100's number chart Interactive number chart that can be used in many ways:
1. Offline Worksheet-Click on the printer icon located in the interactive game (where it says "Full Page Print") to print out an uncolored number chart worksheet.

2. Skip Counting Have students color the number chart to reinforce different lessons. For example, have them select a color and color all the squares that are multiples of two the same color. Repeat for number patterns for counting by fives and tens by selecting a different color. The chart becomes a great visual for skip counting by 2's, 5's, and 10's.

3. Multiplication Tables Have students color code the number chart for math factors and multiplication tables. You may print a different chart out for each number set, or work off of one chart. For example, color all multiples of three the same color. Do students see a pattern? Then color all multiples of four a different color from multiples of three.

Algebasics This website is well organized, and is a great resource for kids who cannot remember which rules to apply. It covers inequalities, polynomials, exponants, factoring, ratios, linear equations and more. Each example is illustrated and narrated. 

Check Writing, Checkbooks, Checking account  This site will let you print blank checks, print a check register, and show kids how to balance a checkbook. There is an interactive activity for filling in a check register.

Clock Wise-This is an  online activity for telling time. You can tell it what time to display, or have it quiz you. Levels 1-3 for difficulty.

Free Graph paper online-This site has lots of pre-made grid formats.

GraphCalc -Online graphing calculator--sorry, Windows only.

Graph Paper -Make your own graph paper and print it out-you can specify the size of the boxes, color of the lines and pattern of the grid. Download as a pdf file and print.

Johnnie's Math Page has interactive games and activities for teaching fractions, geometry, probability, measurement, multiplication and statistics.  There is an emphasis on digital manipulatives, and you will find math lessons and math worksheets as well as links to other math teaching resources.  For those who like a challenge, you will find free math games in the math puzzles section.

Khan Academy What started out as Sal making a few algebra videos for his cousins has grown to over 2,100 videos and 100 self-paced exercises and assessments covering everything from arithmetic to physics, finance, and history.

Learn With Math Games (Thanks to Dawn Miller) Math activites are sorted by grade level and by skill. Some are on-line games, some are printable. There are even games that kids can make themselves. If you have a good idea for a math game, you can submit your game to have it included.

Manipulatives This site gives you tons of options for manipulatives --you can pick the grade level, what kind of background you want (number lines, story boards, gameboards) and manipulatives (money, bears, two-color counters) and then gives you a ton of tools, including a timer, protractor, ruler and stopwatch. You can draw, type and interact with all the tools, then print out your project. Very cool!

Sokikom (so-kee-kom) motivates elementary students in an exciting, safe math social learning game. Our research-tested approach uniquely connects massively multiplayer online game play with NCTM focal points and Common Core State Standards. The result? Intensely engaged kids. And higher math achievement. Teachers log into an account, and set up access for their students. Each student's progress is monitored, and the teacher gets a report of what they have done.

ThinkingBlocks   --a suite of learning tools designed to help students solve math word problems accurately and efficiently. Using brightly colored blocks, students model mathematical relationships and identify known and unknown quantities. The model provides students with a powerful image that organizes information and simplifies the problem solving process. By modeling increasingly complex word problems, students develop strong reasoning skills which will facilitate the transition from arithmetic to algebra.
