Lesson Plans (1) A detailed description of the instruction for teaching one or more concepts or skills. Learning Activities (2) Building blocks of a lesson plan that include before, during, and after strategies to actively engage students in learning a concept or skill.


ALEX Lesson Plans  
   View Standards     Standard(s): [MA2015] (6) 11 :
11 ) Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate. [6-NS8]

[MA2015] (6) 25 :
25 ) Recognize a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers. [6-SP1]

Example: "How old am I'" is not a statistical question, but "How old are the students in my school'" is a statistical question because one anticipates variability in students' ages.

Title: Michael Phelps.... or not?
Description:

This lesson is created to have students compare themselves to Michael Phelps and the features that make him such a good swimmer. Students will measure their height and arm span and graph them on a coordinate graph. Students will then compare their height and arm span to their classmates' to see who might be the best swimmer in the class!

This is a College- and Career-Ready Standards showcase lesson plan.

8 ) Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b. [8-EE6]

[MA2015] (8) 10 :
10 ) Analyze and solve pairs of simultaneous linear equations. [8-EE8]

a. Understand that solutions to a system of two linear equations in two variables correspond to points of intersections of their graphs because points of intersection satisfy both equations simultaneously. [8-EE8a]

b. Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. [8-EE8b]

Example: 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.

c. Solve real-world and mathematical problems leading to two linear equations in two variables. [8-EE8c]

Example: Given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair.

[MA2015] (8) 13 :
13 ) Interpret the equation y = mx + b as defining a linear function whose graph is a straight line; give examples of functions that are not linear. [8-F3]

Example: The function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4), and (3,9), which are not on a straight line.

[MA2015] (8) 23 :
23 ) Apply the Pythagorean Theorem to find the distance between two points in a coordinate system. [8-G8]

[MA2015] (6) 11 :
11 ) Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate. [6-NS8]

Subject: Mathematics (6 - 8)
Title: Graphville Shopping Excursion
Description:

Students will create a map of a shopping excursion by solving systems of linear equations through graphing, substitution, or elimination. Students will then be able to determine the distance traveled through the mall using Pythagorean Theorem. Students will utilize previous grade level standards as a spiral review such as plotting coordinate pairs and using those pairs to find the distance between two points.

This activity is a result of the ALEX Resource Development Summit.




   View Standards     Standard(s): [MA2015] (5) 24 :
24 ) Represent real-world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation. [5-G2]

[MA2015] (6) 11 :
11 ) Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate. [6-NS8]

Subject: Mathematics (5 - 6)
Title: Treasure Map Graphing
Description:

Students lead a quest for buried treasure in this geometry game. Students must follow clues to identify x- and y-coordinates on a treasure map, to lead them around the island before landing on the pirate booty. Students will also graph points on the coordinate plane.  

This activity results from the ALEX Resource Gap Project.
