Teacher Notes Subject: Math Topic: Geometry Title: Angles Grade(s): 5 and 6 Cross-curricular link(s): Nonspecific Intended learning outcome(s) · Students identify the parts and types of angles · Students measure and create angles with specific measurements · Students recognize angles in real-life objects Recommended usage: There are two pictures in the "Attachments" section that I took around my school. You can add to those pictures or use you own. I took pictures of teachers making angles with their arms and legs. "Teacher Says" is just a game that I use to review, you can delete the slide if you do not want to play the game.

An angle measuring exactly 90 degrees. Move to see answer. Move to see answer. Straight Obtuse An angle measuring more than 90 degrees. Move to see answer. An angle that measures exactly 180 degrees. Move to see answer. Label the following angles... Acute Right Obtuse How do we measure angles? Some things to notice: * Line up the vertex to the circle in the center of the protractor. * There are two sets of numbers (moving opposite directions). Either can be used. * You can draw your own angle using a protractor or you can measure other angles. Using a protractor. Here are some angles to practice on. Draw angles at the following degrees: 32 104 78 165 10 98 Find the angles in the pictures. Now, measure the angles in these pictures of real items. מצאו שלוש נקודות היוצרות זווית הכי קטנה שאפשר פתרון הוסיפו נקודה ירוקה על אחד הקדקודים ברשת ,כך שאם מחברים אותה לשתי נקודות צהובות מתקבלת זווית ישרה בקדקוד הירוק
