### Random or not: explore numbers of jubes (1:1:1)

Test a machine that randomly packages three types of fruit jubes: penguin, fish or frog. Notice that each jube type is equally likely to be produced within a packet of 12 jubes. Look at patterns in numbers of jube types, such as 3 penguins, 4 fish and 5 frogs (the most common in a sample). Manually choose jube types for ...

### Random or not: explore numbers of jubes (1:1)

### Wishball: thousandths

Test your understanding of decimal place value with numbers that include thousandths. Receive a starting number, such as 3.569, and work towards turning it into a target number, such as 7.832. Spin a random digit, choose its decimal place value and decide whether to add or subtract the random digit from your starting number. ...
