Relationships and Change - Week 42 - Lesson 1 - Adding and Subtracting Fractions and Converting Improper Fractions

Starter:

Simplify the following fractions:

a. 4/6

b. 6/9

c. 9/12

d. 13/169

e. 12/132

f. 42/63

g. 24/32

h. 25/75

Lesson:

Key Words: equivalent, numerator, denominator, mixed number, improper fraction, least common multiple

• Review fraction vocabulary: equivalent fraction, numerator, denominator, mixed numbers, improper fractions (have students write down these words and then turn and talk to try and come up with definitions and number examples of each)

• Use this worksheet to review fractions with visuals (look at the images and determine the fraction for each image) → you can just project it on the whiteboard but can make copies if you feel your class needs support

• Introduce adding fractions:

• Show sample problem: 2/4 + 1/4 =  

• Explain to students that when adding fractions we only add the numerators and the denominators stay the same

• Give students an example that adds up to an improper fraction: 3/5 + 4/5 =

• Ask students to solve this problem and see if they know how to change the improper fraction into a mixed number

• Introduce subtracting fractions:

• Show sample problem: 6/8 - 2/8 =

• When subtracting we only subtract the numerators

Work in Class:

• Textbook pg. 231 and 232 (work in partners and discuss answers)

Support:

• Adding fractions: adding improper and change to simplest form

Extension:

• Extension: pg. 232, Q. 11 - 14.

• Challenge: Have students complete these word problems with fractions (you can also use these throughout the week to give students an additional challenge)

Conclusion:

Conclusion: Ask students to write down 3 examples of where they can see and find fractions in their everyday lives. Have them share these with a partner and then with the whole class. Some examples could include: in recipes, money, splitting bills, pizza, etc.
