Mathematics and kitchen - Know Thy Fractions

So you think that mathematics is not useful for everyday life is? What's in the kitchen, Mrs. Dash the tasty baked chicken dish east? You know that that requires a 1 tbsp. Mrs. Dash Extra Spicy seasoning mix, 6 (4 ounce) boneless skinless chicken breast, 2 / 3 cup plum sauce and 1 tablespoon oriental. lite soy sauce. Now, this recipe calls for 6 chicken breasts. So, what do you do when you have only four? Read on.

The knowledge of mathematics has made ​​me many advantagesin life that would be too numerous to mention here. In addition to feeling more than sufficient in everything I do, gives me the advantage when it comes to mathematical problem solving, strategy development, planning, and yes, even cooking! In the previous recipe, the problem of a reduction in the Ingredients 4 chicken breasts is to accept and a sixth in terms of fractions, it means you have 4 / 6 or 2 / 3 of the chicken needed. To adjust the recipe so that everything remains the same circumstances, we needtake 2 / 3 of the other ingredients. Ah, the hell fractions!

A big problem. To adjust the other ingredients that we have, 2 / 3 multiplied by 1 tablespoon. Extra spicy seasoning mixture and soy sauce and lite. This is easy. The adjustment is 2 / 3 tablespoons. two, or a little 'less than full Essl. But what to do with the cup 2 / 3 of the oriental plum sauce? Now we have 2 / 3 of Take That, or we would drown our 4 chicken breast fillets in plum sauce and chicken with plums at the endBaked chicken instead of east. Well, if we consider how to multiply fractions, it is easy. Just multiply the numerator and denominator together, from 4 / 9 of a cup. Since 2 / 3 as a decimal number is about 0.66 or 66% and 4 / 9 is 0.44 or 44%, you need a little 'less than half a cup. If your cup markers is 1 / 16 's, then you have to fill the line below a half a glass, get the amount of plum sauce.

So you see, the mathematical fact has its advantages. And if you do notreally going to use for this unusual topic to solve a problem in nuclear physics, at least you can use to help with something more practical problems, how to answer the question: "What should I do for dinner?" Who knows, if you master this topic enough, you can end up like Emeril.

Here's to good eating!

"With the collaboration of a number of dedicated teachers and their students, Susan Empson and Linda Levi have produced a volume that is faithful to the basic principles of CGI while at the same time covering new ground with insight and innovation."

-Thomas P. Carpenter

This highly anticipated follow-up volume to the landmark Children's Mathematics: Cognitively Guided Instruction addresses the urgent need to help teachers understand and teach fraction concepts.Fractions remain one of the key stumbling blocks in math education, and here Empson and Levi lay a foundation for understanding fractions and decimals in ways that build conceptual learning.They show how the same kinds of intuitive knowledge and sense making that provides the basis for children's learning of whole number arithmetic can be extended to fractions and decimals.Just as they did in Children's Mathematics and Thinking Mathematically, Empson and Levi provide important insights into children's thinking and alternative approaches to solving problems. Three themes appear throughout the book:

• building meaning for fractions and decimals through discussing and solving word problems
• the progression of children's strategies for solving fraction word problems and equations from direct modeling through relational thinking
• designing instruction that capitalizes on students' relational thinking strategies to integrate algebra into teaching and learning fractions.

With illuminating examples of student work, classroom vignettes, "Teacher Commentaries" from the field, sample problems and instructional guides provided in each chapter, you'll have all the tools you need to teach fractions and decimals with understanding and confidence.
