Unit Description

This unit focuses on the student's gaining an understanding that fractions are parts of a whole. It moves to understanding fractional values on a number line. The unit quickly touches on fractional sums and differences and equivalent fractions. The students learn about the relationship between fractions, percents, and decimals and learn the rules for converting between the values using a calculator. Standards covered: 4.NSO-F.9. Demonstrate an understanding of fractions as parts of unit wholes, as parts of a collection, and as locations on a number line. 4.NSO-F.10. Know the relationships among halves, fourths, and eighths and among thirds, sixths, and twelfths; compare and order such fractions. 4.NSO-F.11. Recognize, name, and generate equivalent forms of common decimals (0.5, 0.25, 0.2, 0.1) and fractions (halves, quarters, fifths, and tenths) and explain why they are equivalent.
