FLS: MAFS.4.MD.3.5: 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 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 angle,” and can be used to measure angles. “one-degree b. An angle that turns through n one-degree angles is said to have an angle measure of n degrees. MAFS.4.MD.3.6: Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure. Access Narrative MAFS.4.MD.3.AP.5a Identify an angle in a two-dimensional figure. MAFS.4.MD.3.AP.6a Sketch angles of specific measures. MAFS.4.MD.3.AP.6b Identify types of angles. Essential Understandings: Access Concrete Representation Understandings MAFS.4.MD.3.AP.5a Use two-dimensional Use a visual representation of a (2-D) manipulatives, (2-D) shape to identify such as pattern blocks angles. and attribute shapes, to Understand the following concepts, identify angles. symbols, and vocabulary: and degree. MAFS.4.MD.3.AP.6a Use manipulatives or Understand the following concepts, concrete objects to symbols, and vocabulary of angles: construct angles degree, acute angle, obtuse obtuse, or acute). angle, and right angle. Create angles of a given measure (right, obtuse, or acute). MAFS.4.MD.3.AP.6b Use manipulatives or Understand the following concepts, concrete objects to sort symbols, and vocabulary of angles: angles. degree, angle, acute angle, obtuse angle, and right angle. Use visual representations to identify types of angles (right, obtuse, or acute).
