BENCHMARK FRACTIONS CHART HOW TO
For example, when students only know how to compare fractions with common denominators or with the butterfly method, I ask them to compare 433/2,346 with 433/297,862. One of my favorite things about teaching is designing questions that “break” certain methods. It has 3 steps outlined with a color coding to match the examples to help students see the correlation. The steps include writing the decimal in word form, finding the denominator, and finding the numerator. At the risk of over-self-promotion, I figured I would share that here because it might be helpful for others who aren’t familiar with these strategies: This anchor chart is perfect for introducing how to use decimal notion for fractions with denominators of 10 and 100.
In graduate school, I wrote a blog post on strategies for comparing fractions to help some of my classmates who only knew the butterfly method. Instead I try to link their understanding to the multiplicative identity (2/3 * 1 = 2/3 and 2/3 * 3/3 = 6/9 so 2/3 = 6/9). Be sure to grab these free benchmark fractions worksheets and anchor chart I hope this post helps you see why benchmark fractions are a great strategy for comparing and ordering fractions If you want to save time, you can grab my benchmark fractions bundle. It’s certainly not the worst phrase, but I still find myself avoiding it. The ability to determine appropriate benchmarks for fractions which are categorized with the benchmarks between 0, 1/2, and 1 using such terms as greater than, less than or equal to another fraction can strengthen the understanding of fractions. One phrase I try to avoid with my students is that “whatever you do to the numerator, you do to the denominator.” I find that rule expires once students start operating with fractions. They help students study equivalent fractions. This is such an awesome resource for teachers and parents too! Thank you so much for the time you put into making it. A benchmark fraction chart is a simple visual that allows students to see where a fraction lies on a number line when compared to a whole.
