Content Standards/Technology Standards 
Alien AnglesEstimating angles What's My Angle? 
Common Core Standard: 4.MD.6 Measure angles in wholenumber degrees using a protractor. Sketch angles of specified measure. 

Technology Standards: Standard 3.0 Technology for learning and collaboration: students will use a variety of technologies for learning and collaboration 

Lines and Angles  91, 92 
Common Core: 4.G1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in twodimensional figures. 4.MD.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement. 
Technology Standards: Standard 3.0 Technology for learning and collaboration: students will use a variety of technologies for learning and collaboration  
Quadrilaterals  95, 96 
Common Core: 4.G.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.
