Data Detective

Read the graph: answer questions about bar charts, picture graphs and line graphs. Level the towers: move blocks until every tower is the same height to see the mean, then find medians, modes and ranges. Make a graph: count tally marks and build the bar graph.

About Data Detective

Data Detective builds the skills children need to read the graphs they meet in school and the news. Every round makes a new graph about favorite fruit, class pets, ice cream sales, rainy days or books read, then asks which is most, how many more, the total, or when a line went up the most. Picture graphs remind children to check what one picture stands for.

Level the towers makes the mean visible: children move blocks from tall towers to short ones until every tower is the same height, and that height is the average. Then they find the median, mode and range of short lists, with a clear explanation after every answer.

Make a graph turns tally marks into a bar graph that children build themselves, one bar at a time. A robot checked thousands of generated questions to make sure each has exactly one right answer.
