  • 4.G.2 Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence of absence of angles of a specified size. Recognize right triangles as a category and identify right triangles. (MP.7)
  • 4.G.3.a Recognize a line of symmetry for a two-dimensional figure.
  • 4.G.3.b Identify line-symmetric figures and draw lines of symmetry.

MEASUREMENT AND DATA

  • 4.MD.2.a Solve measurement problems involving whole number, simple fractions or decimals.
  • 4.MD.2.b Solve problems that require converting a given measurement from a larger unit to a smaller unit within a common measurement system, such as 2 km=2,000 m.
  • 4.MD.2.c Visually display measurement quantities using representations such as number lines that feature a measurement scale.
  • 4.MD.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems. (MP.1, MP.3)
  • 4.MD.4.a Identify a statistical question focused on numerical data.
  • 4.MD.4.b Make a dot plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8).
  • 4.MD.4.c Solve problems involving addition and subtraction of fractions by using information presented in dot plots.
  • 4.MD.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint and understand concepts of angle measurement. (MP.7)
  • 4.MD.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure. (MP.5, MP.6)
  • 4.MD.7 Recognize angle measure as additive. When an angle is into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems. (MP.1, MP.4)
