Mathematics Grade 2
Strand: MEASUREMENT AND DATA (2.MD)
Measure and estimate lengths in standard units (Standards 2.MD.1-4)
and relate addition and subtraction to length (Standards 2.MD.5-6)
. They work with time and money (Standards 2.MD.7-8)
. They represent and interpret data (Standards 2.MD.9-10)
Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit. For example, after measuring a pencil and a crayon, a student uses the measurements to determine that the pencil is two inches longer than the crayon.
Within the task students have the opportunity to measure and compare lengths of their own foot and that of a partner.
Grade 2 Math Module 2: Addition and Subtraction of Length Units (Engage NY)
In this 12-day Grade 2 module, students engage in activities designed to deepen their conceptual understanding of measurement and to relate addition and subtraction to length. Their work in Module 2 is exclusively with metric units in order to support place value concepts. Customary units will be introduced in Module 7.
Grade 2 Math Module 7: Problem Solving with Length, Money, and Data (Engage NY)
Module 7 presents an opportunity for students to practice addition and subtraction strategies within 100 and problem-solving skills as they learn to work with various types of units within the contexts of length, money, and data. Students represent categorical and measurement data using picture graphs, bar graphs, and line plots. They revisit measuring and estimating length from Module 2, though now using both metric and customary units.
Grade 2 Unit 3: Understanding Measurement, Length, and Time (Georgia Standards)
In this unit students will know the following customary units for measuring length: inch, foot, yard, recognize the need for standard units of measure, understand the relationship of hours and days and nderstand the importance, usefulness of reasonable estimations and e able to represent the length of several objects by making a line plot.
How Big is a Foot?
The purpose of this task is to understand the idea of a standard unit of measure and why we use them. It also reinforces the idea that we measure lengths by placing units end-to-end.
