The "Geometry and Spatial Sense" activity packet is aligned with the Ontario Grade 3 Mathematics curriculum expectations. This activity packet is great for high flying Grade 2 students or students in Grade 4 who need more assistance. This activity packet addresses 2D and 3D geometry.
The activity packet addresses the following expectations:
• Use a reference tool to identify right angles and to describe angles as greater than, equal to, or less than a right angle;
• Identify and compare various polygons and sort them by their geometric properties;
• Compare various angles and describe angles as bigger than, smaller than, or about the same as other angles;
• Compare and sort prisms and pyramids by their geometric properties;
• Construct rectangular prisms and describe geometric properties of the prism;
• Solve problems requiring the greatest or least number of two-dimensional shapes needed to compose a larger shape in a variety of ways;
• Explain the relationships between different types of quadrilaterals;
• Identify and describe the two-dimensional shapes that can be found in a three-dimensional figure;
• Describe and name prisms and pyramids by the shape of their base;
• Identify congruent two-dimensional shapes by manipulating and matching concrete materials;
• Describe movement from one location to another using a grid map;
• Identify flips, slides, and turns, through investigation and name flips, slides and turns and as reflections, translations, and rotations;
• Complete and describe designs and pictures of images that have a vertical, horizontal, or diagonal line of symmetry.
It is important to note that although students learn about angles in this packet, they do not use a protractor. Instead, students construct a right angle tool and use this tool as a point of reference. If you have any questions, please feel free to contact me!
