Interpret Line Graphs

Discover how to read and understand data presented in line graphs!

What Are Line Graphs?

Line graphs are like treasure maps for data!
They show how things change over time by connecting points with lines. The horizontal axis (x-axis) usually shows time, and the vertical axis (y-axis) shows what's being measured. By reading the ups and downs of the line, we can spot patterns and make predictions!

How to Read a Line Graph

1️⃣ Check the axes - What's being measured and over what time period?

2️⃣ Follow the line - Look for upward, downward, or steady trends

3️⃣ Find specific points - What was the value at a particular time?

Let's Practice Together!

Example 1: Temperature Changes

Look at this line graph showing the temperature over a week:

On which day was the temperature exactly 20°C?
Monday
Wednesday
Friday
Sunday
Great job! The line crosses 20°C right in the middle of Wednesday.
Look again! Find where the line crosses the 20°C mark on the left side.

Example 2: Puppy Growth

This graph shows how much Max the puppy weighed each month:

Between which two months did Max gain the most weight?
Month 1 to Month 2
Month 3 to Month 4
Month 5 to Month 6
Excellent! The line is steepest between months 3 and 4, showing the biggest growth spurt!
Not quite! Look for where the line goes up the most sharply between two points.

Parent Tips 🌟

  • Make it real: Create simple line graphs together tracking daily temperatures, screen time, or plant growth to show practical uses.
  • Sports stats: Use sports statistics (like a player's points per game) to make interpreting graphs exciting for sports fans.
  • Predict the future: After analyzing a graph, ask your child to predict what might happen next based on the trend.
