Bar and Pie Charts
by Anonymous
Show the same data as a strip chart and a pie chart, then change the number of items to see how the percentages shift.
About this app
A hands-on elementary math activity for learning how the same set of 20 favorite-fruit responses can be represented with a strip graph and a pie chart. Adjust the number of people in each fruit category and observe how proportions change as strip lengths and pie-slice areas. Four missions in each graph mode and a graph-reading challenge help learners connect counts with percentages.
