Math Roll and Write is a fun activity that engages students while they practice math fluency. Students roll dice, create numbers, add or subtract, check answers, compare the sum or difference to determine their score, and work with their peers. There are 4 usable sheets, 2 addition with decimals and 2 subtraction with decimals. All you need to do is copy them and supply the dice.
This would be appropriate for 4th and 5th grade.
I hope this helps your students with math fluency!
