Description
What our Mixed Numbers, Introduction lesson plan includes
Lesson Objectives and Overview: Mixed Numbers, Introduction demonstrates the components of mixed numbers. At the end of the lesson, students will be able to understand the components of mixed numbers. Students will be also able to convert from a mixed number into an improper fraction and from an improper fraction to a mixed number. This lesson is for students in 3rd grade, 4th grade, and 5th grade.
Classroom Procedure
Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the blue box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand.
Options for Lesson
Included with this lesson is an “Options for Lesson” section that lists a number of suggestions for activities to add to the lesson or substitutions for the ones already in the lesson. One optional addition to this lesson is to write mixed numbers on paper plates and hang them throughout the classroom as a fun way for students to practice. You can also have your students play “around the world” with fraction cards or play a jeopardy game with fractions. Finally, you could have your students make their own fraction problems to color in.
Teacher Notes
The teacher notes page includes lines that you can use to add your own notes as you’re preparing for this lesson.
MIXED NUMBERS, INTRODUCTION LESSON PLAN CONTENT PAGES
Mixed Number Introduction
The Mixed Numbers, Introduction lesson plan includes one page of content. Mixed numbers are made up of two pieces, a whole number and a fraction. For example, in the mixed number 5 2/3, 5 is the whole number, 2 is the numerator of the fraction, and 3 is the denominator of the fraction.
To convert a mixed number into an improper fraction, you need to follow three steps. Improper fraction have numerators larger than their denominators.
The first step is to multiply the whole number by the denominator. The second step is to add the numerator. Finally, the third step is to place the total as the new numerator and keep the denominator.
Examples
The lesson includes two examples. For the first example, we want to convert the mixed number 3 2/5 into an improper fraction. Before starting, it can be helpful to identify the components of the mixed number: the whole number is 3, the numerator is 2, and the denominator is 5.
For the first step, we multiply the whole number by the denominator: 3 x 5 = 15. For the second step, we add the numerator: 15 + 2 = 17. Finally, for the third step, we place the total as the new numerator and keep the denominator: 17/5. Therefore, 3 2/5 converted into an improper fraction is 17/5.
The lesson closes with a second example, 2 3/8. For this mixed number, the whole number is 2, the numerator is 3, and the denominator is 8. We follow the same steps to convert it into an improper fraction. First, multiply: 2 x 8 = 16. Next, add: 16 + 3 = 19. Finally, replace the numerator and keep the denominator for a final answer of 19/8.
MIXED NUMBERS, INTRODUCTION LESSON PLAN WORKSHEETS
The Mixed Numbers, Introduction lesson plan includes four worksheets: an activity worksheet, a practice worksheet, a homework assignment, and a quiz. You can refer to the guide on the classroom procedure page to determine when to hand out each worksheet.
SCAVENGER HUNT ACTIVITY WORKSHEET
The activity worksheet asks students to find and solve problems hidden around the classroom. They will locate each letter (written both on the worksheet and on the hidden cards) and write the mixed number. Finally, they will convert the mixed numbers to improper fractions and circle the answers.
RIDDLE PRACTICE WORKSHEET
For the practice worksheet, students will convert mixed numbers to improper fractions and fill in the letters to solve the riddle.
MIXED NUMBERS HOMEWORK ASSIGNMENT
The homework assignment asks students to label the mixed number using vocabulary terms from the lesson (numerator, whole number, and denominator). They will then convert mixed numbers to improper fractions and write a mixed number to describe the picture shown on the worksheet.
QUIZ
This lesson also includes a quiz that you can use to test students’ understanding of the lesson material. For the quiz, students will solve problems by converting to an improper fraction or writing the mixed number in the box.
Worksheet Answer Keys
This lesson plan includes answer keys for the practice worksheet, the homework assignment, and the quiz. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.
