Instructions for Use


Tally Chart Lets students collect firsthand data by doing an experiment, and record it on tally charts.


To use Probability, start by selecting the dice. Choose the number of spins - 1, 5, or 10. Click the “Spin” button. A tally chart records the results of each spin. Press the “Clear Tally” button to clear the results and start again. Select the “Make Dice” button and click in the radio buttons to choose the numbers of each face of the dice. Select the “New Dice” button to choose different set amounts on the face of the dice. Students may want to experiment with the spinners. To use the spinners, select one and choose the number of spins. Click the “Spin” button. A tally chart records the results of each spin. Press the “Clear Tally” button to clear the results and start again.


Bar Graph Sorter
Students practice sorting shapes by shape or colour to create a bar graph and a tally chart.

To use the bar graph sorter, scroll down the list of activities and click on “Bar Graph Sorter” under the Statistics heading, about ¾ of the way down. Click on “Make Own or Random Shape” to make your own set or to generate a random set. Then click on “Shape” or “Colour” under the Sort by heading and click on “Horizontal” or “Vertical” to select the type of graph you wish to use. Click on a shape and drag it to either the corresponding shape or colour on the graph. The chart to the right of the graph generates a Tally Chart as each shape is places in the graph.
