1 Direct Instruction

Activity: Exploring


  • Learners explore the classroom or playground asking them to draw what kids of lines they see. 
  • Learners then have various triangles in photos or manipulatives (acute, obtuse and right) and examine what they notice. They may draw, write, sort the triangles any way they like but need to be able to justify
  • Teacher may want to preteach or review terms such as vertices, lines, sides.
Student Instructions
  • Look around the classroom/playground. What things do you notice? What sort of shapes are there? What do you notice about these shapes? (They are made from lines). How are the lines connected? 
  • Now look at the triangles. What do you notice?  Sort them anyway you can.
  • Justify how and why you have made your decisions to another group . Report to the class.

2 Guided Practice

Activity: Investigating
  • Students play the straws and create different angles.
  • Teacher led demonstration on how to make the different angles.
  • Lexis (obtuse, right, straight and acute) angles are demonstrate.  
  • Teacher to introduce straws and twist ties demonstrating to learners how to use 2 straws with 1 twist tie inserted into both  to make a flexible angle. Students then explore, bend twist. 
    Learners then are asked to draw/trace the different angles (although we have not identified as angles yet) on a large paper.

Student Instructions

Students play and are engaged with making different angles using straws

  • Now take 2 straws and a twist tie and connect the straws by inserting the twist tie in both straws. Have a play and see what you can make. 
  • Now draw some of the things (lines) you made with the straws. You may trace or copy. What do you notice? Are they all the same? What is different or the same about them? Can you see any of these lines or shapes in our classroom?

3 Independent Practice

  • Students should have a digital camera/or tablet with a camera (iPad, Tab)
  • Teacher allows learners to explore with straw connectors asking learners to take photos of the different angles as they identify them.
  • Learners create a new Book Creator Book using the Book Creator App and upload the images of the angles they took photos of (acute, straight etc..). 
  • Students then record their explanations on each of the angle images they uploaded.
  • A teacher/student generated rubric could be complied about the learning goals (ie angles taught in mini lessons)  to assess the understanding of angles. The rubric may also contain design/presentation criteria
  • The rubric can be used as a peer evaluation tool before publishing. 
  • Learners then publish the Angle iBook that could be uploaded to iTunes and shared on a class or individual blog for sharing to authentic audience
Student Instructions
  • Students open Book Creator and make a new book withthe title 'Angles'.
  • Upload the photos taken from the straw, angle engagement. These could be shared to a global audience on blogs, webpages or within a school community
  • Learners then have a chance to use IXL.com on Angles for further practice.
