Maths Angles.mp4Direct Instruction: Table Angles in Maths
Students are identifying types and features of different angles and learning how to measure angles accurately.
This video shows a whole class lesson on angles that can be used as a pretest to help sort students into future groups for learning.
Reflection: With trying to inspire students to learn more about maths I saw this lesson set up in another class and decided to have a go. You know how students and are told no writing on tables - well here is a constructive way to do it. All students were engaged with identifying angles and measuring them. This was a second attempt at the lesson as we had so many away the first time and most of them still enjoyed it. This lesson was lots of fun with drawing/writing on tables and hands on learning. Showing students the value of measuring all angles to prove that angles opposite each other, helps to enhance their own learning and justification, so they are not just guessing.
Things to note: I had done this lesson earlier in the week but many students had been away. When I started the learning intentions and success criteria were on the screen, unfortunately we have issues with casting and it not always staying on the screen. That is why we can back to it part way through the lesson, which is not a bad thing to do anyway. We did discuss how to use a protractor, however that was not recorded in this lesson. We also discussed the feature of the different angles but I only kept a couple in the recording.
After seeing tables covered in tape with measured angles written in whiteboard marker I knew I had to give it a go.
Students were excited to see tables covered in tape, anything on tables often means something different is happening.
We talked about shapes and what angles you can find with different shapes - helping students to access prior knowledge such as 90 degrees.
Instructions:
Cover tables with masking tape, ensure you have a range of angles: acute, right, reflex and obtuse. Tape can intersect giving the opportunity to discuss angles that are opposite each other. Other ideas are complementary and supplementary angles.
Once you have a list of the different the angles and have discuss or listed the features of each, create a code, students can record these easier.
Then students can create theories about angles once they have measure all the ones on the table.
