# Compare Fractions, Decimals, and Percents on your Phone or Tablet with K12 Equivalence Tiles

### Compare Fractions, Decimals, and Percents on your Phone or Tablet

• Is 1/2 bigger than 33%?
• Are 0.75 and 3/4 the same?
• How many times does 1/4 go into 1?
• Which is bigger: 1/6 + 1/6 or 3/12?

Did you feel your brain working in overdrive to answer any of these questions? If so, you’re not alone.

Students from elementary to high school work with fractions, decimals, and percents every day. But research shows that students and even adults often struggle with understanding how to compare these rational numbers and use them to perform operations.

K12 Equivalence Tiles, our latest mobile app for Apple and Android,  is here to help. K12 Equivalence Tiles lets you compare the values of fractions, decimals, and percents up to 1 by using draggable tiles of varying values.This app is not a calculator. It is a tool to help students explore the crucial concept of rational number equivalencefor example, that  0.5, ½, 50% are all equal. This flexible tool also allows students to visually perform simple operations like addition, subtraction, comparison, and ordering.This app was made for students in grades 4 and 5, but we think anyone, including elementary school students to high school students working with fractions, decimals, or percents, could benefit from it. K12 Equivalence Tiles is based on an activity created for our Math+ Yellow (5th grade) course and directly aligns with Common Core Math Standards (3.NF.1, 3.NF.2, 3.NF.3, 4.NF.2, 4.NF.3, 4.NF.5, 4.NF.6, 4.NF.7, and more).
