MD-Measure+and+estimate+lengths+in+standard+units

2.MD.1. Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. 2.MD.2. Measure 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.3. Estimate lengths using units of inches, feet, centimeters, and meters. 2.MD.4. Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit. || ===‍‍‍**Anchor Standard/Mathematical Practice(s)**=== __Mathematical Practices__ MP2. Reason abstractly and quantitatively. MP3. Construct viable arguments and critique the reasoning of others. MP5. Use appropriate tools strategically. MP6. Attend to precision. MP7. Look for and make use of structure. || 2.IN.1.2 Summarize appropriate reading strategies when reading for information. 2.TT.1.2 Use a variety of technology tools to organize data and information (e.g., word processor, graphic organizer, audio and visual recording, online collaboration tools, etc.). 2.TT.1.3 Use technology tools to present data and information (multimedia, audio and visual recording, online collaboration tools, etc.). 2.SE.1.1 Use technology hardware and software responsibly. || ===‍‍‍**Revised Bloom's Level of thinking**=== Level 1 - Remembering Exhibit memory of previously learned material by recalling facts, terms, basic concepts, and answers. Level 2 - Understanding Demonstrate understanding of facts and ideas by organizing, comparing, translating, interpreting, giving descriptions, and stating main ideas. Level 3 - Applying Solve problems to new situations by applying acquired knowledge, facts, techniques and rules in a different way.

‍‍‍**Intervention:**

 * Possible Activities: **

[|Measuring Strips]

[|Measuring Paths]

[|Path 1]

[|Path 2]

[|Path 3] (See first resource) Students can measure the length of an object using two units of measure.

Measurement with two units (See last resource for lesson)

=** Measurement Games **=


 * Side Step: **

-Stand with both feet together on the line.

-Estimate the length of your step.

-Take a giant step to the side with one foot.

-Mark the inside of your foot where it lands.

-Measure the width of your step.

-Record the results on the worksheet.

Students could work with a partner and measure their hands and feet, then compare.

Classroom Strategies:

2.01 T - Making Paper Airplanes Classroom Strategies: 2.01 EE Scavenger Hunt Students could work with a partner and measure their hands and feet, then compare.

If students already know this skill I will: =** Measurement Games **= -Two student stand at the tape line on the floor. -With one hand they will throw their cotton ball as far as they can. -Measure the distance that each cotton ball traveled. -Then they will measure to see whose cotton ball traveled the farthest. -Record the results on the worksheet. (See first resource)
 * Cotton Ball Throw: **

‍‍‍**Enrichment:**
Measure two larger objects and write about the differences in their lengths. Classroom Strategies:
