Student reflections in Math: Geometry (shared via Gapps)

We started with an exploration task.

Since both the grade 7s & 8s are learning about bisectors and geometric properties [specifically angles in a triangle (7/8) & angles created by intersecting lines (8)]; it's a good idea to get students thinking about what they've already learned, while getting familiar with the tools used commonly when exploring geometry (compass, ruler, protractor, etc.)

Grade 8s started with an exploration about constructing circles using ONLY the compass, while provided with a) centre and a point on the circle; b) centre and the radius; c) three points on a circle;  Students were expected to discover that the opening of the compass is the radius of the circle; and they also began to question whether there's a connection between the centre of a circle and the centre of a triangle.

Grade 7s started with an exploration about angles; they were provided with a sheet of paper, with no tool allowed, and were asked to construct three angles: 30, 45, and 60 degrees, as accurate as possible.  Students were expected to discover the purpose of angle bisectors, while activating their background knowledge about angles.

Both grades then continued with an investigative activity (finding the midpoint of a line segment) and began to think about bisectors.

How does these concepts relate to our lives?  What are some real-life applications involving bisectors, angles, and geometric properties?

Looking forward to hear your feedback~

We are now entering our Geometry unit (both grade 7 & 8) in all three classes.  You can see a brief unit overview here.  We will be exploring angles, shapes, geometric attributes for 2- & 3-D figures, and learn to construct and manipulate these figures using a variety of tools, especially compass, ruler, protractor, and etc.

What are some of your background knowledge in Geometry?  What have your learned in the past? What do you wish to clarify this time around?  What are some of the challenges your have experienced in the past learning?  Share with us and we can learn from each other!

To parents:  You can get involved!  Simply start a conversation about how tools of measurements are used in your daily life and around the household.  You can also share what you know (ie. constructing a shape) with your children.

Students will also start constructing Google Sites that outline/document our learning in this unit!  Stay tuned!

Hey everybody, just a reminder that classroom photos will be on Monday, November 5th, don't forget your SMILE:)
