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

A denominator is the number of parts a whole is divided into

Standards CCSS.MATH.CONTENT.4.NF.B.3.CAdd and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction. Summary Now that you understand what a fraction is, what’s a numerator and what’s a denominator, you can start doing operations with fractions.

Standards Apply and extend previous understandings of multiplication and division. CCSS.MATH.CONTENT.5.NF.B.3Interpret a fraction as division of the numerator by the denominator (a/b = a รท b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.  Visualizing the

Standards Analyze proportional relationships and use them to solve real-world and mathematical problems. CCSS.Math.Content.7.EE.B.3Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess

One-half is one of two equal parts

One half means it’s fair Who doesn’t want life to be fair? Learning fractions? Start with the most basic – dividing a whole into two equal parts. Equal is the key point emphasized here. It’s not enough to be in two parts, you need two equal parts. Fractions are more than pizza I like this

Video: When is a Fraction the Same as One?

When first learning fractions, I’ve found most students benefit from lots and lots of examples. It’s fine to teach rules and procedures, which I do, but I also try to show that rule applied in many different contexts. Watch this video for many examples of how N/N = 1 . Whether it is one trip,

Video: Math Terms

Knowing your math terms is important. Students asked to find the quotient may not get the right answer not because of an inability to divide 28 by 4 but rather because they don’t know what the word ‘quotient’ means. This video goes over the terms for addition, subtraction and multiplication. This video is featured in

Problem-solving strategy : Build a model

Video: Build A Model

There’s more than one way to solve a problem, which is why we have a whole series of videos teaching problem-solving. One problem-solving strategy: build a model A model can be visual, as shown in this video. There’s also nothing wrong with a physical model, say, actually putting a dozen books in a box. After
