Remote Learning Lesson: Angles (Measuring and Recording on an iPad) for Years 4 & 5

0
1057

Summary of Lesson Plan:

The following lesson allows students to explore angles either in distance learning format (around the home) or within their school. Students will be exploring a range of angles using technology to record, take images and to draw the angles over the top of images. Students can also access AR (augmented Reality) apps for tablets in order to measure real life angles using degrees.

As students finish each section they can email or upload it to their teacher using a program set up within the school.

Mathematics (Measurement and Geometry):

Year 4:

  • Compare angles and classify them as equal to, greater than, or less than, a right angle
  • Creating angles and comparing them to a right angle

Year 5:

  • Estimate, measure and compare angles using degrees. Construct angles using a protractor
  • Measuring and constructing angles using both 180- and 360-degree protractors
  • Recognising that angles have arms and a vertex, and that size is the amount of turn required for one arm to coincide with the other.

Essential Questions:

• What are angles?
• What are the different types of angles?
• How do we measure angles?
• Where do we see real life examples of angles?

Skills Developed:

• Classify different angles.
• Measure and construct different angles.
• Classify angles in relation to right angles.
• Use technology to document different angles.
• Explain mathematical thinking.

Lesson Plan Sequence:

Introduction to Angles

Focus: What do we know | What are angles?

  1. Question- what do you know about angles?
  2. Watch video: Intro to angles for kids
  3. Angles notebook: Students to complete

Angles Tasks

Students to complete these tasks at home at their own pace. Once completed students will upload their work to the student in a format of the teachers choice (e.g. Google Drive, Microsoft Teams etc.)

Focus: Angles in our homes

Part 1: Comparing angles to right angles

Task: To find and take photos of different angles you can find around your house and outside.

Steps:

  1. Take photos of different angles you can find (greater than, smaller than and equal to right angles)
  2. Use an application to draw over the angle (notes, explain everything, book creator or print and draw on them)
  3. Classify the angles as greater than, equal to or smaller than a right angle

Part 2: Measuring and classifying angles

Task: To find and make different angles using objects around your house and outside.

Steps:

  1. Take photos of different angles you can find in and around the house. Use your body and different objects to create different angles.
  2. Download an application to measure the degrees in images (Angles in Photo)
  3. Classify the angles as acute angle, right angle, obtuse angle, straight angle and reflex angle

Closing & Follow up

Focus: Share findings

Part 3: Reflection

Task: To create a video reflection explaining what you have learned

Explain in my video reflection:

  1. What is an angle?
  2. What is a right angle? How do you know if an angle is greater than or less than a right angle?
  3. What are the different types of angles? Can you give examples?
  4. What is something interesting you learned?
  5. What questions do you still have?

Apps & websites to use to further explore angle learning:

  1. IXL: website- you can practice 10 free questions a day (click Maths and choose angles in measurement subheading)
  2. Targeting Maths (Paid- $9.99) buy in students year level. I highly recommend this app as you can practice all areas of Mathematics curriculum. For angles- Training – Measurement – angles
  3. Drone Angles: App (free)
  4. Angles ball game: App (free)
  5. Crickweb Angles: online (free)
  6. Angles quiz: Maths is fun (free)
