Personal Objective:
This week I picked Measurement and Data at the 2nd grade level. My goal in looking at this standard was to contemplate teaching strategies that will make basic elements of measuring and estimation fun and interesting while encouraging students to explore and hone these useful skills.

Common Core Standard:
2nd Grade: 2.MD
Measure
and estimate lengths in standard units.
1. Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.
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.
3. Estimate lengths using units of inches, feet, centimeters, and meters.
4. Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit.

Reflection:
In focusing on the first four points of the Measurement and Data Common Core Standard, I immediately started to brainstorm strategies that I might use to teach the basic elements of measurement and estimation to 2nd graders. I gathered tools to measure in inches and centimeters and soon began rooting around my house for fun items to ascertain the size of. As usual, the kids toy box was my first stop. The two LEGO DUPLO people with varied height provided me with a way of representing how one could compare and identify the difference in size between two objects. In addition, I provided a simple tactic for estimation using the distance between my thumb to my pinky finger when my hand was stretched out in order to approximately represent 8 inches or 20.32cm. I'm confident there are many more fun ways that teachers can ensure students learn these elements while encouraging exploration and utilizing real life application.
Encourage students to come up with a simple trick that will provide a visual reference point when attempting to estimate the size of something. For instance, I know when my fingers are stretched out that the distance between my thumb to my pinky finger is approximately 8 inches or 20.32cm. Have students use a worksheet like the one below to select everyday items of their choice to estimate size and take a final measurement afterwards.
Measure two objects and attempt to determine how much longer one is than the other.
Resources/Tips:
-Line up what you would like to measure with the rulers, yardsticks, meter sticks, and measuring tapes
-Always start at zero
