Huia Whanau have been learning how to add and subtract large numbers in maths. We have been using our knowledge of place value, and applying it to vertical algorithms. It is really important that we understand the difference between numbers and digits, and recognise that digits can represent different values, depending on their place within the number.
Here is a poster that I made using google slides and screencastify, that explains how digits can have different values within a number. What do you think?
