# Q2 W4 Nov 4-8 Pre-Algebra Teacher Stephanie Durrance 8th Grade Math (Pre-Algebra) 8th 4 Unit 4: Linear Equations, Functions, and Inequalities
Standard(s) Taught
 MAFS.8.EE.3.7: Solve linear equations in one variable.  a. Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions.  Show which of these possibilities is the case by successively transforming the given equation into simpler forms until an equivalent equation of the form x=a, a=a or a=b results (where a and b are different numbers). b. 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 it 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
 a.       • solve a linear equation with one solution, no solution, and infinitely many solutions.  • explain the when an equation has one solution, no solution, and infinitely many solutions.     b.      • simplify equations using distributive property, combining like terms, and inverse operations.  c.       • solve multi-step linear equations with rational number coefficients.  d.      • apply the Pythagorean Theorem to find an unknown side length of a right triangle.   e.       • identify the hypotenuse as the side opposite the right angle in a triangle.  f.        • draw a diagram and use the Pythagorean Theorem to solve real-world problems involving right      triangles, including three- dimensional figures.  g.      • demonstrate the relationship of the three side lengths of any right angle by the use of visual models. h.      • apply algebraic reasoning to relate the visual model to Pythagorean Theorem. i.        • determine if a given triangle is a right triangle using Pythagorean Theorem.
