Lesson 10.1 - Algebra * Area of Parallelograms
Objective: I can find the area of parallelograms
Area: the number of square units needed to cover an object without any gaps or overlaps
Parallelogram: a quadrilateral whose opposite sides are parallel and congruent
LEsson 10.2 - Investigate * Explore Area of Triangles
Objective: I can investigate the relationship among the areas of triangles, rectangles, and parallelograms.
Congruent: having the same shape and size
Right Triangle: a triangle that has a right angle
Acute Triangle: a triangle that has three acute angles
Obtuse Triangle:a triangle that has one obtuse angle
Lesson 10.3 - Algebra * area of triangles
Objective: I can find the area of triangles
Lesson 10.4 - Investigate * Explore Area of Trapezoids
Objective: I can investigate the relationship between the areas of trapezoids and parallelograms.
Trapezoid: a quadrilateral with exactly one pair of parallel sides.
Lesson 10.5 - Algebra * Area of Trapezoids

Lesson 10.6 - Area of Regular Polygons
Objective: I can find the area of regular polygons
Regular Polygon: a polygon in which all sides are congruent and all angles are congruent
Lesson 10.7 - Composite Figures
Objective: I can find the area of composite figures.
Composite Figure: a figure made up of two or more simpler figures, such as triangles and quadrilaterals.
LEsson 10.8 - PRoblem Solving * Changing dimensions
Objective: I can determine the effect of changing dimensions on the area of a polygon by using the strategy find a pattern.
