| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

"Good morning, class! Today, we are going to learn about angles in mathematics. Can anyone tell me what an angle is? [Pause and wait for responses.] That's right! An angle is formed when two lines meet at a point. Today, we’re going to identify three types of angles: acute, right, and obtuse.
[Point to a drawing on the whiteboard.] Here is an example of an acute angle; it's smaller than 90 degrees. Next, we have a right angle, which is exactly 90 degrees, and finally, this is an obtuse angle, which is larger than 90 degrees but less than 180 degrees.
[Show different angle posters around the room.] Look at these posters that show us what each type of angle looks like. Does anyone have any questions about angles so far? [Pause for questions.] Great! Let's move on to measuring some angles."
"Now, everyone, please take a protractor from your desk. [Wait for students to get their protractors.] I’m going to show you how to measure angles with the protractor.
[Demonstrate on the whiteboard.] First, you need to line up the protractor so that the center of the hole is at the point where the two lines meet. Then, make sure one line is lined up with the zero line of the protractor.
[Draw an angle on the board with a protractor.] Now, can anyone tell me what the measurement is? [Encourage responses.] Good! It measures 30 degrees, which means it's an acute angle!
[Encourage students.] Now, it’s your turn. I want you to measure the angles I have drawn on the board using your protractors. Remember to check carefully and tell your partner what type of angle it is. Ready? Go!"
"Fantastic job measuring! Now, I have some printable cards for you. [Hand out the printable cards.] Each card has a different prompt related to angles, like identifying whether an angle is acute, right, or obtuse, or measuring angles.
[Explain the task.] I want you to fill these in individually. Take your time and remember what we've learned about angles. If you have any questions, just raise your hand, and I’ll come over to help. You have five minutes to complete this task. Let's start!"
"Time’s up! Please pass your printable cards to the front. [As students hand in their cards, observe their work.] I’m going to take a quick look at some of your cards to see how well we've understood angles today.
[Review a few cards as you walk around.] You all did an excellent job! I see many correct answers here. Keep it up!
[Provide some feedback to the class.] If you got confused with any part, don’t worry! We’ll have more time to practice these angles in future lessons."
"Before we finish, I have a homework assignment for you. [Distribute the angle worksheets.] These worksheets will help you practice what we’ve learned about angles. Remember to complete it at home and bring it back for our next session.
[Explain the instructions clearly.] Make sure to read each question carefully and try to measure some angles around your house or garden as well. This will help you in understanding how angles work in real life!
Do you all have any questions about the homework? [Pause for questions.] Alright, I’m looking forward to seeing your work next time. Have a great day!"
