Direct student attention back to the class list generated in #2, above.Have students create vocabulary index cards with drawings and definitions for each of the bolded words on the worksheet vertex, degrees, right angle, obtuse angel, and acute angle.Draw examples of a straight line, right angle, acute angle and obtuse angle on the board or overhead. Guide students through each bullet on the worksheet. Next, provide each student with a copy of the Angle Facts Worksheet (PDF).Create a class list of angles on the board, flipchart, or overhead: Gather the class and ask each team to share two examples of angles.The list may include the following: bike wheel spokes, pizza slices, clothing hangers, binders, hands of a clock, a playground slide, an open door, door stopper or wedge, chair, and even a pencil is held at an angle when used for writing.
