Concept 4 of 6
Reading Bar Graphs
Today's big idea
Read the top of each bar across to the scale on the side.
The red bar reaches 9, so red is 9.
How it works
👀 What's going on?
A bar graph turns numbers into heights. Taller bar, bigger number.
💡 Here's the trick
Read the top of each bar across to the scale on the side to find its number.
The blue bar reaches 6 and the red bar reaches 9, so blue is 6 and red is 9.
✍️ Try it
A bar reaches the line marked 8. What number is it? → 8.
⚠️ Watch out
Read where the TOP of the bar lines up, not the bottom.
