### Dr. Grafoo

An essential part of the math curriculum is to have their students effectively represent key data through pictograms, block graphs and bar charts. Dr. Grafoo offers a math game that uses simulated real-life information to help students convey important facts using visually engaging graphs and charts that represent data in a clear and comprehensible way. This game is aligned with the K-3 Measurement and Data (MD) category of standards for mathematics.

While playing, students can become more familiar and practice how to turn table representations of data and tallies into a bar graph, pictogram or line plot and then analyze results. Data and other relevant information come from simple everyday items that children should be familiar with such as cereal boxes, fruits, beads and more. As a result, the student can then successfully input these items into fun graph displays.

With Dr. Grafoo, teachers can provide an individualized and creative learning session by selecting tasks for the student to complete such as:

• Create a bar chart in a vertical or horizontal direction using information in a table
• Create a picture graph from information in a table
• Understand and reuse data that is set in the form of a table with numerals or tally marks in up to five categories
• Draw a graph and add key details such as the title and headers of the “x” and “y” axes.

Teachers can also choose specific features based on the student’s needs for motor skills development. These include making the interaction mode a grab and move format or a time delay. Other modifying features include the duration of each graphing activity and the amount of questions to ask. Additionally, educators can enrich the learning experience by asking specific questions from the chart to relate the data in the headings to real life experiences students can have. This action encourages a discussion to identify possible uses of the statistics represented. This movement-based learning activity game provides fundamental benefits to the student by reinforcing mathematical learning regarding graphing data while also improving fine motor skills, critical thinking and cognitive skills.
