Collect it, show it, and figure out what it's telling you — learn to read and build graphs and answer real questions with data, with more graphs and statistics lessons to come.
Sort shapes into groups by color, shape, or size, count with tally marks in groups of five, and build tally charts from a scatter of pictures.
Start sorting →Read picture graphs and bar graphs using keys and scales, answer "how many more?" and "how many in all?" questions, then build your own by tapping pictures and dragging bars.
Start graphing →See how things change over time. Read points, spot when data goes up or down, find the biggest change, then plot your own line graphs and match graphs to stories.
Start graphing →See data as parts of a whole. Read slices as fractions and percents, find how many are in each part, then build circle graphs by dragging slice edges and match graphs to data.
Start graphing →Level out stacks of cubes to find the mean, cross off numbers to find the median, spot the mode, and measure the range — then build a data set that hits a target.
