First, the teacher prepares a chart (see attachment )on a transparency or poster board.
Then, she draws an apple that covers most of the paper.
After that, the teacher writes on the top of the chart the following : How many seeds are there in an apple?
Next, the teacher reviews the numbers from one to thirty (1-30), by writing them on the chalkboard and having students read with her.
Then, the teacher asks the students to tell her how many seeds there are in an apple.
Next, the teacher will write the students’ estimations on the chart (or on sticky notes, so that she can reuse the chart), in order from smallest to biggest. (See attachment )
After this, the teacher will cut the apple to proceed to count the number of seeds.
Finally, write down the total number of seeds the apple has and ask the students who was closest to the number and who was furthest from the correct number of seeds:
"How many seeds does the apple have? Who was closest to the correct number? Who was furthest from the correct number?"
When you say "closest," place your hands together; when you say "furthest," place your hands apart.
