Introduction

Math Skill/Concept: Adding Fractions with Mixed Numbers (Like Denominators) using concrete materials.

Prerequisite Skills:

• Ability to identify concrete representations of fractional parts and wholes.
• Ability to add common fractions with like denominators.

Learning Objectives:

1) Combine two sets of concrete materials that represent fractions with mixed numbers.

2) Solve story problems involving addition of fractions with mixed numbers using concrete materials.

3) Solve equations involving addition of fractions with mixed numbers using concrete materials.

Important Ideas for Implementation:

1) It is important to first provide students with “pure” concrete experiences where students combine sets of concrete objects that represent fractions with mixed numbers (e.g. sets that include both wholes and fractional parts.) After students demonstrate mastery for combining sets with “wholes” and fractional parts, then begin introducing the mathematical language and mathematical symbols in conjunction with the concrete materials.
