2x Board games
In pairs, students roll either 2 or 3 dice (depending on board) and use mental maths to add the numbers together. If their number appears in a circle they can cross it out. If it does not, they wait until it is their turn again to try their luck.
I laminate copies and have students use whiteboard markers to cross out numbers.
You can use counters for students who are not yet ready for mental math strategies.
