Solving Equations( ONE-STEP EQUATIONS)

Introduction

After your 5 years in abroad, you decided to go home. You have just been challenged by your boyfriend to figure out how much money he makes per month in his 1 year contract in a basketball league.  You have nothing to fear since you already know how to write expressions from word phrases and equations from sentences.  This Webquest will demonstrate to students how to solve one-step equations also is going to build upon those skills and by the end of this WebQuest, you will be able to solve one-step equations.

Task

Your task:

Your boyfriend just received his first contract pay in his basketball team.  You ask him "How much did you make?" He responds "10,000,000 million pesos"in a year.  You ask "How much money do you make per month?"  Your boyfriend said "I worked 50 hours per week. .  If you can figure out how much money he make per hour, He will give you "50,000 thousand pesos." 

Process

This is an independant task.  GOOD LUCK AND GOD BLESS!

1.  You will start off by reviewing how to write an equation from a sentence.  Go to these websites and follow the instructions.

Evaluation

Your performance will be evaluated in the following ways: 

1. Thoroughly answering all questions correctly using complete sentences.    

2.  Correctly writing the equation from your task, correctly identifying the coefficient found in the task equation, and correctly identifying what the variable represents in the equation.

Rubric

# 1 2 3 4 Score
Answering questions 1 - 10 correctly with thorough and complete sentences. Answered all questions with at least three correct. Answering all questions with at least five correct. Answered all questions correctly but did not use complete sentences. Answered all questions correctly using complete sentences. ____/70
Writing the task equation correctly and solving it. Had most of the parts for the equation. Not solving the equation correctly. Had all of the parts for the equation but in the wrong place, resulting in a wrong answer. Had all of the parts for the equation, in the correct places, but because of a mathematical error, the answer was wrong. The equation was written properly and solved correctly. ___/100
Answering parts b and c from their task. Had neither b nor c correct. Had one of the two correct.   Had both correct. ____/30
          Total score:__/200
Conclusion

Now that you have completed this task, you have reinforced old skills and learned new ones.  You will leave this task with the understanding and knowledge of how to solve one-step equations.  Equations are used everyday in real life.  They are used many times without people even knowing they are using them.  When you are figuring how long it will take to get somewhere or the sale price of an item (to name a few) you are using equations.
