Master the Graphing Calculator

The most important math tool for success in high school is the TI 83 or 84. The better you are at using these, the faster you solve your problems and the less mistakes you will make. You have got to be an expert at using these and understanding what all those buttons can do for you.

These videos can help you through much of the confusion.

Mathbits is a great site to get answers to all your graphing calculator issues.

Regents Solutions on YouTube

Check out some great videos of past math regents problems being solved with all the steps. It also shows how to correctly set your graphing calculator, which will save you time. As the regents gets closer (see side link for your regents schedule), this is a great way to do some extra studying and review.

Ken You Solve it?

KenKen is a great Japanese math game similar to Sudoku that is supposed to train your brain to do simple math quickly.

The rules are simple:

As in sudoku, the goal of each puzzle is to fill a grid with digits - 1 through 4 for a 4×4 grid, 1 through 5 for a 5×5, etc. - so that no digit appears more than once in any row or column. Grids range in size from 3×3 to 9×9. Additionally, KenKen grids are divided into heavily outlined groups of cells - often called “cages” - and the numbers in the cells of each cage must produce a certain “target” number when combined using a specified mathematical operation (either addition, subtraction, multiplication or division). For example, a three-cell cage specifying addition and a target number of 6 in a 4×4 puzzle might be satisfied with the digits 1, 2, and 3. Digits may be repeated within a cage, as long as they are not in the same row or column. No operation is relevant for a single-cell cage: placing the "target" in the cell is the only possibility. The target number and operation appear in the upper left-hand corner of the cage.

Try it here, and keep coming back for new puzzles every day.
