Reasoned Rounding is a rounding game for 2 players.
You will need arecording sheet shared between the 2 players.
One sheet is enough for three games.
The first player rolls a 0-9 die twice and chooses which two-digit number they would like to make from the numbers rolled.
They then have to round this to the nearest value of 10, find the matching circle on the recording sheet and write their two digit number in one of the spaces in that circle.
Player two rolls the die twice to take their turn in a similar way.
A circle is complete when it has two numbers in it and this scores a point for the person who wrote the second number in. (Even if the first number was written in by the other player.)
The game is over when all the circles are full and then the points are counted up to find the winner.
