If there was left over string their estimation was too much. If there was not enough string their estimation was too little. If the string fit perfectly their estimation was just right. Students then graph their estimation on a class graph using their string. Next have students estimate the weight of their apple and record their estimation on their recording sheet.
Students weight their apple on the scale and record the actual weight on their recording sheet.
A class bar graph can then be created showing the students results. Lastly, have students estimate the number of seeds in their apple and record on their recording sheet. The teacher then cores each apple and the students count the number of seeds actually in their apple. In the students math journal have them write about their estimations and how it will help them make more accurate estimations in the future. For example, did they overestimate and why they think they did or did they underestimate and why they think did.
