Make 3000
You will need:
A die, some paper.
Instructions:
Together, roll a die 8 times– write down the 8 digits.
Arrange the digits to make two 4-digit numbers.
Add or subtract the two 4-digit numbers.
How close can you get to 3000?
Who was the closest?
Can you play it again with another target number?
For example:
Anna and her dad took it turns to roll the die, a total of eight times. They rolled a 4, 2, 6, 1, 1, 5, 3, and another 2.

I know 4000—1000 = 3000, so I’m going to start by putting the 4 and the 1 into the thousands columns...
I know 2000 + 1000 is 3000, but if I use a 2 and a 1 in the thousands columns, my answer will definitely be more than 3000… I’m going to put both 1 digits in the thousands columns...
