The students will be having their end of unit quiz on their 2-D shapes unit of math on Monday, December 5.
Grade 4 students will have to be able to show the following:
-identify benchmark angles (right angle, half a right angle, straight angle) and compare other angles to these benchmarks (greater than a right angle, less than a right angle but greater than half a right angle, or less than half a right angle)
-relate benchmark angles to their measurement in degrees (right angle is 90 degrees, straight angle is 180 degrees, half a right angle is 45 degrees)
-identify and draw the lines of symmetry in 2-D shapes
-identify and compare different quadrilaterals (trapezoid, parallelogram, rhombus, rectangle, square) and sort and classify them by their geometric properties (side lengths, parallel sides, equal sides, angle descriptions.
Grade 5 students will have to be able to show the following:
-identify acute, obtuse, right, and straight angles
-measure and construct angles up to 90 degrees using a protractor
-distinguish between polygons, regular polygons, and other 2-D shapes
-identify triangles by their angles (acute, right, obtuse) and by their sides (equilateral, isosceles, scalene)
-construct triangles (using a protractor and ruler) given the angle and side measurements
Please have students review these ideas and practice these skills this week in preparation. Students can come and see me for extra help or practice at different times during the day.
