Activity 13

 Pick up a Notecard and write your NAME and PERIOD  Title Notecard: GOALS  Answer the following questions:  1. What do I want to improve upon this six weeks in math class?  2. How can I make sure I accomplish this goal?  Who will help hold me accountable? (other then the teacher)

Learning Targets How many solutions are in an equation? An equation is like a… Today I can… 1.Write a one-step addition equation to model a situation 2.Solve an addition equation An equation only has one solution, the variable can only have one value.

How do you keep things balance? Inverse Operations When solving an equation you are trying to… How do you isolate the variable? “What you do to one side you do to the other” Operations that “undo” each other. For example subtraction “undos” addition and addition “undos” subtraction Isolate the variable, get the variable on one side by itself Use inverse operations

 Write these in your notes for today  1. A soccer team has 11 players. There are 9 players on the field. Write an equation to represent the situation so that you may find how many players need to be on the field for the team.  2. Solve the following: 10.5 = x

Learning Targets What is an inverse operation? Steps to Solve Equations Today I can… 1.Write an equation from a word problem 2.Solve a subtraction equation Operations that “undo” each other. For example subtraction “undos” addition and addition “undos” subtraction (Only Read this statement. Do not write) 1.Locate the variable (highlight or circle) 2.Isolate the variable (get it alone) 3.Use Inverse Operations to isolate 4.Check Point (Check the solution)

 P. 167 # 1 & 2

 A volleyball team has 6 players on the court during a game. This is 3 times the number of players on the court in beach volleyball. Find the number of players on the court during a beach volleyball game.  1- How would you solve this problem?  2- Try to write an equation that represents this situation.

Learning Targets What would be the inverse operation of multiplication? Coefficient Steps to Solve Equations Today I can… 1.Write multiplication equations to represent situations. 2.Solve a multiplication equation Division -To isolate the variable in a multiplication equation you DIVIDE both sides of the equation by the coefficient of x. Is a number that multiples a variable EX. 4x (4 is the coefficient) 1.Locate the variable (highlight or circle) 2.Isolate the variable (get it alone) 3.Use the Inverse Operations of Division to isolate 4.Check Point (Check the solution) Practice: 3x = 2109x = 108

How do we solve multiplication equations with fractions? Practice Define Variable Write Equation Solve Equation Check Solution

 A punch recipe makes 24 servings of 6 ounces each. How many total ounces of punch does the recipe make?  1- Define the variable.  2- Try to write an equation that represents this situation.

Learning Targets What would be the inverse operation of division? Steps to Solve Division Equations Today I can… 1.Write division equations to represent situations. 2.Solve a division equation MULTIPLICATION -To isolate the variable in a division equation you MULTIPLY both sides of the equation by the denominator. 1.Locate the variable (highlight or circle) 2.Isolate the variable (get it alone) 3.Use the Inverse Operations of multiplication to isolate 4.Check Point (Check the solution)
