Unit 1 - Day 1:

Day 1:

Daily Objective: Students will learn the area of squares, rectangles, triangles, trapezoids, parallelograms, circles, and polygons. Students will define point, line, plane, line segment, ray, angle, median, altitude, and perpendicular .

Definitions:

Line: The path of a point moving in opposite directions infinitely. It is the distance between two points.

 Plane: A flat surface that can extend in length and width but has no thickness.

Line Segment: Part of a line between two points, called end points. 

Ray: It is a straight line that extend from an end point and does not connect to another. 

Angle: The figure formed by two rays from the same initial point. The two rays are called the sides of the angle and the initial point is called the vertex of an angle.

Median: The line segment from a vertex of a triangle to the midpoint of the opposite side.

Altitude: The perpendicular distance from one side (called the base) to the farthest point. The dotted line shown in the figure is the altitude of a triangle.

Perpendicular: Two lines that intersect at right angles.

Area:

Square - B x H 

Rectangle - L x W

Triangle - B x H / 2

Parallelogram - B x H 

Circle - Radius Squared x Pi 

Polygons - 1/2 Apothem x Permimeter

Quiz 1: 

Quiz 1: Answers :

Question 1- Find the area of the kitchen.
       step 1: 25 x 15 = 375un
       step 2: 2 x 5 = 10un
       step 3: 375 + 10  = 385 un squared

    Answer: 385" squared

Question 2 - Find the area of a polygon.
       step 1: 7 x 8 = 56 in
       step 2: 56 x 6 (6 is half the apothem) = 336 in

    Answer: 336" squared

Question 3 - Find the area of the triangle below.
       step 1: 7 x 10 = 70 in
       step 2: 70 / 2 = 35 in

    Answer: 35" squared
