Previously Published Data 1.) Students will complete a worksheet comparing how many objects of different sizes will fit in a container (as was experienced in the Teacher Strategy with the baby food jars). 2.) Students will repeat the volume investigation with different sized containers, such as pint jars or cubic containers. They will predict the similarities and differences of their results based on the similarities and differences of the containers. |
Previously Published Data 1.) Students will work individually with a teacher/ helper in their estimation assessment. Presented with a baby food jar (or any other slightly larger jar), students will estimate how many walnuts it will take to fill the jar. They record their answers on a record sheet as well as orally. Students then count the walnuts as they fill the jar. Next, they will explain why it will take more or fewer objects of other sizes to fill the container. 2.) Students will explain the different strategies they use in estimation. |
