DCM201 Division of Small Numbers
Keng Sing's lesson using When The Door Bell Rang was enjoyable with cookies and plates for the children to act division out as sharing. It could be improved by applying the theory of variation. In all the examples the children were asked to act the situation out. In the later stages, the children could be asked to draw and use the cookies to confirm their ideas.
Rebecca's use of the cut-outs was suitable. I have suggested that the writing of the division sentence happens sooner in the lesson. And that was what Wei Wen did. In her lesson on division with remainder, she made careful links between the concrete with the pictorial and abstract represents well. One suggestion is to introduce the idea of quotient a little later.
