Interpret Line Graphs

Discover how to read and understand information from line graphs!

What Are Line Graphs?

Line graphs are like storybooks for numbers!
They show how things change over time by connecting dots with lines. The horizontal line (x-axis) usually shows time (like days or months), and the vertical line (y-axis) shows what we're measuring (like temperature or number of books read).

How to Read a Line Graph

1️⃣ Look at the title - What is the graph about?

2️⃣ Check the axes - What do the x-axis and y-axis represent?

3️⃣ Follow the line - How does it go up, down, or stay the same?

Let's Practice Together!

Example 1: Ice Cream Sales

$120 $90 $60 $30 Mon Tue Wed Thu Fri

On which day were the most ice creams sold? How much money was made that day?

Wednesday was the best day! The shop made $120 that day (the highest point on the graph).

Example 2: Plant Growth

20 cm 15 cm 10 cm 5 cm Week 1 Week 2 Week 3 Week 4 Week 5

How much did the plant grow between Week 1 and Week 5?

The plant grew from 5 cm to 15 cm, so it grew 10 cm in total!

Parent Tips 🌟

  • Make it real: Create simple line graphs together tracking daily temperatures, steps taken, or minutes read each day.
  • Play detective: Ask questions like "When was the highest point?" or "Did it increase or decrease overall?" to build interpretation skills.
  • Connect to interests: Help your child find line graphs about their favorite topics (sports stats, animal populations, etc.) to make learning relevant.
