Adding and Subtracting Fraction

Adding and Subtracting Fraction


This educational poster provides students with quick "shortcut" tips for simplifying fractions. It focuses on three common scenarios where fractions can be simplified in an easier, faster way.


The poster features:


A section on even numbers in the numerator and denominator, showing how to divide by 2

A section on numbers ending in 5 or 0, showing how to divide by 5

A section on numbers ending in 0, showing how to divide by 10

Worked examples demonstrating each shortcut scenario

This math poster acts as a helpful visual aid to reinforce simplifying fractions. It can be displayed in the classroom as an easy reference for students. The shortcuts allow students to simplify fractions more efficiently.


An excellent addition to elementary and middle school math classrooms when teaching simplifying fractions. This poster provides useful tips students can apply to reduce fractions to their simplest forms quickly. An engaging supplementary resource to build math skills! As with all of our resources, it is customizable so you can tailor this resource for your class.

    Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, 𝘢/𝘣 + 𝘤/𝘥 = (𝘢𝘥 + 𝘣𝘤)/𝘣𝘥.)


    Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.


    Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷ (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (𝘢/𝘣) ÷ (𝘤/𝘥) = 𝘢𝘥/𝘣𝘤.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?


    Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.


    Solve real-world and mathematical problems involving the four operations with rational numbers.


    Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.
