Equipment Needed : Photocopies of tenths, hundredths and thousandths squares. Sixteen doughnut puzzle pieces.
Victorian Curriculum outcome : Make connections between equivalent fractions, decimals and percentages.
Task description : Students solve the doughnut puzzle by creating four four-domino doughnuts where the meeting ends are equivalent. Once they have done this, they prove each connection using decimal and fraction squares.
Assessment options : Photograph of doughnuts with proofs.
Teacher notes : Some proofs are much harder than others: particularly those that involve thirds. Encourage students to see that percentage means โ€œout of 100โ€ and so all percentages should be done with a hundredths square.
