Product Description
1. This first set of Lesson Plans for Standard 5.NF.A.1 covers the addition of fractions and mixed numbers with unlike denominators.

2. Students will add fractions by finding a common denominator. This common denominator can be found by multiplying the denominator of the first fraction by the denominator of the second fraction and is not necessarily the lowest common denominator.

3. Students will explore the associative and commutative properties of addition by breaking mixed numbers apart and then adding the parts separately. The commutative and associative properties mean that it does not matter how the numbers are grouped or in what order they are added, the sum (answer) will always be the same.

4. Students also add mixed numbers by using improper fractions.

5. Students will model both types of solutions using number lines that are provided.

6. Using a number line, students will break improper fractions into a sum of smaller fractions as a method of finding the equivalent mixed number. (Fourth Grade Standard 4.NF.B.3.B).

7. These Lesson Plans include templates that allow teachers to modify and create additional practice problems for students.
