## Teachers notes: Don Bradman

### Number

#### A student:

- counts, orders, estimates and describes money or measurements with whole numbers, fractions and decimal fractions.
- recognises, continues and invents patterns involving addition, subtraction, multiplication and division of whole numbers.
- uses understandings of whole and fractional numbers, relationships and operations to make and complete simple equations, e.g. (19 + 6) x ? = 50 or (19 +?) x 2 = 50.
- decides whether to add, subtract, multiply or divide when dealing with everyday problems using money and familiar measurements.
- devises strategies for mental addition and subtraction of whole numbers up to 100, including multiplying numbers to 10.
- understands and uses written methods to add and subtract whole numbers and amounts of money.
- multiplies and divides whole numbers by single digit whole numbers.
- uses a calculator efficiently to work with whole numbers and amounts of money.

Sir Donald Bradman, a habitual breaker of records and Australia’s most famous sporting figure, is widely regarded as the greatest batsman in the history of the game. Many Australians know his statistics better than they know their own number plates.

### Activity

- Don Bradman was born 27 August 1908 and died 25 February 2001. Calculate his exact age (years + days).
- Bradman was knighted for services to cricket in 1949. Which period of his life was longer, as a knight, or before he was a knight?
- Don Bradman scored 6996 test runs in 80 innings with 10 not outs. His average was 99.94. To find this average, we subtract the number of not outs from the number of innings, then divide the number of runs by the result:
- Look at the length of a cricket pitch, estimate its approximate distance. Then measure the actual distance.

6996 (80 − 10) = 99.94.

Calculate Bradman’s first-class average from the following: He scored 28 067 first-class runs in 338 innings with 43 not outs.

- Bradman began his record-breaking innings at Leeds in the first over of the day and by lunch had reached 100. At the end of the day he was on 309. How many runs did he score after lunch?
- At the age of 40, Bradman scored 173 not out in the last innings of the Fourth Test at Leeds. Australia’s total score was 404. How many runs did the rest of the team score? If Bradman was 40 years old, in what year was this Test played?
- If Bradman made his first-class debut in 1927, and retired from cricket in 1949 how many years did he play first-class cricket? How old was he when he started? How old when he retired? How many more years did he live after retiring?
