Decimal Lesson Plans

  • A Model Project - This activity is a concrete way to introduce students to equivalent forms of fractions and decimals. The student constructs models to represent a fraction or a decimal.
  • Bargain Town, USA - Designed to follow your instructions about converting number forms, this lesson is a real-world application of the relationship between fractions, decimals, and percents.
  • Base It - To expose students to number systems other than the decimal system and explain why we need to know these systems (binary: electronics and computers; octal and hexadecimal: flight test, computers).
  1. Adding and Subtracting Decimals - Consider the size of a decimal prior to developing approaches to finding exact decimal sums or differences.
  2. Better than Average - Students use baseball cards to understand averages, decimals to thousandths, and the real-world use of math.
  3. Compare and Order Fraction and Decimal Equivalence - As students enter the room they will be handed a sticky note that will have a fraction or decimal number written on it.
  4. Cuisenaire Chefs - Students become Cuisenaire Chefs as they mix and toss Cuisenaire rods to recreate recipes. This hands-on activity gives students a chance to identify the value of fractions at an introductory level.
  5. Decimals Are Brutal!
  6. Decimals Make Cents - Look out real world, here we come! Due to new jobs, pay increases, taxes, money in the bank, and opportunities to spend, spend, spend, students learn there is no way to avoid working with decimals in making life "centsable"!
  7. Does the Decimal Point Really Make a Difference? - What's the problem with cheeseburgers advertised for .99 cents each or colas for .89 cents each? Students study the decimal dilemma and discover major math mistakes in the real world.
  8. Doing Dewey - Doing Dewey reinforces the Dewey Decimal Classification System. Students will apply their basic understanding of Dewey decimal classification to the process of book organization.
  9. Everyday Math - Decimal Addition and Subtraction - The subject matter is to help students understand the various ways of adding and subtracting decimals, including modeling with base-10 blocks and using algorithms.
  10. Fractions, Decimals, and Percents - In order to help teachers with planning and teaching the lessons, each lesson is organized into the sections that include an overview, materials, time, teaching directions, teaching notes, a vignette describing the actual lesson, follow-up suggestions, and questions and discussion.
  11. Fraction and Decimal Garden - Students write fractions and decimals using unifix cube models and grid paper. They draw a garden using grid paper and label each section with the correct fraction and decimal to the tenths.
  12. Fraction and Decimal Ordering - Students learn to order numbers in fraction and decimal form, in a critical thinking and kinesthetic fashion.
  13. Fractions, Decimals, and Percents - How do they relate and how do they differ?
  14. Fractions, Decimals, and Percents - You will also learn how to convert a fraction to a percent, or a decimal to percent and so on. Get those thinking caps on.
  15. Having Fun with Decimals - Demonstrate concepts of converting decimals to fractions.
  16. How we use decimals everyday and don't even realize it.
  17. Introduction to Decimals - They will demonstrate an understanding of the relationship between fractions and decimals by converting some basic fractions into decimal form.
  18. Jeopardy Changes It! - The students will be able to express percents as fractions and decimals, fractions as decimals and percents and decimals as percents and fractions. This will show that students understand the relationship between fractions, decimals, and percents.
  19. Making Cents of Fractions and Decimals - Students learn decimals and fractions using groups of 100 pennies. By classifying the pennies in different ways, there are an unlimited number of ways to learn fractions, decimals, and place value in money.
  20. Naming Spaces with Decimal Places! - Show them how to place the decimal in the correct place.
  21. Number Chameleon - This lesson teaches students to express a quantity in a variety of ways; to understand whether relationships among fractions, decimals, and percents are equal; and to convert a number expressed in one form to another.
  22. Perfect Places! - This lesson will help students understand the role of the decimal point and the relationship between tenths, hundredths, and thousandths.
  23. Plot That Decimal - Students work in groups to plot a set of number cards containing whole numbers and decimals on a number line.
  24. Roll a Decimal - By the roll of a die, students place digits in the place value chart to create a number having the greatest or least value possible.
  25. Round to the Nearest Tenth - To correctly round their answers to word problems involving decimals on standardized and teacher-made tests.
  26. Rounded Up - How and when do we round whole numbers and decimals?
  27. The Place Value of Decimals - Read, write and identify decimals through ten-thousandths; compare and order decimals through thousandths.
  28. When Do You Use: Fractions, Decimals, and Percents?
