Sorting is a math skill that requires the kids to organize items into groups based on common characteristics like colour, shape, texture, size etc.
What is sorting?
Sorting means arranging things according to size, shape or colour
Sorting helps children to understand the nature of mathematics. It is a natural act for children and they find it very interesting..
The kids in the class can be separated into two groups based on the colour of their shirts or their skin complexion. Example, you ask all the kids in white shirt to stand one side and all the kids in red shirt to stand in another side. You have sorted the class into two groups using colour of shirt as the attribute
After the grouping, the kids should be able to explain why they grouped the items as they did.
To teach the kids sorting, you start by introducing a group of four items in which all items share common characteristics except one.
In the shapes above, all the shapes are triangle except one. Ask the kids to point out the one which does not belong with others.
When they give you the answer, ask them why they choose the answer. You want to know if they can point out shape as the attribute for sorting.
Another example, you can line up three pencils and one book and ask them to point out the item that does not belong with the others.
When the kids point out the one that does not belong, ask them to explain why the other three items go together.
You can draw three balls on the board and one cup. Ask the kids to circle the one that does not belong with the others.
I like to use prompting questions to know if the kids understand the concept.
The topic is presented step by step
The class teacher revises the previous topics
He introduces the new topic
The class teacher allows the pupils to give their own examples and he corrects them when the needs arise
FILL THE GAPS
Sort out school bags based on their colours
- classify pupils based on religion
- sort out the colours or pencils based on red, blue or green
- Why did you choose the cup and not the balls?
- We choose cup because others are all balls but only this one is
- After they must have chosen the one that does not belong) why did you circle the cup?
- We circle the cup because cup is The other three are all balls.
The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.
The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.
He or she does the necessary corrections when and where the needs arise.
