Our next math unit!!!

This week we will start a new math unit – angles and shapes! We will be focusing on these geometric concepts for the next couple of weeks.

UNIT: Angles and Shapes

BIG IDEAS (taken from “Big Ideas by Dr. Small”):

• Some attributes of shapes are quantitative, others are qualitative.
• Geometric shapes can be classified and sorted according to attributes.
• The measurement of an angle is defined by how much one arm turns around a vertex relative to the other arm.

STUDENT LEARNING GOALS:

• I can classify angles and construct them up to 90°
• I can classify triangles based on both angles and side lengths.
• I can construct a triangle based on specified criteria.
• I can classify polygons.

CURRICULUM EXPECTATIONS:

• distinguish among polygons, regular polygons, and other two-dimensional shapes
• identify and classify acute, right, obtuse, and straight angles;
• measure and construct angles up to 90º, using a protractor;
• identify triangles (i.e., acute, right, obtuse, scalene, isosceles, equilateral), and classify them according to angle and side properties;
• construct triangles, using a variety of tools (e.g., protractor, compass, dynamic geometry software), given acute or right angles and side measurements (Sample problem: Use a protractor, ruler, and pencil to construct a scalene triangle with a 30° angle and a side measuring 12 cm.).
