Parent Newsletter Math News Grade 5 - Unit 6 Geometry Math Makes Sense Dear Parent or Adults at Home … Your child’s class is starting a mathematics unit on geometry. Geometric shapes are in the world all around us, and mathematics can help your child recognize important features of geometry. Recognizing geometric features and understanding geometric form are key steps in developing a higher level of mathematical thinking. In this unit, your child will: Build, represent, and describe geometric objects and shapes Identify and sort quadrilaterals (that is, shapes with 4 sides) Ways Parents Can Help 1. Ask your child to show you what he/she is learning in math. 2. Help your child to learn the words to know in this unit. Geometric shapes and objects can be found outside the classroom. Encourage your child to look for geometric shapes and objects around the home and neighbourhood, and talk about them. Here are some suggestions for activities that you can do at home: Look for geometric shapes in buildings and street signs. For example, a stop sign has the shape of an octagon, and a yield sign has the shape of a triangle. Find objects around the house that have different shapes. For example, a tissue box or a cereal box has the shape of a rectangular prism. Ask your child to tell you the differences between the objects. 3. Invite/encourage use of the vocabulary and concepts to real world situations. 4. Take a look at the Unit Review. Sample Problem Answer each riddle. a) I have two pairs of parallel sides. All my sides are equal. All my angles are right angles. What am I? Math Links and Resources b) I have 4 sides. I have only 1 pair of parallel sides. What am I? http://www.hzsd.ca/Learningc enter/library/Math%20Resour ces/Grade%205%20Math%20 Websites c) I have 2 pairs of equal sides. I have no parallel sides. What am I? Sask Ministry of Education Outcomes SK SS5.5 Describe and provide examples of edges and faces of 3-D objects, and sides of 2-D shapes that are: parallel intersecting perpendicular vertical horizontal. [C, CN, R, T, V] SK SS5.6 Identify and sort quadrilaterals, including: rectangles squares trapezoids parallelograms rhombuses according to their attributes. [C, R, V] Words to Know: Attribute: A characteristic, e.g., shape, size or colour. Parallel: Two lines that are always the same distance apart are parallel. Intersect: For shapes, when 2 sides meet, they intersect in a point called the vertex. For objects, when 3 or more edges meet, they intersect in an edge. Vertex: The point where 2 sides of a shape meet. The point where 3 or more edges of an object meet. Horizontal: A line that is parallel to the horizon. Vertical: A line that is perpendicular to the horizon. Perpendicular: Two lines that intersect at a right angle are perpendicular. Right angle: Two lines that are perpendicular make a right angle. Diagonal: A line segment that joins opposite vertices of a shape. Rhombus: A quadrilateral with all sides equal and 2 pairs of opposite sides parallel. Parallelogram: A quadrilateral with 2 pairs of opposite sides parallel. Trapezoid: A quadrilateral with exactly 2 pair of sides parallel. Kite: A quadrilateral with 2 pairs of adjacent sides equal.
