Directions:
I rolled 2 dice and when I counted the pips (dots), there were 5 altogether.
What could I have rolled on the dice?
I rolled again and got 5 again, but I didn’t get the same numbers as before. What could my new roll be?
Hint
If you rolled a 4, how many more would you need to get to 5?
If you rolled a 3, how many more would you need to get to 5?
If you rolled a 3, how many more would you need to get to 5?
Answer
There are a couple of different possible answers.
1 and 4, then 2 and 3
2 and 3, then 1 and 4.
The order of the dice in each pair can switch, eg. 4 and 1.
