Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Measure and estimate lengths in standard units. (Major Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Educational Game
  • Estimation of Length, Area, and Volume # The students will be presented with two shapes and must estimate how many times the smaller will fit in the larger. They will be surprised at some of the results but will quickly learn and make adjustments.

Lesson Plan
  • Measurement Mystery Mayhem # In this lesson, students will use their knowledge of units of measurement to estimate the length of objects in centimeters and inches. Students will use rulers to confirm their estimations. Students will engage in communication and cooperative learning by sharing strategies, comparing answers and defending their work.

Professional Development
  • What Does It Mean To Measure? # This is a professional development session from the Learning Math series from Annenberg. Learners will begin to explore the questions "What can be measured?" and "What does it mean to measure something?" Learners identify measurable properties of objects such as weight, surface area, and volume, and discuss which metric units are appropriate for measuring these properties. Learners will also learn that measurement is, by its nature, approximate. Finally, learners will consider how to make measurements using nonstandard units. This session features a number of problems for learners to solve and open-ended questions to discuss, videos that demonstrate measurement techniques, and an interactive activity that asks learners to construct shapes using different size triangles to foster understanding of area and perimeter. There are also nine homework problems in which learners are asked to generate different measurements, graph measurements, and evaluate the appropriateness of the measurements generated using a data chart. Many of the professional development activities can be used directly in the classroom.
Teaching Idea
  • Rough Rubbin' Sharks-SeaWorld Classroom Activity # In this activity, students gain an understanding of sharks' rough, textured skin through artwork. They demonstrate knowledge of a shark's ecosystem. Students will also have the opportunity to measure/estimate different sharks using objects and rulers.
