Transformations and Symmetry
Our latest unit once again involves a lot of hands on work for the students! They will be using many different types of manipulatives to explore how figures are moved or transformed. In this unit, your child will;
1) Describe movement on a grid (how many squares left, right, up, or down - no diagonal movement on a grid)
2) Explore slides (translations), turns (rotations), and flips (reflections)
3) Perform translations, rotations, and reflections with concrete materials and pictures
4) Explore lines of symmetry in everyday figures, as well as figures they will create on paper using a transparent mirror
Here is some information to remember
A translation (slide) can move horizontally (to the left or right), vertically (up or down), or diagonally (on a slant). The way the object faces or looks never changes.
A rotation (turn) can rotate a figure clockwise or counterclockwise. We will be practicing rotations that move an object in one of the following ways ( a quarter turn, a half turn, a three-quarter turn) A good way to remember what these turns would look like is to think about the minute hand on a clock, moving from the 12 to the 3 to the 6 to the 9.
A reflection (flip) can reflect a figure horizontally or vertically. Pay close attention to how far the original object is from the mirror line. The reflected object needs to be the exact same distance away but on the other side of the mirror line. The reflected image will look identical in size and shape to the original object but they will face opposite ways.
A line of symmetry divides a figure into two congruent parts, so that the two parts will match when the figure is folded along the line of symmetry. Some figures have no lines of symmetry while other figures have one or more lines of symmetry.
