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? 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. was called uncia
Addition in Columns You can do addition by writing one number below the other and then add one column at a time, like this: (Practice on this Simple Column Addition Worksheets) And it works for bigger numbers, too: But sometimes two-digit numbers can get in the way like this: THIS is how it should be done: Here's another example (done a little faster): Now practice on this Column Addition (with Carrying) Worksheets The same method works with numbers in the hundreds, thousands and so on. Like this:
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.

Problems of the Month Problem solving is the cornerstone of doing mathematics. A problem that you can’t solve in less than a day is usually a problem that is similar to one that you have solved before. But in real life, a problem is a situation that confronts you and you don’t have an idea of where to even start. If we want our students to be problem solvers and mathematically powerful, we must model perseverance and challenge students with non-routine problems. Administrators, teachers and parents should facilitate and support students in the process of attacking and reasoning about the problems. The solution is not as important as the process of problem solving. The educator or parent should not be impatient with the student’s struggle. The principal should embrace the concept of problem solving and model problem-solving leadership, being a facilitator of non-routine problems. Once the problem is presented to the students, the principal should be visible in facilitating the tasks alongside the teachers.

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? 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
