Roll dice to fill out number sentences and then solve according to the order of operations.   This student led activity will have them creating the number sentences to solve.   There are three versions included in the resource which can be used to help with differentiation. The first version includes addition, subtraction and multiplication. The second incorporates division as well as brackets. The third uses brackets for all questions.   If you are wanting additional ways to challenge your students, have them roll larger numbered dice.   Some combinations may result in negative and decimal numbers.
