Quick Guide to the Common Core: Key Common Core Expectations Explained - Mathematics - Vander Ark on Innovation Guest blog by Kathy Kellman, executive editor of mathematics at Curriculum Associates Note: This is part two of a two-part series. Last week, my colleague Adam Berkin wrote the first part in this series, " Quick Guide to the Common Core: Key Common Core Expectations Explained " for the English Language Arts standards. A lot of people (including some educators) have a lot of anxiety about math: How do we teach it? How do we learn it? How do we remember it all and use it correctly in real life? All of mathematics is built on a few basic ideas. Following are some of the key differences between the new standards and many of the current educational standards in place around the country. Narrower and deeper focus in each grade The Common Core standards for math were designed to focus instruction on fewer topics each year, allowing more time to be spent on each topic to foster deeper understanding of key concepts and skills. Coherent connections and consistent progressions Rigor

History of Fractions Did you know that fractions as we use them today didn't exist in Europe until the 17th century? In fact, at first, fractions weren't even thought of as numbers in their own right at all, just a way of comparing whole numbers with each other. Who first used fractions? Were they always written in the same way? How did fractions reach us here? These are the sorts of questions which we are going to answer for you. The word fraction actually comes from the Latin "fractio" which means to break. From as early as 1800 BC, the Egyptians were writing fractions. Here is an example of how the numbers were made up: Could you write down in hieroglyphics? The Egyptians wrote all their fractions using what we call unit fractions. Here is one fifth. Can you work out how to write one sixteenth? They expressed other fractions as the sum of unit fractions, but they weren't allowed to repeat a unit fraction in this addition. But this is not: was called uncia was called semis was called semuncia

cell phone project Project K-Nect is designed to create a supplemental resource for secondary at-risk students to focus on increasing their math skills through a common and popular technology – mobile smartphones. Ninth graders in several public schools in the State of North Carolina received smartphones to access supplemental math content aligned with their teachers’ lesson plans and course objectives. Students communicate and collaborate with each other and access tutors outside of the school day to help them master math skills and knowledge. The smartphones and service are free of charge to the students and their schools due to a grant provided by Qualcomm, as part of its Wireless Reach™ initiative.

Radical Math XtraMath Percentage Calculator Percentage calculator is a tool that lets you do a simple calculation: how many percent of X is Y? The tool is pretty straightforward. All you need to do is fill in two fields and the third one will be calculated for you. There are a few calculators that solve very related problems: percentage decrease and percentage increase calculators show how much things change in plus or in minus, percentage change doesn't care whether it's negative or positive and finally percentage difference takes care of a very similar concept, used when we don't know the direction of the calculation (from number A to B or B to A). What is percentage? One percent is a hundredth. It is all nice, but we usually do not use percents just by themselves. Percentage is a way to express a relation between two numbers as a fraction of 100. It's easiest to explain what is percentage on cookies. At first, let's start with 100 cookies. Let's go with something a bit harder and four times more delicious: 400 cookies!
