Educator Instructions
- Introduction (5 mins)
Begin by asking students if they've ever heard of improper fractions or mixed numbers. Briefly discuss what fractions are. Introduce the idea that some fractions can be bigger than one whole. Explain we are going to watch a fun video that will show us all about it. - Video Viewing (5 mins)
Play the 'Mixed Numbers Song | Converting Improper Fractions and Mixed Numbers' video by NUMBEROCK. Encourage students to listen carefully to the lyrics. - Discussion (10 mins)
After the video, discuss the key concepts presented. Ask students what they learned from the song. Review the definitions of improper fractions (numerator greater than or equal to the denominator) and mixed numbers (whole number and a fraction). Go over the steps of converting improper fractions to mixed numbers and vice-versa, using visual aids like circles or fraction bars. - Practice Problems (15 mins)
Work through several examples of converting improper fractions to mixed numbers and vice-versa as a class. Start with easier examples and gradually increase the difficulty. Use manipulatives like fraction circles or drawings to help students visualize the conversions. - Independent Practice (10 mins)
Have students work individually on practice problems. Provide a worksheet with a variety of conversions to complete. Circulate to assist students as needed.
Interactive Exercises
- Fraction Circle Conversions
Provide students with fraction circles or pre-drawn circles divided into different fractions (halves, thirds, fourths, etc.). Have them represent improper fractions using multiple circles and then convert them to mixed numbers by grouping the whole circles. Repeat the process in reverse for converting mixed numbers to improper fractions. - Number Line Hop
Create a number line with fractions marked (e.g., halves, thirds, fourths). Give students improper fractions and have them 'hop' along the number line to find the corresponding mixed number. For example, for 5/2, they would hop 2/2 (1 whole), another 2/2 (another whole), and then 1/2, landing on 2 1/2.
