Creating and Interpreting Bar Graphs

The video tutorial covers a second-grade lesson on creating bar graphs. It includes activities where students use given data to make vertical and horizontal bar graphs, design surveys, and collect data. The homework focuses on practicing bar graph creation and answering related questions. The video emphasizes understanding the relationship between numbers and lines in graphs and explores different methods to solve problems using addition or subtraction.

What is the main focus of the lesson in Module 7, Lesson 5?

• Solving algebraic equations

• Understanding fractions

• Creating and interpreting bar graphs

• Learning multiplication tables

In the first activity, what type of bar graph are students asked to create?

• Pie chart

• Vertical bar graph

• Line graph

• Horizontal bar graph

What is the data about in the second activity?

• Quarters

• Nickels

• Pennies

• Dimes

What is the unique aspect of the third activity?

• 9

• 12

• 13

• 7

What is important to remember about the numbers on a bar graph?

• They go with the spaces

• They go with the lines

• They are optional

• They should be in red

What is the key to answering questions about the bar graph?
