Using a tally chart to investigate

On your next bus/car/train/tram/walking journey, do some tallying! Choose four car colours and tally the different cars that you see. Remember, every time you see a car that is one of your colours, give it a tally mark. Remember, each fifth tally should make a gate. When you get home fill in the total and then get an adult or older brother or sister to ask you the questions.
