# In Second Grade

• Second grade students composed and decomposed numbers to 1,200 using concrete and pictorial models in more than one way, generated a number that is greater or less than a given number, and located a given number on a open number line. Students also used standard, word, and expanded forms to represent numbers to 1,200, and used comparative language, numbers, and symbols to compare and order numbers to 1,200.

# In Third Grade

• Next year in third grade, students will compose and decompose numbers up to 100,000, compare, order, and represent numbers using comparison symbols, and use a number line to represent numbers.

Students will represent fractions using strip diagrams, number lines, concrete objects, and pictorial models, represent equivalent fractions with denominators of 2, 3, 4, 6, and 8 using objects, pictorial models, and number lines, and compare two fractions having the same numerator or denominator.

# 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.
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.
