Show the children a visual aid containing a large grid of 4-by-10-inch rectangles.
Show them cards on which you have stamped various pictures of fruit. Put reusable adhesive on the backs of the cards. Offer the children a choice among four fruits, such as apple, orange, pear and banana. Ask the children to think about their favorites.
Ask a child to put a picture of his favorite fruit on the grid. Ask another child to do the same, either above the previous fruit, if it's the same one, or in a different column if it's a different one.
Continue asking children to express their preferences by sticking cards onto the grid. Do not ask about or point out the information the pictogram is giving, such as which fruit is currently most popular, at different stages of the process.
Total the number of times each fruit appears, with the children, after all of them have had a turn. Write the numbers at the heads of the columns. Ask the children pertinent questions, such as which fruit is most popular and which is least popular. Discuss anomalies, such as any columns with no cards in them, indicating that nobody preferred that fruit.
