Deepa had to introduce the concept of ‘half’ to her class of 7-yar olds. She began by asking children if they could show half of anything. Most children came up with examples by breaking a chalk piece or tearing a sheet of paper into two. Deepa allowed children to talk to each other and share their examples with the whole class. More examples emerged, such as half of a glass of water. Deepa did not emphasize that the size of the two pieces must be equal for each to be one-half of the whole. Through the entire class she did not introduce the symbol ½.
i) Do you think Deepa should have started by giving examples of ‘half’ herself? Justify your answer.
ii) Was Deepa justified in not introducing the symbol? Explain why?
iii) Suggest an activity to carry this forward on the following day.
