MARCH Standard Teacher’s Notes Success CriteriaMD.1.1, MD.1.2, MD.1.3, MD.1.4 (U.S. Customary), MD.2.5MAFS.2.MD.1.1: DOK 1Measure the length of an object to the nearest inch, foot, centimeter, or meter by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tape
MAFS.2.MD.1.2: DOK 2Describe the inverse relationship between the size of a unit and number of units needed to measure a given object. Ex. Suppose the perimeter of a room is lined with one-foot rulers. Now, suppose we want to line it with yardsticks instead of rulers. Will we need more or fewer yardsticks than rulers to do the job? Explain your answer.
MAFS.2.MD.1.3: DOK 1Estimate lengths using units of inches, feet, centimeters, and meters.
MAFS.2.MD.1.4: DOK 1Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard-length unit.
MAFS.2.MD.2.5 DOK 2Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.
Provide rich tasks that ask students to perform real measurements, these foundational understandings of measurement are developed.
Using both customary (inches and feet) and metric (centimeters and meters) units, Second Graders select an attribute to be measured (e.g., length of classroom), choose an appropriate unit of measurement (e.g., yardstick), and determine the number of units (e.g., yards).
Understand that larger units (e.g., yard) can be subdivided into equivalent units (e.g., inches) (partition).
Understand that the same object or many objects of the same size such as paper clips can be repeatedly used to determine the length of an object (iteration).
Understand the relationship between the size of a unit and the number of units needed (compensatory principal). Thus, the smaller the unit, the more units it will take to measure the selected attribute.
U.S. Customary for these two months-Inches, feet, yards
Use rulers divided into fourths
Iterate Color tiles, then measure
Pattern blocks-all are exactly an inch
I can tell the best type of measuring tool to use to measure different sized-objects.
I can explain why I chose the unit of measurement I used to measure an object.
When given an object, I can determine what attribute needs to be measured (length, width, height).
I can estimate the length of an object in inches, feet, or yards. I can use a ruler to measure lengths starting at the zero mark. I can explain how the size of the unit I use to measure affects the
amount of units measured. I can determine and write how much longer one object is than
another in the amount of inches, feet, or yards. I can identify and explain what the measurement problem is asking
me to find. I can solve the measurement problem using pictures, numbers, or

APRIL Standard Teacher’s Notes Success CriteriaMD.1.1, MD.1.2, MD.1.3, MD.1.4 (Metric), MD.2.5MAFS.2.MD.1.1: DOK 1Measure the length of an object to the nearest inch, foot, centimeter, or meter by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tape
MAFS.2.MD.1.2: DOK 2Describe the inverse relationship between the size of a unit and number of units needed to measure a given object. Ex. Suppose the perimeter of a room is lined with one-foot rulers. Now, suppose we want to line it with yardsticks instead of rulers. Will we need more or fewer yardsticks than rulers to do the job? Explain your answer.MAFS.2.MD.1.3: DOK 1Estimate lengths using units of inches, feet, centimeters, and meters.MAFS.2.MD.1.4: DOK 1Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard-length unit. MAFS.2.MD.2.5 DOK 2Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.
Estimate lengths in Metric for these two months-centimeters and meters
Cuisenaire Rods-increments of 1 cm from the white rod equaling 1 cm to the orange rod equaling 10 cm
Activity example: Roll the dice five times and get the corresponding rod each time. Make a train. What is the value?
Meter sticks
I can tell the best metric tool to use to measure different sized-objects. I can explain why I chose the unit of measurement I used to measure an
object. When given an object, I can determine what attribute needs to be
measured (length, width, height). I can estimate the length of an object in centimeters or meters. I can use a metric ruler to measure lengths starting at the zero mark. I can explain how the size of the unit I use to measure affects the amount
of units measured. I can determine and write how much longer one object is than another in
the amount of centimeters or meters. I can identify and explain what the measurement problem is asking me to
find. I can solve the measurement problem using pictures, numbers, or words. I can create any type of addition, subtraction, and comparison
measurement problem and explain how to solve it. I can write equations to represent my thinking, including a symbol for the
unknown.
MAY Standard Teacher’s Notes Success CriteriaMAFS.2.MD.4.9: Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units.
MAFS.2.MD.2.5 DOK 2Use addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using drawings (such as drawings of rulers) and equations with a symbol for the unknown number to represent the problem.
¼ inch ruler and centimeter rulersCuisenaire Rods- Activity Example: Grab two handfuls. Measure your rods with your metric ruler. Plot your results in a line plot.
Place a bunch of objects on each table. Each table measures the objects and creates a line plot.
Discuss similarities and differences between a line plot and a bar graph.
I can explain how a line plot is used to display data.
I can read and interpret line plots.
I can create a line plot to organize the data.
I can interpret the results of the measurement data that is plotted on the line plot.

different sized-objects. I can explain why I chose the unit of measurement I used to
measure an object. When given an object, I can determine what attribute needs
to be measured (length, width, height). I can estimate the length of an object in inches, feet, or
yards.
Provide rich tasks that ask students to perform real measurements, these foundational understandings of measurement are developed.
Using both customary (inches and feet) and metric (centimeters and meters) units, Second Graders select an attribute to be measured (e.g., length of classroom), choose an appropriate unit of measurement (e.g., yardstick), and determine the number of units (e.g., yards).
Understand that larger units (e.g., yard) can be subdivided into equivalent units (e.g., inches) (partition).

Understand that the same object or many objects of the same size such as paper clips can be repeatedly used to determine the length of an object (iteration).
Understand the relationship between the size of a unit and the number of units needed (compensatory principal). Thus, the smaller the unit, the more units it will take to measure the selected attribute.
