Sample
In a game of marbles, Peta and Greta were arguing about who got their marble closer to a line scratched in the sand. The diagram below shows the marbles and the line.
Peta’s marble and greta’s marble are labelled.
1. Just by look at the diagram, tick who’s marble you think is closer to the line.
There are two boxes labelled Peta's marble and Greta's marble. The student has ticked Peta’s marble.
2. To help Peta and Greta settle their argument once and for all, measure the distances yourself. (Draw lines to show where you made the measurements and label those lines with your measurements.)
The student has drawn 2 lines one from Peta's marble and one from Greta's marble. The lines have been measured and labelled - Peta's 6cm and Greta's 8cm3. Tick whose marble was closer to the line, Peta’s or Greta’s marble.
There are two boxes labelled Peta's marble and Greta's marble. The student has ticked Peta’s marble.
Billy and Natasha decide to play marbles in a circle instead. They scratched two wobbly circle shapes in the sand as shown below and decided to play in the one with the bigger area.
Peta’s shape and Greta’s shape are shown.
4. Tick who’s shape you think covers the bigger area.
Two boxes are shown. One are marked Peta and one marked Greta. The student has ticked Greta
Measure the area of each shape using the grid provided for you.
5. Tick which shape has the bigger area. Explain you answer.
Two boxes are shown. One are marked Greta and one marked Peta.
The student has ticked Greta
Greta is bigger because hers holds 27 squares and Petas has 20 1/2 squares.
