Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit 1.i. Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. ii. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. 2.Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale. 3. Apply the area and perimeter formulas for rectangles in real world and mathematical problems. 5.a.ii. Understand the meaning of 1 degree. b. An angle that turns through n one-degree angles is said to have an angle measure of n degrees. 6. Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure. 7.i. Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. [should be a part of 4.MD.5a - only additive attributes can be measured by iterating units] ii. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure. #### Record not available. #### U Fix It with Ziff #### Fill it to Capacity #### Mountain Man Measurement Rendezvous #### Measurement: It Takes Ten #### A Brownie Bake #### By the Numbers #### Backyard Graphing #### How Big Is a Foot? #### Jumping Jack Math #### Try Your Hand at Nano #### Size, Scale and Models #### Star Gazing #### Airfoils #### Record not available. #### Record not available. #### Shapes and Angles #### Found Pounds #### Space Weather Action Center
