Use this worksheet along with a makeshift basket (some sort of bucket/box) and a ball (tennis ball size and soft) to turn converting fractions to decimals and percentages into a fun game for the class.
Prepare a set of cards with possible denominators of the fractions you want to work with during the lesson. These will be the number of shots a pupil can have at the basket.
After selecting a pupil, they come up and choose a card from the denominator deck. This will tell them how many chances to make a basket they have. They then get the ball and take their shots. (Note: I tend to say that if they make a shot they are to take one step back – this decreases the chance of getting too many perfect plays.) Get one pupil to count the number of shots they have taken total and another pupil to count the number of baskets they have made.
Once the turn is over, pupils fill in the sheet with that pupil’s basket information. (Note: I get the pupils to write the turn taker’s initials by the information for discussions at the end.)
Gameplay continues like this as time permits.
At the end, I tend to conclude with a discussion about ease of comparison between scores looking at the fractions column and the decimals or percentages column and a few analysis questions.
- Did you spot any patterns?
- Who had the best score?
- Is it easier to get a high percentage score if you had fewer shots?
- Can you find the average (mean, mode etc.) percentage or decimal score and then compare your score to the average?
I use a random name selector to choose pupils to play the game. This tends to eliminate any reluctance to participate and the pupils really enjoy the mystery of who will be chosen next. I reccommend Brocksoft’s Teaching Aid: Who’s Next? as a good random name generator. It has the option to save pupil name lists, allows repeated or one time only selections and the visual and audio aspects are engaging.
- A worksheet for every pupil
- Basket and ball
- Board to write on for the teacher
- Set of cards with 2, 3, 4, 5, 6, 7 etc on them
