Essential Questions:
Unit 5 instructional time is focused on this power standard:
4.G.A.2 Classify twodimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
4.G.A.3 Recognize a line of symmetry for a twodimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify linesymmetric figures and draw lines of symmetry.
4.MD.C.7 Geometric measurement: understand concepts of angle and measure angles. Recognize angle measure as additive. When an angle is decomposed into nonoverlapping 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, e.g., by using an equation with a symbol for the unknown angle measure.
Unit 5 instruction is supported by these standards:
4.G.A.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in twodimensional figures.
4.MD.5.B An angle that turns through n onedegree angles is said to have an angle measure of n degrees.
4.MD.C.6 Measure angles in whole number degrees. Sketch angles of specific measure.
4.OA.A.3 Use the four operations with whole numbers to solve problems. Solve multistep word problems posed with whole numbers and having wholenumber answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
 How is geometry used in everyday life?
 How are geometric attributes (properties) used to solve problems in everyday life?
 How does geometry depend on measurement in order to describe shapes?
 Geometric objects can be described, classified, compared, and analyzed by their attributes.
 Geometric measurement is used in the real world.
