Roll 6 dice to make 2 x 3-digit numbers.
Write the 2 numbers on the ground.
Draw an empty number line and write the largest number at the start of the number line.
Say the smallest number aloud and then partition using physical activity. Hundreds = star jumps, tens: lunges and ones: high knees. For example, for the number 985 students would need to do 9-star jumps, 8 lunges and 5 high knees.
