Algebra Meltdown Game Goals In this maths game you have been recruited by Lissaman Industries to assist in one of their super-secret, ultra-dangerous research projects. As the new controller of the mighty Nuclear Generator, your job is to serve scientists waiting at the Generator's outlets. Each scientist needs a certain atom, which you create by solving linear equations and then guiding 'raw' atoms through the Generator's maze of machines and tubes. Be quick: the scientists are impatient to continue their work. The ultimate aim of the project is to construct a monstrous mega-machine known only as 'The Device'. How To Play Algebra Meltdown's action takes place across multiple level or 'shifts', each featuring a unique Nuclear Generator layout. Across the top of the screen is a rack dispensing 'raw atoms' between values -9 and +9 (B). If an atom passes through a machine, a nuclear reaction takes place and it's transformed by the operation shown (D). Game Controls Change switch boxes by clicking on them. Add

XtraMath Radical Math 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.

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? 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: The huge disadvantage of the Egyptian system for representing fractions is that it is very difficult to do any calculations. In Ancient Rome, fractions were only written using words to describe part of the whole.

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? 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 The goal behind the demand for coherence is to make math make sense. Rigor Mathematical practices

Percentage Calculator A percentage is also a way to express the relation between two numbers as a fraction of 100. In other words, the percentage tells us how one number relates to another. If we know that number A is 25% of number B, we know that A to B is like 25 is to 100, or, after one more transformation, like 1 to 4, i.e., A is four times smaller than B. This is what the percentage calculator teaches; what is a percentage and how to find a percentage of two numbers. How to find a percentage of something? At first, let's start with the most straightforward example with 100 cookies. Let's go with something a bit harder and four times more delicious: 400 cookies! Now, something even harder - 250 cookies. So what is percentage good for? What about decimal fractions and percentages? Percentages are sometimes better at expressing various quantities than decimal fractions in chemistry or physics. A percentage is also a way to express the relation between two numbers as a fraction of 100.
