Week #November 9-13
Unit of InstructionFocus 4 and 5: Solving Multi-Step Equations and The Pythagorean Theorem
Standard(s) Taught

MAFS.8.EE.3.7:  Solve linear equations in one variable:  solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.

MAFS.8.G.2.6:  Explain a proof of the Pythagorean Theorem and its converse.

MAFS.8.G.2.7:  Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.

 

Learning Targets and Learning Criteria
  • simplify equations using distributive property, combining like terms, and inverse operations.
  • solve multi-step linear equations with rational number coefficients.
  • demonstrate the relationship of the three side lengths of any right angle by the use of visual models. 
  • apply algebraic reasoning to relate the visual model to Pythagorean Theorem. 
  • determine if a given triangle is a right triangle using Pythagorean Theorem. 
  • explain a proof of the converse of the Pythagorean Theorem. 
  • apply the Pythagorean Theorem to find an unknown side length of a right triangle.  
  • identify the hypotenuse as the side opposite the right angle in a triangle. 
  • draw a diagram and use the Pythagorean Theorem to solve real-world problems involving right triangles, including three-dimensional figures. 
  • connect any two points on a coordinate grid to a third point so that the three points form a right triangle. 
  • apply the Pythagorean Theorem with the characteristics of a right triangle to find the distance between the original two points. (the distance formula is not required).
