Measure angles in whole-number degrees using a protractor sketch angles of specified measure.Recognize angles as geometric shapes formed when two rays share a common endpoint, and understand angle measurement.
Make a line plot to display a data set of measurements in fractions of a unit solve problems involving addition and subtraction of fractions by using information presented in line plots.Apply the area and perimeter formulas for rectangles in real world and mathematical problems.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.Express measurements in a larger unit in terms of a smaller unit. Know relative sizes of measurement units within one system of units including km, m, cm kg, g lb, oz l, ml hr, min, sec.
