Practice makes perfect, and that's why math worksheets are an educational staple in the classroom and at home. Today's collection of math worksheets for grades one through nine, focuses on the print-it-out-and-work-on-it-with-a-pencil variety, but some of these sites also offer interactive worksheets for online use.
Aplusmath offers both interactive and printable worksheets customizable by operator and range of operands. Unique offerings include Counting Money (complete with color graphics), Basic Algebra, and my personal favorite, a PDF Worksheet Generator. The problem with most customized worksheets is printing them from your browser, because browser windows do not format neatly into 8.5" x 11" pages, and come with all sorts of unnecessary headers and footers. All these problems are solved with the PDF Worksheet Generator. Look for it in the bottom left-hand corner.
The Math Goodies worksheets are organized by grade-level. For grades four through nine, there are ten pre-made printable worksheets that correspond to their thirty-eight free math lessons in topics such as Pre-Algebra, Geometry and Statistics. For grades one through four, enter the Math Fact Cafe, where you'll find customizable printable worksheets, and off-the-shelf worksheets, both printable (click on any question icon) and interactive (look for the pencil icon.) Don't miss the interactive flash cards (basic addition, subtraction, multiplication and division drills) also found in the Math Fact Cafe.
The Math Worksheet Site, a tool for creating an unlimited number of customized printable math-related worksheets and answer keys, is a labor of love for homeschooling dad Scott Bryce. In addition to the usual operators, the site includes fractions, graphing, telling time, reading a tape measure, and a one hundred chart. "A one hundred chart has a variety of uses. A one hundred chart can be used to teach counting or skip counting. A one hundred chart that starts at zero is good for introducing the concept of place value. A one hundred chart that starts at one can be used to teach about the Sieve of Eratosthenes, and for finding prime numbers."
SuperKids customizable printable worksheets cover the basics (addition, subtraction, multiplication, and division) plus rounding, fractions and greater than/less than. To create both a worksheet and answer key, first generate and print the worksheet, and then click on the Create Answer Sheet button at the bottom of your worksheet. If you attempt this in reverse order, your answer key won't match your worksheet.
Although they are not customizable, Teach-nology has a huge assortment of pre-made worksheets covering a wide variety of math topics. Unique categories include Do Now! warm-up exercises for grades one through eight, magic numbers, stock market, tic-tac-toe math, estimation, surveys and word problems. Before printing any of the worksheets, be sure to select Printable Version from the top horizontal menu. This will display a version sans the top and bottom banner ads. Scores of non-math worksheets can be found by clicking around the Worksheet Categories menu.
