Mathematics
Victoria multiplied and divided 5-digit numbers by 10, 100 and 1000 using a place-value cart and place-value dice. She arranged the dice to represent each digit and physically shifted them left or right to model the effect of moving the decimal place. By doing so she recognised how each shift added a zero at the end or removed a zero from the front, reinforcing the concept of place value magnitude. The activity also required her to check her answers, which developed her mental arithmetic and accuracy.
Tips
To deepen Victoria’s understanding, have her create her own “place-value story problems” where real-world situations require multiplying or dividing by powers of ten. Next, introduce a digital place-value game that tracks speed and accuracy, encouraging fluency. Then, explore the relationship between multiplication and division by having her reverse the operations on the same numbers and explain the process in writing. Finally, connect the concept to measurement by converting lengths between metres, centimetres and kilometres using the same place-value shifts.
