*Click to open and customize your own copy of the Converting Fractions to Decimals Lesson Plan.

This lesson accompanies the BrainPOP topic Converting Fractions to Decimals, and supports the standard of using decimal notation for fractions with denominators 10 or 100. Students demonstrate understanding through a variety of projects.

Step 1: ACTIVATE PRIOR KNOWLEDGE

Ask students:

Where do you see decimals in everyday life? Where do you see fractions?
How are decimals and fractions alike?

Step 2: BUILD KNOWLEDGE

Read the description on the Converting Fractions to Decimals topic page.
Play the Movie, pausing to check for understanding.
Have students read one of the following Related Reading articles: “In Practice,” or “Personalities.” Partner them with someone who read a different article to share what they learned with each other.

Step 3: APPLY and ASSESS

Students take the Converting Fractions to Decimals Quiz, applying essential literacy skills while demonstrating what they learned about this topic.

Step 4: DEEPEN and EXTEND

Students express what they learned about converting fractions to decimals while practicing essential literacy skills with one or more of the following activities. Differentiate by assigning ones that meet individual student needs.

Make-a-Movie: Produce a news report about a race where athlete A ran .2 of the race in five minutes and athlete B 75/100 of the race in that time. Explain who is in the lead, and how you know.
Make-a-Map: Identify the relationship between fractions and decimals. Outline the steps to convert between the two.
Creative Coding: Code a math problem that involves converting a fraction into a decimal, and challenge a classmate to solve.

With guidance and support from adults, use technology to produce and publish writing (using keyboarding skills) as well as to interact and collaborate with others.

Grade: 04

CCSS.ELA-Literacy.W.4.9b

Apply grade 4 Reading standards to informational texts (e.g., “Explain how an author uses reasons and evidence to support particular points in a text”).

Grade: 05

CCSS.ELA-Literacy.W.5.9b

Apply grade 5 Reading standards to informational texts (e.g., “Explain how an author uses reasons and evidence to support particular points in a text, identifying which reasons and evidence support which point[s]”).

Grade: 06

CCSS.ELA-Literacy.W.6.9b

Apply grade 6 Reading standards to literary nonfiction (e.g., “Trace and evaluate the argument and specific claims in a text, distinguishing claims that are supported by reasons and evidence from claims that are not”).

Grade: 07

CCSS.ELA-Literacy.W.7.9b

Grade: 04

CCSS.Math.Content.4.NF.C.6

Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.

Grade: 07

CCSS.Math.Content.7.EE.B.3

Solve 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 the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.

Grade: 07

CCSS.Math.Content.7.NS.A.2d

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.
