MP5.
Use appropriate tools strategically.

Students use fraction circle pieces to represent fractions and to define a unit whole when given a fraction of the whole. They write fractions in words and numbers.

E1.
Represent and identify fractions (e.g., proper, improper, mixed number) using area models, drawings, number lines, words, symbols, and number sentences.
E2.
Recognize that equal fractional parts of a unit whole are the same size (e.g., all fourths of a rectangle are the same size).
E3.
Identify the unit whole when given a fractional part of a whole.
E6.
Compare and order fractions using tools (e.g., area models, number lines), benchmarks, and multiplication and division strategies to find common denominators.
MPE5.
Show my work. I show or tell how I arrived at my answer so someone else can understand my thinking.
