MCPS Unit Plan Algebra 1 Unit 3: Solving Equations Learning Intention 1: I know that a solution to an equation is a value that can be substituted in for the variable to make the equation true. I can solve multi-step equations using algebraic steps. I can solve multi-step equations by graphing. o I can set the equation equal to 0, graph the equation, and find the zero(s). o I can graph both sides of the equation, find the point of intersection, and identify the x-coordinate as the solution. I can recognize when an equation has many solutions or no solution. Learning Intention 2: I understand that properties of real numbers and properties of equality provide the validations for the steps needed to simplify an expression or solve an equation. I can justify each step used to simplify an expression using a corresponding property of real numbers. o Associative property of addition and multiplication o Commutative property of addition and multiplication o Distributive property o Identity property of addition and multiplication o Inverse property of addition and multiplication o Multiplicative property of zero I can justify each step used to solve an equation using a corresponding property of real numbers or property of equality. o Addition, Subtraction, Multiplication, and Division properties of equality o Reflexive property of equality o Symmetric property of equality o Transitive property of equality Learning Intention 3: I understand that a literal equation (formula) can be solved for any variable. I can solve a literal equation for any given variable. Learning Intention 4: I understand that real-world problems can be solved using equations. I can represent a real-world problem as an equation. I can solve and interpret the solution of a real-world problem involving an equation. New Graphing Calculator Success Criteria: I can use a stored value for a specific variable to check my solution for an equation. I can graph both sides of an equation and find the point of intersection. I can use nSolve to solve an equation. I can test additional values for a variable if nSolve returns a solution of 0.
