Students solve problems involving measurement and the conversion of measurements from a larger unit to a smaller unit. 2. Reason abstractly and quantitatively. Students reason abstractly and quantitatively by comparing, contrasting, and classifying two-dimensional shapes and determining their lines of symmetry. Students recognize angle measure as additive in relation to the reference to a circle. 3. Construct viable arguments and critique the reasoning of others. Students construct viable arguments and critique reasoning when determining the properties of geometric shapes and determining their lines of symmetry. Students construct and critique arguments regarding the relative size of measurement units and relating them to everyday objects. 2015-2016 Page 1 of 9 MADISON COUNTY PUBLIC SCHOOLS District Curriculum Map for Mathematics: Grade 4 4. Model with mathematics. Students model with mathematics by drawing, folding, tracing, and constructing lines of symmetry and categorizing twodimensional shapes based on their properties. Students use line plots to display data of measurements in fractions of a unit. 5. Use appropriate tools strategically. Students use appropriate tools such as geometric shapes, corners of paper, tiles, rulers, protractors, and/or graphic organizers to determine angles, classify two-dimensional shapes, and draw lines of symmetry. Students select and use tools such as a ruler, balance, graduated cylinder, angle ruler, and protractor to measure. 6. Attend to precision. Students attend to precision when observing and determining the attributes of sides and degree of angles within geometric shapes. Students carefully specify unit measure and state the meaning of the symbols they choose. 7. Look for and make use of structure. Students look for and make sense of structure when exploring properties of geometric shapes and determining how to fold them to show lines of symmetry. Students use the structure of a two-column table to generate a conversion table for measurement equivalence. 8. Look for and express regularity in repeated reasoning. Students look for and express regularity in repeated reasoning while exploring the geometric properties of two-dimensional shapes by comparing, contrasting, classifying, and identifying lines of symmetry. Students notice repetitive actions in computations to make generalizations about conversion of measurements from a larger unit to a smaller unit. Standards for Mathematical Content 4.G.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures. 4.G.2 Classify two-dimensional 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.3 Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry. 4.MD.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor. 4.MD.5 Recognize angles as geometric shapes that are formed wherever 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 Curriculum and Instruction 2015-2016 Page 2 of 9 MADISON COUNTY PUBLIC SCHOOLS District Curriculum Map for Mathematics: Grade 4 Supporting Standard(s) Which related standards will be incorporated to support and enhance the enduring standards? Instructional Outcomes What must students learn and be able to do by the end of the unit to demonstrate mastery? Curriculum and Instruction the circular arc between the points where the two rays intersect the circle. An angle that turns through 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. 4.MD.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure. 4.MD.7 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. 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. 4.OA.3 Solve multistep word problems posed with whole numbers and having whole-number 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. 4.MD.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.
