Introduction
Read the Headline Story to the students. Encourage them to create problems that can be solved using information from the story.
(Teacher note: You may wish to have students record in a table the total number of cookies and the number on each plate.)
Headline Story
A number of cookies may be divided onto two plates so that each plate contains the same number of cookies. How many cookies might there be and how could they be split.
Possible student responses
- If there were two-dozen cookies, there would be one dozen, or 12 cookies on each plate.
- If there is an even number of cookies there are only whole cookies on the plates, but if there is an odd number of cookies, one cookie can be broken in half and there will still be an equal number on both plates.
