Collecting Data is a fun activity to do during circle time. Print, cut out, and laminate the cards. Have the children write their name on a soda cup. Tape a question card onto the wall and under it tape the yes and no cards. Read the question to the children. Have the children answer the question by placing their soda cup under the yes or no card. Count the soda cups under each column and talk about the children's answers. Ask questions like: How many of our friends like cupcakes? How many of our friends like donuts? Leave the question up and place a new question next to it. Do the same as above. Now compare each question and answers. For example: Do more children like donuts or cupcakes?
