Fourth grade students compare, order, and represent whole numbers to the billions place, compare, order, and represent decimals through the hundredths place with comparison symbols and a number line, and relate decimals to fractions.Students will also represent fractions as a sum of fractions, decompose a fraction, determine when fractions are equivalent, and represent fractions and decimals on a number line.
