Grade 1 Unit of Study 9: Fractions

In This Unit of Study…

Students partition circles and rectangles into two and four equal-sized parts, and they describe the parts by using the words halves and fourths. Students reason about the size of parts as they observe that when shapes are decomposed into more equal-sized parts, the shares become smaller in size. Fraction notation is not expected at this grade level.
