We have posted several more free math lesson plans to k12math.com for 2nd Grade

2nd Grade Common Core Math

2014-07-29T13:01:00.003-07:00

The breakdown of math in the 2nd grade has been posted on k12math.com. Currently we do not have any supporting material there for consumption. It is just the article about what common core math looks like for a 2nd grader. We hope to have additional information out for teachers and parents out as soon as possible.

1st Grade Common Core

2014-07-29T12:57:00.000-07:00

There is a new breakdown of what Common Core is in the 1st Grade at k12math.com. As in a previous blog post for kindergarten, we will be posting more lesson plans, math concept breakdowns, printables, and supplementary material for teaching math. This will be targeted both for parents and teachers. The descriptions/concepts, worksheets, and printables will be for beginning educators and parents who are looking to augment students learning. The Lesson Plans are being written by two educators, one who has taught in the public school system for 30+ years, has a Masters in Education, and several IEP certifications. The second has been a programmer, adjunct professor of Computer Science, and has taught physics at the Naval Nuclear Power School in his early days. Have fun and let us know what we can improve. We basically undertaking a complete rewrite of the website using Common Core as the baseline and augmenting anything that we feel has been left out.

Kindergarten Common Core Requirements

2014-07-29T12:48:00.001-07:00

There is a new Common Core breakdown for Kindergarten at k12math.com. This article presents the standards for teachers, parents, but is too detailed for actual kindergarten students. There will be additional kindergarten lesson plans posted...some free and, when the site has several hundred available, some for a minor fee. Current thinking is that the fee will be about $10 per year to help with hosting costs and to provide money for scholarships. This is due to change but hopefully you will find it helpful.
Sincerely,

Functions

2007-06-18T05:16:00.000-07:00

There are times when various quantities can be related to one another. If this relationship follows a regular pattern then we can assign variables to these quantities and write a mathematical equation to express this relationship. This relationship is called a function. More on functions...

Scientific Notation Practice

2007-04-24T08:36:00.000-07:00

Scientific Notation (exponential notation) refers to writing decimal numbers as a number multiplied by a power of 10. Now this is done in a certain way. What this boils down to is moving a decimal point, keeping track of how many places you moved it, and increasing or decreasing the power of 10 by that number of decimal...(cont. Scientific Notation Practice)

Equations of the Line

2007-04-19T07:27:00.000-07:00

Linear equations have variables whose highest power is 1. Also the variables are not multiplied together. We say there is a linear relationship between the variables in these equations. This linear relationship implies that as one variable changes the other changes with a constant rate of change....(cont. Linear Equations)

Exploring Inequalities

2007-04-19T07:22:00.000-07:00

An inequality is a special equation that describes how two expressions are not equal. The signs <, ≤, ≠, >, and ≥ are used to express inequalities...(cont. Inequalities article)

Quadratic Equations Tutorial

2007-03-30T06:57:00.000-07:00

A quadratic function is an equation where the exponents of the variables are not greater than 2 but at least one variable with an exponent of 2, and if the variables are multiplied, not greater than 2. ...quadratic equations free lesson plan

I posted a new free math lesson plan to K12math.com on quadratic equations. Please feel free to download it and use it for your students or in your classroom.

Real Numbers Tutorial

2007-03-26T17:49:00.000-07:00

The Real numbers include the integers, the rational, and the irrational numbers and are represented as points on the number line. Every real number has its own position on this number line, and this one to one correspondence with no gaps makes these numbers a continuum. ...for a free math lesson plan on real numbers

Simplifying Expressions

2007-03-05T17:54:00.000-08:00

Simplifying Expressions
Simplifying expressions is a skill that requires a significant amount of practice. Prerequisite is a clear and thorough understanding of the properties of integers which apply to the real numbers as well. These properties may seem obvious; when applied to variables, somehow they lose their opacity. These laws should be reviewed and reinforced as they are used (with numerical examples as examples) to simplify algebraic expressions. Variables and constants represent real numbers and therefore abide by these laws. ...full article by Russ Lewis
