Imagine that I am going to snap my fingers and make the best professional baseball hitter of all time and a professional baseball pitcher appear before your very eyes. If I was to tell the pitcher to throw 10 pitches in a games to the hitter, how many out of ten do you think he would hit?
The students predominantly said that the hitter would hit between 7 and 10 out of 10 pitches. I then introduced the 25 best batting averages of all time. They were shocked to see that the very best of the best, Ty Cobb, had a lifetime average of 0.366 or roughly 36%. This set the stage for them to keep track of and record their average out of ten. I do not have enough bats for everyone, so opted to use a tennis racket and a soft ball instead. They had to:
A) Record how many hits out of ten in fraction form and convert it to a decimal point.
B) Record how many kicks out of ten rolls of the ball from the pitcher in fraction form and convert to decimal point.
C) Do a mini-reflection on their performance.
Please see video and slide show below. It was a very successful class and suggest you try it out.
I did this lesson twice yesterday with two different grade 3 classes. The first class I did not have the decimal column on the worksheet. After collaborating with the grade 3 teachers, it was decided that I would add the decimal. Despite not putting the decimal column on the worksheet in the first class, it was still a great maths connection.
