Big Ideas: Linear units are used when we want to know how long an object is and squared units are used when we want to know the area an object covers. We use cubic units when we want to know how much space an object takes up or how much space is inside of an object. This lesson builds on students’ work with linear and squared measurements from previous grades. Students will identify real-life situations that call for volume measurement. This task asks students to draw a plan for a play area and determine whether linear, squared, or cubic units would be appropriate for measuring each object. This lesson prepares students for conceptual understanding when calculating volume for real-life situations in later lessons. Vocabulary: squared units, linear units, cubic units, dimensions, isometric paper
