Maths - Imaging

Teaching kids to image numbers in their head was really hard. One of many strategies that I have tried was hiding their hands and use their fingers to trace the numbers that they are using. It worked and it made my students realise that they can see numbers in their head.

1st part of the video is about this problem. "Reece picked up nine pieces of rubbish and on his way to the rubbish bin he dropped two. How many rubbish was he left with?"  ... 2nd part is about this problem - "Kaylarni had six marbles and Mikayla gave her three more marbles. How many marbles that Kaylarni had altogether?"
