Interactive Spinners printable sheet
We have two spinners each numbered $1$ to $4$.
We're going to spin them both and add the numbers.
What possible totals might you get?
What is the least likely/most likely total to occur?
Can you summarise your ideas clearly? Can you justify them?
Use the interactivity to test these hypotheses.
Now make a new set of spinners, and write down a hypothesis about the possible outcomes and the shape of the relative frequency bar chart. Justify your ideas to a friend, before testing them with the interactivity.
Once you have experimented with the interactivity you might like to try this problem: Which Spinners?
