Required Resource Materials
Kelly likes looking for insects in the garden. These are all the insects that she saw one afternoon. Can you help her display them so that she can tell her friends what she saw in the garden?
- Talk about the types of insects that you might see if you looked in the garden. As the students name the insects in this problem display them on the board.
- Read the problem for the students to work on.
- Brainstorm for ideas about how to solve the problem.
- As they work they may choose to cut out the objects to form groups or they may redraw them.
How are you sorting the insects?
How many different insects are there?
What can you tell me about the insects in the garden?
- Share displays.
Extension to the problem
Make a picture graph of the insects.
There are many ways of displaying the insects to answer the question. To develop the skills required for graphing you may decide to encourage the students to cut out the insects and put them into rows or columns for comparison.
