In my research, I found that while many students in Year 3-6 could read, write and order large numbers successfully, their knowledge of renaming, representing numbers,
estimating, calculating and their general sense of number was in many cases limited.
This led me to describe these students as apparent experts in place value they appeared to know more than they actually did.
Most concerning to me was that, through no fault of their own, teachers were often unaware of these issues.
For these reasons I have designed Zero Our Hero to assist teachers to teach place value in a comprehensive and sequential manner.
The App addresses all six aspects of place value mentioned above and asks a variety of quality questions to challenge students' knowledge in each aspect.
