Product Description
This guide was designed to help teachers use a digital manipulative to explore angles. The guide shares a weblink to a free digital manipulative, instructions for using the manipulative, suggested uses, example questions for whole class instruction, and example questions for small groups or individual students. Students are taught to create angles, measure angles, and estimate the measurement of angles. They are also introduced to the concept of a benchmark measurement.

Common Core Standards Addressed:
CCSS.Math.Content.4.G.A.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
CCSS.Math.Content.4.MD.C.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
CCSS.Math.Content.4.MD.C.5b An angle that turns through n one-degree angles is said to have an angle measure of n degrees.
CCSS.Math.Content.4.MD.C.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
