Math Dough

 
Introduction:  
  Fractions are mathematical concepts that are applicable to life in many ways. In fact, you have probably been learning about fractions for several years. Fractions play a part in your life even outside of the classroom. Sometimes, when working recipes the listed ingredients are only for one person. What if you were making the recipe for your entire family? What if the recipe states that you need � a cup of sugar and you need the recipe for more than one person? Knowing how to add fractions will certainly come in handy when you need to make a one person recipe enough for you entire family. First, we need to remember the many different rules about adding fractions.
Task:  
  We are going to learn about adding fractions using a number of resources. With the handout you received in class, the internet, and personally created recipe cards we are going to explore everything we need to know about adding fractions. The handout will follow along with this WebQuest and help you keep your thoughts and results organized.
Your journey through the WebQuest will enable you to answer the following questions: Which part of the fraction is the numerator and which part of the fraction is the denominator? How do you add two fractions with the same denominator and different numerators? The least common denominator is simply the least common multiple of denominators. Therefore, how are we going to find the least common denominator of a given set of fractions? How do we add two fractions with different denominators? You will observe a recipe to make play dough but the recipe will be for one person. You are going to make a personal recipe card which will include the recipe you need in order to make enough play dough for you and your family.

5) Lastly, use your new family play dough recipe to create a personal recipe card for you and your family. Make sure your unique recipe card includes the necessary ingredients your family will need and dont forget to include the steps too!
