Math Roll and Write is a fun activity that engages students while they practice place value. Students roll dice, create numbers, write them in different forms, check answers, and work with their peers. There are 2 usable sheets, 1 with whole numbers up to hundred billion and the other 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!
