Solving Word problems with bar graphs and Pictographs

Front

What is a bar graph?

Back

A bar graph is a visual representation of data using bars of different heights or lengths to compare quantities across categories.

Front

What is a pictograph?

Back

A pictograph is a chart that uses pictures or symbols to represent data, where each picture represents a certain number of items.

How do you determine the total quantity represented in a bar graph?

Back

To determine the total quantity, add the values represented by each bar in the graph.

Front

What does it mean to compare quantities in word problems?

Back

Comparing quantities involves finding the difference or ratio between two or more amounts, often to answer questions about how much more or less one quantity is than another.

Front

How can you find the difference between two quantities in a word problem?

Back

To find the difference, subtract the smaller quantity from the larger quantity.

How do you interpret data from a pictograph?

Back

To interpret data from a pictograph, count the symbols and multiply by the value each symbol represents to find the total quantity.

Front

What is the first step in solving a word problem involving bar graphs?

Back

The first step is to read the problem carefully and identify the relevant data presented in the bar graph.

Front

How do you calculate the total number of items represented in a pictograph?

Back

To calculate the total, count the number of symbols and multiply by the number each symbol represents.

Front
