12/1/2015
Unit Name: Lines and Angles
4.G.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures. Essential Vocabulary: lines angle point line segment ray vertex/vertices oblique plane perpendicular parallel line of symmetry polygon right angle obtuse angle acute angle Unit Overview: In this unit, students will be identifying angles and be able to explain/reason with different types of angles. This is the first time the students will be exposed to rays, angles, perpendicular and parallel lines. Strategies/Skills: Students will build on their understanding of geometric shapes and go further with a variety of properties. Students will model mastery of this concept through the following ways: building drawing identifying analyzing Video Support: o Draw points, lines, and line segments https://learnzillion.com/lessons/2346-draw-points-lines-and-line-segments o Classify and draw various types of angles https://learnzillion.com/lessons/2395-classify-and-draw-various-types-of-angles o Draw parallel and perpendicular lines https://learnzillion.com/lessons/2313-draw-parallel-and-perpendicular-lines o Label and name points, lines, rays and angles using math notation https://learnzillion.com/lessons/2416-label-and-name-points-lines-rays-and-angles-using- math-notation
