Previously Published Data

1.) Given various objects to sort, such as nuts and bolts, buttons, shells, tiles, macaroni, students will take a box of objects, think of a way to sort them, and then do it. The teacher/ helper roams the room asking guiding questions and listening to students' responses. When students finish sorting in one way, they think of another way. As they work students will answer the following questions: "How did you decide to sort your objects this time? What is your sorting rule? Can you name each group? What will your different piles be like?" Students record one of their sorted groups by drawing it. 

2.) Students will listen to the story "A Lost Button" in Frog and Toad are Friends and complete the Buttons! Buttons! activity sheet. (This sheet is in the book Ideas - NCTM Standards-Based Instruction, University of Central Florida, Orlando, Florida. 1995, ISBN#0-87353-422-0.) Students will have access to a tape of the story to hear again. They will cross off buttons that Toad says are not his after carefully listening to the clues. After the final clue is read, one button that is not crossed off should remain on the activity sheet. Students dictate the description of the remaining button in the space provided.



Previously Published Data

1.) Students will work alone and sort a group of objects (buttons, shells, items of clothing, etc.). They will explain the rule that they used.

2.) Shown a picture of items that are grouped by like attributes, students will tell the teacher/ helper how they think each group was sorted. 

3.) Going back to the recording of the group exercise in sorting shoes, presented with a shoe of the teacher's choice, students will put it in one of the circled groups and explain their reasoning.
