Big Ideas: We measure using repeated units of the same size. Estimation can be more efficient than accurate measurement in some situations. Liquid volume is the amount of liquid a container can hold. This lesson builds on what students know about measurement in standard and nonstandard units. In the task, students explore estimating in a situation involving liquid volume. In the process, they will also compare metric units. This lesson builds toward 4th grade objectives which include using the four operations to solve word problems liquid volumes, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Vocabulary: estimate, measure, liquid volume, capacity, liters (L), milliliters (mL) Special Materials: graduated cylinders (optional) measuring cups (optional)
