Build It

Represent the fractions \(\frac{1}{3}\), \(\frac{2}{3}\), and \(\frac{3}{3}\) on a number line.
McGraw Hill My Math Grade 3 Chapter 10 Lesson 5 Answer Key Fractions on a Number Line 1
Start at the left. Place a \(\frac{1}{3}\)-fraction tile above the number line. Trace the tile. Shade in the figure.
What fraction does the shaded area represent? McGraw Hill My Math Grade 3 Chapter 10 Lesson 5 Answer Key Fractions on a Number Line 2
McGraw Hill My Math Grade 3 Chapter 10 Lesson 5 Answer Key Fractions on a Number Line 3
2. Place a second and third \(\frac{1}{3}\)-tile above the number line next to the shaded figure. Trace the tiles. Shade in the figures.
What fraction do the first two shaded areas represent together? McGraw Hill My Math Grade 3 Chapter 10 Lesson 5 Answer Key Fractions on a Number Line 2
What fraction do all three shaded areas represent? McGraw Hill My Math Grade 3 Chapter 10 Lesson 5 Answer Key Fractions on a Number Line 2
How many parts does each fraction represent?
\(\frac{1}{3}\) = ____________ part
\(\frac{2}{3}\) = _____________ parts
\(\frac{3}{3}\) = _____________ parts
Answer:
The fraction does the shaded area represent 1/3.
The fraction of the two shaded areas represent 2/3.
The fraction of all three shaded areas represent 3/3.
\(\frac{1}{3}\) = 1 part
\(\frac{2}{3}\) = 2 parts
\(\frac{3}{3}\) = 3 parts
