# Curriculum Connections

OP H Use models to decompose fractions using unit fractions as a form of division
1
• divide whole objects into parts and identify and describe, through invesitgation, equal-sized parts of the whole, using fractional names (e.g., halves; fourths or quarters).
3
• divide whole objects and sets of objects into equal parts, and identify the parts using fractional names (e.g., one half; three thirds; two fourths or two quarters), without using numbers in standard fractional notation.
6
• represent, compare, and order fractional amounts with unlike denominators, including proper and improper fractions and mixed numbers, using a variety of tools and using standard fractional notation;
6
• determine and explain, through investigation using concrete materials, drawings, and calculators, the relationships among fractions, decimal numbers, and percents.
7
