**Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit**

**4.MD.A.1 **Know relative sizes of measurement units within one system
of units including km, m, cm; kg, g; lb, oz; l, ml; hr, min, sec. Within
a single system of measurement, express measurements in a larger unit
terms of a smaller unit. Record measurement equivalents in a two-column
table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36)... **Sample Activities:**

**Represent and interpret data****4.MD.B.4** Make a line plot to display a data set of measurements in fractions of a unit (1/2, ¼, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots. For example, from a line plot find and interpret the difference in length between the longest and shortest specimens in an insect collection.**Sample Activity:****Objects in My Desk Line Plot**

**Geometric measurement: understand concepts of angle and measure angles****4.MD.C.5 **Recognize angles as geometric shapes that are formed whenever two rays share a common endpoint, and understand concepts of angle measurement:

a. An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.

b. An angle that turns through n one-degree angles is said to have an angle measure of n degrees.**Sample Activity:****Angles in Circles**
