## Subtracting fractions with common denominators

Subtracting fractions with common denominators can be made simple. Just tell your students to follow the two steps below. We’ve also included some powerpoint and PDF files with examples in English and Spanish. If you come to this site often, you know we LOVE examples for teaching math. 3 simple steps to subtracting fractions with…

## Adding and Subtracting fractions with a Common Denominator: Multi-step problems

Students often struggle with multi-step problems for a lot of reasons. In my experience, the most common one is they stop too soon. For example, in the first lesson below, the student may add up the fractions of the rice gathered by each of the two sisters and stop there. However, the question asks, “How…

## Converting a fraction to equal 1

Converting a fraction to equal 1 To follow up our lesson plans on introducing fractions and teaching equivalent fractions, we want to talk about converting fractions to a whole number. The simplest case to start converting to whole numbers is converting a fraction to equal 1 This presentation gives several examples of when a fraction…

## Equivalent Fractions: Lesson Plan

Begin the lesson with a definition Equivalent fractions are different fractions that name the same number. The numerator and the denominator of a fraction must be multiplied by the same nonzero whole number in order to have equivalent fractions. The presentations and videos below provide multiple explanations and examples. NOTE: This lesson plans follows the lesson on Introducing Fractions. If…

## Introducing Fractions: Lesson Plan

STANDARD: Understand a fraction a/b with a > 1 as a sum of fractions 1/b. Before you jump into teaching how to add, subtract, multiply or divide fractions, it’s best to take some time to be sure your students understand what a fraction is. Today’s lesson starts with four videos that explain what exactly IS a fraction. Would you…

## Adding Fractions with Like Denominators

Now that you understand what a fraction is, what’s a numerator and what’s a denominator, you can start doing operations with fractions. The easiest place to start is in adding fractions with like denominators. Some people also call these ‘common denominators’. This video comes from our game, Fish Lake. You can get it here. In…
