Guide for Teachers and Parents
Congratulations! You have chosen MathShark, the calculator and electronic game that improves math skills.
As a CALCULATOR, MathShark performs arithmetic calculations for home or school. As a LEARNING tool, MathShark provides hundreds of drill games, enabling students to sharpen their mental math skills— math performed mentally rather than on paper—from memorization to estimation to mental computation.
MathShark LEARNING is a progressive sequence of problems in seven skills: addition, subtraction, multiplication, division, decimals, fractions, and percents. There are thousands of problems! Selfdirected and self-motivating, MathShark gives players the confidence to use mathematics in everyday activities.
MathShark users of all ages and skill levels find that these features help them sharpen math skills at their own individual pace:
Repeated drill Each SKILL has eight sequential levels. At each level, there are ten or more game sets—ten problems per game. At the end of each game, the player can choose to replay that game to improve timing, go to the next game on that level, or change to another level or another skill.
Immediate feedback Different tones and lights tell the player whether the answer is correct or incorrect. Incorrect answers are immediately corrected on the screen.
No-fail game format Incorrect answers are recycled into the game and repeated. Game play continues until all problems are answered correctly.
Self-assessment At the end of each game, a player’s elapsed time is shown on the screen. The player can try to improve that time by repeating the game.

Why is MathShark an Important Learning Tool?
Mathematics skills are useful throughout our lives. Teaching strategies may change, yet most educators agree that acquiring mathematics skills means learning to:
• apply math skills outside the classroom
• develop problem-solving techniques
• inquire, analyze, and reason mathematically
• communicate mathematically
MathShark’s fast, continuous drill games and instant feedback give students the basic tools they need to reason and problem-solve accurately and effectively—inside and outside the classroom.
SUGGESTIONS FOR USE
MathShark can be useful in many ways. Some suggestions for incorporating
MathShark in the home or classroom are listed below:
In the Home
• Have children spend 15-30 minutes on MathShark drill games as part of their homework schedule. The ASSESSMENT chart on pages 10 -11 can help parents and children keep track of skills review or mastery.
• Make MathShark a traveling companion—MathShark can fit in a backpack and travel by car, train, bus, or plane.
• Encourage players to keep track of their scores (on the ASSESSMENT chart or another piece of paper) and try to improve their times.
• Challenge family members to a friendly MathShark competition. Players choose a SKILL and a LEVEL and see who gets the best time.
• Substitute MathShark for TV and see what happens!
In the Classroom
• Use MathShark as an individual skill builder. Five or ten minutes with
MathShark turns “free time” into a productive learning experience.
• Make MathShark a permanent feature in any Math Learning Center.
• Use MathShark for cooperative learning. Pair students and have them take turns drilling basic math facts or specific skills and keeping a record of their times.
• Use the MathShark ASSESSMENT chart on pages 10 -11 to track students’ progress.
• Encourage students to track their own progress by comparing their times for the first game they play at each level with games played after using the drills practice.

HELP
Help offers tips, steps, or alternate ways to look at a problem. Visualization is an important part of mental math.
When applicable, MathShark gives learners two ways to look at a problem.
The HELP button can also be used to adjust the display CONTRAST on your screen. Turn MathShark on, and press
HELP during the opening screen. Use the + and – buttons to adjust contrast for maximum visibility. Press ENTER to return to the main menu.
HOW TO USE MATHSHARK
MathShark is two fully functional learning tools in one! Press ON to start
MathShark. It will come on in LEARNING mode unless you press
CALCULATOR.
For CALCULATOR
1. Press CALCULATOR.
2. Input the first number.
3. Press a function key (
+ x
÷
).
4. Input the next number.
5. Press ENTER and the answer will show.
6. Continue the process for a multiple step problem.
7. Press CALCULATOR or CLR to begin a new problem.
For LEARNING
1. Press LEARNING if you are in CALCULATOR mode.
2. Select SOUNDS ON or OFF. To silence MathShark’s tones, press CLR at this menu. To hear them, press ENTER and proceed.
3. Choose one of seven skills: ADD, SUBTRACT, MULTIPLY, DIVIDE,
FRACTIONS, DECIMALS, PERCENTS.
4. Choose a LEVEL from 1 to 8.
ADD, SUBTRACT, MULTIPLY, and DIVIDE begin by drilling basic facts:
Level 1—drills facts for a specific number in sequential order, for example: 1 + 1, 2 + 1, 3 + 1
Level 2—drills facts for a specific number in random order, for example: 4 + 2, 8 + 2, 3 + 2
At Level 1 or Level 2, player chooses NUMBER TO DRILL.
For example: To drill basic multiplication facts for 6, choose
MULTIPLY, LEVEL 1, DRILL NUMBER 6.
Level 3—mixes the number facts drilled in random order, for example: 5 + 1, 6 + 4, 2 + 9
Levels 4–8—provide programmed math problems in a skill area in progressive sequence. (See examples in Content by Skill Levels.)
ADD, SUBTRACT, MULTIPLY on Level 8, and DIVIDE on Levels 7 and 8—introduce pre-algebra skills by having players find the missing number in a math problem.
DECIMALS, FRACTIONS, and PERCENTS on Levels 1–8 —provide skills practice in increasing difficulty.
6
5. After choosing SKILL and LEVEL, screen displays EXAMPLES.
6. Press ENTER to start a game, or CLR to choose a different SKILL or
LEVEL.
7. First problem appears. Input an answer, then press ENTER. To enter a
.
fraction, use the A/B button. To enter a decimal, use the button.
The HELP button offers a visual clue. The HELP screen might display the problem in another way or provide a hint to getting the correct answer. After using the HELP screen, press HELP again (or CLR or
ENTER) to return to the problem screen and ENTER an answer.
8. If the answer is correct, the green light flashes and the correct answer tone plays.
9. If the answer is incorrect, the red light flashes and the incorrect answer beep plays. The correct answer flashes and the problem recycles into the game. Play continues until all 10 problems are answered correctly
(even if it takes 50 tries!).
10. At the end of each game, the screen displays a congratulatory message and the elapsed time.
11. Make one of these selections:
• advance to the NEXT game, press
+
.*
• repeat the SAME game, press ENTER.
• CHANGE skills by returning to the main menu, press CLR. To change levels, press CLR, choose a SKILL, then choose a LEVEL.
(To change SKILL during a game, press LEARNING to return to the main menu.)
* In ADD, SUBTRACT, MULTIPLY, and DIVIDE on Levels 1 and 2, MathShark will advance to the next LEVEL after the highest drill number is completed. All other levels and skills will repeat continuously until CLR is chosen from the end-of-game menu.
To conserve batteries, MathShark is set to “go to sleep” after 300 seconds, or five minutes. Pressing any button will “wake up” MathShark.
When player completes a game after waking up MathShark, the elapsed time at the end will say 300 SECS, the maximum time.

MathShark Content by Skill Levels
The MathShark Skills Scope and Sequence Chart on pages 20 –21 gives an overall look at content in each skill and on each level.
The following pages provide a definition of the content for each skill and level, plus some example problems. You may want to use the examples to
introduce a new or difficult concept. You might also want to make a reproducible sheet of problems for practice or for assessment.
For teacher assessment, use the reproducible ASSESSMENT chart on pages
10–11 to keep track of each player’s mastery. Students or parents can use the chart to keep track of individual achievements.
