The first instance of Solving problems with bar graphs 3 is under the 3rd grade (U.S.) Math Mission. In this exercise users practice interpreting and reading bar charts.

Types of Problems

There are three types of problems in this exercise:

  1. Find numerical answer: This problem asks users to use a bar chart to find the numerical answer to a question. The answer is typed into an answer box.

    Find numerical answer

  2. Multiple select interpretation: This problem asks the user to use a bar chart and select all things that satisfy some given condition.

    Multiple select interpretation

  3. Select from drop-down: This problem asks the user to use a bar chart and select the option from a drop-down menu that correct answers a question.

    Select from drop-down


This exercise is easy to get accuracy badges because graphs and labels are very clear. Speed badges are medium because there are different problem types to be ready for.

  1. It is slighter easier (and hence faster) to count the spaces on vertical axis and then use the scale to multiply to certain answers.
  2. Problem type three is the fastest to answer and can be done as fast as students can read.

Real-life Applications

  1. The bar graphs in this exercise can be in real-world situations.
