4NR4: Solve real-life problems involving addition, subtraction, equivalence, and comparison of fractions with denominators of 2, 3, 4, 5, 6, 8, 10, 12 and 100 using part-whole strategies and visual models.

4NR4.1 Using concrete materials, drawings and number lines, demonstrate and explain the relationship between equivalent fractions, including fractions greater than one, and explain the identity property of multiplication as it relates to equivalent fractions. Generate equivalent fractions using these relationships.

4NR4.2: Compare two fractions with the same numerator of the same denominator by reasoning about their size and recognize that comparisons are valid only when the two fractions refer to the same whole.

4NR4.4: Represent whole numbers and fractions as the sum of unit fractions. 

4NR4.5: Represent a fraction as a sum of fractions with the same denominator in more than one way, recording with an equation.

4NR4.6: Add and subtraction fractions and mixed numbers with like denominators using a variety of tools. 

4NR5: Solve real-life problems involving addition, equivalence, comparison of fractions with denominators of 10 and 100, and comparison of decimal numbers as tenths and hundredths using part-whole strategies and visual models.

4NR5.1: Demonstrate and explain the concept of equivalent fractions with denominators of 10 and 100, using concrete materials and visual models. Add two fractions with denominators of 10 and 100.
