TIPS4Math Grade 4 Angles and Geometric Properties of 2D Shapes Overall Expectation Students will: • Identify quadrilaterals and three-dimensional figures and classify them by their geometric properties, and compare various angles to benchmarks (4m58) Specific Expectations Students will: • Draw the lines of symmetry of two-dimensional shapes, through investigation using a variety of tools and strategies (4m61) • Identify and compare different types of quadrilaterals (i.e., rectangle, square, trapezoid, parallelogram, rhombus) and sort and classify them by their geometric properties (4m62) • Identify benchmark angles (i.e., straight angle, right angle, half a right angle) using a reference tool, and compare other angles to these benchmarks (4m63) • Relate the names of the benchmark angles to their measures in degrees (4m64) Lesson Benchmark Angles Lines of Symmetry Quadrilaterals Learning Focus • • • • • • Identify benchmark angles using a reference tool Relate the names of benchmark angles to their measure in degrees Compare other angles to benchmark angles Through investigation, draw lines of symmetry of 2D shapes using a variety of tools and strategies (mira, paper folding, grid paper) Identify and compare different types of quadrilaterals Sort and classify quadrilaterals by their geometric properties (side length, angle size, parallel lines, lines of symmetry) Specific Expectations 4m63 4m64 4m61 4m62 Consolidation and Summative Tasks EduGAINS-Mathematics Page 1 of 7 TIPS4Math Specific Expectations: 4m63, 4m64 Learning Focus Minds On • Review
