- 2.MD.A.1Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
- 2.MD.A.2Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen
- 2.MD.A.3Estimate lengths using units of inches, feet, centimeters, and meters.
- 2.MD.A.4Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

Counting Bugs

2nd Grade Math

» Unit:

Adding and Subtracting the Basics

Big Idea:Students need to experience real life math situations. They also need to become comfortable sharing their understandings with others.

Equal Amounts

2nd Grade Math

» Unit:

Adding and Subtracting the Basics

Big Idea:Students are expected to grasp that measuring the same object with different units can yield a different number, but represent the same quantity.

Adding and Subtracting with Lengths

2nd Grade Math

» Unit:

Length

Big Idea:Students will use their addition and subtraction strategies to measure and compare distances, solving using centimeter units.

Lines and Line Segments

2nd Grade Math

» Unit:

Geometry

Big Idea:Common Core expectations for second grade are that students will be able to measure a line segment, record the length in appropriate units, and add and subtract to compare the lengths of the lines.

Math Treasure Hunt

2nd Grade Math

» Unit:

Length

Big Idea:Students have worked with models and strategies to solve a variety of math problems. Today they will need to use those strategies to complete the math tasks.

Measurement and Symmetry

2nd Grade Math

» Unit:

Length

Big Idea:Students should be able to use a variety of measurement tools to measure both small and larger distances. Common Core Standards expect students to measure and compare those distances.
