missing pieces. Seventeenths are smaller than sevenths, thirteenths, and fourteenths.
Answer: You want of a pie, since is bigger than
Now, with this strategy, you are ready to compare fractions by finding the missing piece that makes one whole. Click here for more practice problems, then check your answers here.
