1 Video Mini Lesson

Students will  listen to a video lesson on the  slope of the line .

Student Instructions

 Teacher  will prompt students to listen to  the video and  take notes on padlet.

2 Practice

The teacher will allow students time to work on the assignment during class.  The teacher will monitor each student to ensure that they understand the concept.


Student Instructions

Students will work  in pairs on  the assignment during class.  They  will discuss solution methods and compare answers. 


3 Summary

The teacher will give a brief review of theslope of a line.  The teacher will give students different coordinates to find the slope of a line.  The teacher will then inform the students, “If any of you wants to become a carpenter, slope will be every important to them.” In final  the teacher  will ask student to complete define the slope of a line  give an  example.

Student Instructions

Student will write   their definition of the slope of a line and  give an example  by accessing  the   class room  number on    formative.
