1. Name: ______________________________________username/pw: goddardmath Task 1: Read through the “Modeling and Solving Two-Step Equations” Lesson Info. QUESTION 1: What do you know about solving equations so far. Task 2: Identifying the Equation. The equation appears at the top of the Gizmo box ( A ). QUESTION 2: What is the equation? QUESTION 3: What operations are being done on x. List in proper order of solving. Task 3: Working with the Gizmo Use the prompts ( B ) and the directions from the Lesson Info to model the equation identified. QUESTION 4: What does the model look like? Sketch or copy/paste the Gizmo box. Task 4: Solving for x. Click on the Check button in the bottom right ( C ). The prompts will then lead you through solving for x. QUESTION 5: What is the 1st operation you are performing? Sketch the model at this point. QUESTION 6: After clicking the Check button, what is the 2nd operation you perform to solve for x. Sketch the model at this point. QUESTION 7: What do you notice about the operation order to get x by itself and the operation order you wrote in QUESTION 3. A B C

2. Task 5: Linking to algebraic steps REWRITE the original equation identified from Task 1 where the left expression is on the left of the bar and equal sign below and the right expression is on the right. = USE ALGEBRA STEPS to solve the equation above. Make sure you keep both sides of the equal sign balanced. Task 6: New equation Click the New button in the top right of the Gizmo box QUESTION 8: What is the equation? QUESTION 9: What operations are being done x. List in proper order of solving. QUESTION 10: What does the model look like? or copy/paste the Gizmo box. QUESTION 11: What is the 1st operation you are performing? Sketch the model at this point. QUESTION 12: After clicking the Check button, what is the 2nd operation you perform to solve for x. Sketch the model at this point. Task 7: Rewrite the equation from Question 8 and solve algebraically. =
