๐ Topic Summary
Fractions show parts of a whole. A number line can help us see fractions visually. When a number line is divided into equal parts, each part represents a fraction. The bottom number (denominator) tells us how many total parts there are, and the top number (numerator) tells us how many parts we are counting. Think of it like sharing a pizza! ๐
For example, if a number line is divided into 4 equal parts, each part is $\frac{1}{4}$. If we count three of those parts, we have $\frac{3}{4}$. Practice makes perfect, so let's jump into some exercises!
๐ก Part A: Vocabulary

(Match the terms above with the correct definitions. Answers are at the bottom.)
โ๏ธ Part B: Fill in the Blanks
Use the words numerator, denominator, equal, and fraction to complete the paragraph.
A _______ represents a part of a whole. The _______ tells us how many _______ parts there are in total, and the _______ tells us how many parts we are considering.
๐ค Part C: Critical Thinking
Imagine you have a number line showing fractions between 0 and 1. How would you explain to a friend where to find the fraction $\frac{1}{2}$ on that number line?
Answer Key: Part A: 1-C, 2-A, 3-D, 4-B, 5-E. Part B: fraction, denominator, equal, numerator.
