Lesson Study Video for Multiplication Algorithm: Vertical Form (7 of 7)

Start 42:08, length 4:02

The teacher has found that some children have used the standard vertical form of laying out the problem. In the clip, he encourages one of them to explain her idea. He then links the vertical form to the other methods using pictures and places a picture by the vertical sum for direct comparison. After the episode shown, there is a 5 minute session summarizing the lesson in which Mr Muramato gets the children to read the purpose of the lesson from the board and to suggest a form of words to describe the lesson. The whole board is laid out from left to right with the main ideas of the lesson enabling the children to see the full argument and to make their own notes.
