### Planning

Lesson Plan: Fraction Kits: Subtraction Mixed Numbers with Unlike Denominators

Objectives:

Process: Students will use models to visualize subtracting fractions, and understand how the models relate to the algorithm.
Content: Students will learn how to subtract mixed numbers with unlike denominators.

Materials:

Fraction kits and math journals for each student
Student homework
Exit card

Motivator (5 minutes):

Instruct students to take out their fraction kits, math journals, and homework.

Independent practice (10 minutes):

Instruct students to use fraction kits to complete warm-up problems. Circulate and help as necessary.

Model instruction/check for understanding (40 minutes):

A. Have student volunteers explain how to complete warm up problems using magnetic fraction kits.(10 minutes)
B. Introduce the algorithm for subtracting mixed numbers (1. subtract whole number, 2. find the least common denominator of the 2 fractions, 3. find equivalent fractions of the same denominator and solve the problem). Go over selected homework problems, using both the fraction kits and the algorithms, calling on volunteers to assist.(30 minutes)

Regroup/Summarizing (5 minutes):

Have the students review the algorithm as written in their math journals

Closure (10 minutes):

Have students complete exit card.
