Topic: 11.1 Area of Parallelograms and Triangles What are we learning? Daily Objective:

I will be able to find the area of a triangle and parallelogram and apply Heron’s formula to find the area of a triangle.

TEKS/AP/Standards:

G.1.A: Develop an awareness of the structure of a mathematical system, connecting definitions, postulates, logical reasoning, and theorems

G.5.A: Use numeric and geometric patterns to develop algebraic expressions representing geometric properties

G.8.A: Find areas of regular polygons, circles, and composite figures

G.8.C: Derive, extend, and use the Pythagorean Theorem

How will we learn it? Learning Activities:

Students will apply the area of parallelogram formula (review).

Students will be introduced to the Heron’s formula and will apply it to find the area of a triangle.

How will we tell if we’re learning it correctly? Assessment Methods:

Guided Practice Problems Checks for Understanding:

Teacher will be walking around while the students are working on practice problems.

Topic: 11.3 Perimeter and Area of Similar Figures

What are we learning? Daily Objective:

I will be able to discover the effect of perimeter and area when dimensions of similar figures.

TEKS/AP/Standards:

G.8.A: Find areas of regular polygons, circles, and composite figures.

G.11.B: Use ratios to solve problems involving similar figures.

G.11.C: Develop, apply, and justify triangle similarity relationships, such as right triangle ratios, trigonometric ratios, and Pythagorean triples using a variety of methods.

G.11.D: Describes the effect on perimeter, area, and volume when the dimensions of a figure are changed and applies this idea in solving problems.

How will we learn it? Learning Activities:

Students will work with their shoulder partner to discover the effect on perimeter and area when dimensions of a figure are changed.

How will we tell if we’re learning it correctly? Assessment Methods:

Student explain their findings from activity. Checks for Understanding:

Students will be called up to the board to fill in their answers and explain what they discovered about the effect on perimeter and area when dimensions of a figure are changed.

Students will apply what they learned to a real-life application problem.
