• Third grade students composed and decomposed numbers up to 100,000, compared, ordered, and represented numbers using comparison symbols, and used a number line to represent numbers.

# In Fourth Grade

• 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.
