MAFS.2.MD.1.3

Estimate lengths using units of inches, feet, yards, centimeters, and meters.
General Information
Subject Area: Mathematics
Grade: 2
Domain-Subdomain: Measurement and Data
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.

Type: Educational Game

Formative Assessments

Estimating in Yards:

Students are asked to estimate a predetermined length in yards.

Type: Formative Assessment

Lesson Plans

Estimating lengths & distances:

This lesson is designed to help students estimate lengths using standard and metric units of measure. They will participate in a teacher-guided activity, estimating then measuring how far a ball rolls on 3 different surfaces. They will also estimate then measure about 10 items that are found around the classroom. While they are estimating and measuring, they have to decide what unit of measure is best suited for the specific object.

Type: Lesson Plan

Can I make a reasonable guess? Estimating using inches, feet, centimeters, and meters.:

This lesson uses a discovery approach to estimate the length of objects using inches, feet, meters and centimeters. The students will utilize math standard(s) as they analyze math solutions and explain their solutions. Since this lesson uses estimation, it is a good lesson to use to gain knowledge of how realistic students are with units of measurements.

Type: Lesson Plan

Measuring Madness:

This lesson consists of a fun inquiry-based activity that guides children to understand how to estimate lengths using inches, feet, centimeters, and meters! It can be used towards the end of a unit on measurements due to the fact that they must have knowledge on all four units.

Type: Lesson Plan

Measurement Mania:

This lesson provides students with a hands - on opportunity to estimate and measure real - world objects. The students will be using various units of measure.

Type: 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. They will have the opportunity to problem solve since rulers will not be allowed! Students can engage in communication and cooperative learning by sharing strategies, comparing answers and defending their work. This is a good lesson to use after students have been introduced to measuring and units of measurement.

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.
