\({ \frac{1}{3} }\) of the sled is covered in snow.
Usually, for step 3 we would write a math sentence. Since we are creating fractions and fraction models, we do not have a math sentence to solve. We can skip step 3, and go directly to step 4, Decide how to solve!
Decide how to solve.
Great job! We need to record \({ \frac{1}{3} }\) on a number line. First, write \({ \frac{1}{3} }\) on your paper under the word problem.

\({ \frac{1}{3} }\)
Solve and label your answer.
It is time to record \({ \frac{1}{3} }\) on a number line! Follow the steps in the next few slides.
Let’s start by drawing and partitioning a rectangle. The denominator of our fraction is 3, so partition your rectangle into 3 equal parts.
Part of Caleb's sled is covered in snow! What fraction of the sled has snow on it? Record your answer on a number line.
\({ \frac{1}{3} }\). Rectangle split into 3 equal partitions.
Solve and label your answer.
Our numerator is 1, so color in 1 of the 3 parts of your partitioned rectangle.
Part of Caleb's sled is covered in snow! What fraction of the sled has snow on it? Record your answer on a number line.
\({ \frac{1}{3} }\). Rectangle split into 3 equal partitions. 1 of the parts are filled in.
Solve and label your answer.
Are you ready to draw the number line? Draw it right under the partitioned rectangle. Make sure your arrows go past both ends of the rectangle.

\({ \frac{1}{3} }\). Rectangle split into 3 equal partitions. 1 of the parts are filled in. Number line underneath.
Solve and label your answer.
Label 0 and 1 on your number line. Do not forget to draw a line segment to mark where each partition of the rectangle meets the number line.
Part of Caleb's sled is covered in snow! What fraction of the sled has snow on it? Record your answer on a number line.
\({ \frac{1}{3} }\). Rectangle split into 3 equal partitions. 1 of the parts are filled in. Number line underneath from 0 to 1 with markers for each partition.
Solve and label your answer.
Now label the fractions on your number line.
Part of Caleb's sled is covered in snow! What fraction of the sled has snow on it? Record your answer on a number line.
\({ \frac{1}{3} }\). Rectangle split into 3 equal partitions. 1 of the parts are filled in. Number line underneath from 0 to 1 with markers for each partition. Markers are labeled \({ \frac{0}{3} }\), \({ \frac{1}{3} }\), \({ \frac{2}{3} }\), \({ \frac{3}{3} }\).
Solve and label your answer.
Finish up your number line by finding \({ \frac{1}{3} }\). Draw a dot on the number line right above \({ \frac{1}{3} }\).
