When looking at the video clip, I got a better understanding of doing subtraction. The teacher made the children to think in his class rather than doing different activities with the children. He showed different method to do a particular equation.
The place value chart was something interesting to see as it showed the hundreds, tens and ones value. With the place value chart the children will understand the concepts visually. The Geo Board was another interesting activity. The child is asked to copy the shape which the teacher has done in the Geo Board. This activity help children to visualize, copy the shape and also the concept spatial awareness.
