Divide your students into 5 groups with variable
numbers in them. Give each group a number of cookies
that does not divide evenly, with clear instuctions that
they can not eat any cookies yet!
Without breaking any cookies share cookies evenly. Have the students take extras and find how many pieces they must cut into to share then equally. Have the students record their results. The students are to take one cookie from the total and share the one cookie. It must be divided with a knife. Then the tsudents can eat that one cookie. Now have each group redo this activity with one less cookie. Have them repeat each time until there are no cookies left, recording results each time. Instruct your students to write a one paragraph essay, discussing their results. Steer the essays to answer what they learnt by repeating the process the way they did. |
