For the month of January, we will be learning about 2D geometry. Read below for an overview! Big Ideas for Geometry (Location & Movement) -Transformational geometry can be used to understand and represent locations/directions. -A transformation is a ‘motion’ (translation - slide, reflections - flip, rotations - turn). -Transformations of 2D shapes can result in figures that are similar or congruent to the original figure. -Congruent shapes have identical side lengths, angles, perimeters and areas. -Transformations are often observable in our everyday natural world. Geometry (Location & Movement) -Plot points in 1st quadrant of Cartesian plane -Rotations of 90 and 180, clockwise and counter-clockwise, with center of rotation inside and outside of shape *A focus for Gr 6s (they will be doing this in more depth) -Reflections (flips) and translations (slides) -Identify translations that map congruent shapes onto each other A lot of this 'spirals' back to our geometry learning about triangles and quadrilaterals, so we'll be reinforcing those concepts too as we move forward. Students enjoyed finding the co-ordinates of our Canadian Prime Ministers ("St Laurent was a PRIME MINISTER? I thought it was just a SHOPPING MALL!" #LoveThis). See photos below! Students also created a scalene, obtuse triangle on a geoboard, hid it from their partner, and gave the coordinates of each vertice. Then they checked that they had congruent polygons. This was a great activity to use a lot of math vocabulary! Students enjoyed a battleship type game where they 'hid treasure' - and of course, found it using coordinates. A note about extensions: below are photos of math extensions, designed to be a) on topic with what we are currently learning and b) take your child further in math. Some are fun/easier and others are fun/much harder. The expectation is that if students are done their math work early, they work on a math extension. Up Next: transformations, including translations, reflections and rotations.

Mrs JorgensenI'm a math nerd and think math jokes are funny. Not all of them though - just sum. Archives
