A maths lesson activity with a toy car.
The video shows the results when the car is pulled back 5 cm, 15cm and 25 cm.
In Part Two of the video, the results are shown when the car is pulled back 10 cm, 20 cm and 30 cm.
My thought is that the teacher would show the first three results and make a table of the data. Then, make predictions for 10 cm, 20 cm and 30 cm.
