Georgia 4.NR.4.4
The Standard
Represent whole numbers and fractions as the sum of unit fractions.
Georgia's K-12 Mathematics Standards · 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.

What This Standard Means
What Students Need to Do
- Students break a fraction into repeated pieces that each have a numerator of 1. They use fraction strips, drawings, or equations to show amounts below, equal to, and above one whole.
What Mastery Looks Like
- A student can show 5/6 as five 1/6 pieces using a model and an equation. The student can also show that 2 equals eight 1/4 pieces and explain why.
Common Misconceptions
- Students may confuse the numerator with the size of each piece, writing 3/4 as three 1/3 pieces. They may also stop counting unit fractions at one whole or think a whole cannot be written with fractional pieces.
How to Assess It
- Ask students to draw a model and write 7/4 and 2 as repeated sums of 1/4.
Lesson moves
Ways to Teach It
Give students fraction strips to build 5/6 and 2 using only 1/6 pieces, then record matching equations.
Ask students to explain why six copies of 1/6 make one whole and twelve copies make two wholes.
Play a card-matching game with fraction models, number cards, and repeated unit-fraction sums.
Partition two paper pizzas into eighths, then label amounts such as 11/8 as repeated sums of 1/8.
