math whiz™ PLAYER’S GUIDE INTRODUCTION Congratulations! You have chosen Math Whiz, the calculator and electronic game that improves math skills. Math Whiz has three modes—DRILL, CALCULATOR, and CHALLENGE. Math Whiz DRILL is a progressive sequence of problems in four skills: addition, subtraction, multiplication, and division. There are thousands of problems! Self-directed and self-motivating, Math Whiz Drill gives players the confidence to use mathematics in everyday activities.
As a CALCULATOR, Math Whiz performs arithmetic calculations for home or school. As a learning tool, Math Whiz provides hundreds of drill games, enabling players to sharpen their mental math skills from memorization to estimation to mental computation. Math Whiz CHALLENGE is a numbers elimination game that keeps players’ math minds working.
math whiz™ SPECIAL FEATURES ON/OFF Use this button to turn Math Whiz ON and OFF. MUTE Press to turn off sound. DRILL/CALCULATOR Use this button to choose a mode. SKILL Press one of these buttons to select a SKILL—ADD, SUBTRACT, MULTIPLY, or DIVIDE. NUMERAL BUTTONS Use these to input answers.
BATTERY COMPARTMENT ON BACK Requires two AAA batteries. SCREEN Greetings, selection menus, math problems, and elapsed time appear on the screen. CHALLENGE Press this button for a numbers elimination challenge. ENTER Press this button to enter answers in DRILL mode or find the answer in CALCULATOR mode. FUNCTION Press a key to add, subtract, multiply, or divide. CLR To change an answer, use the CLR button to erase the most recent number input.
HOW TO USE MATH WHIZ Math Whiz is three fully functional learning tools in one! Here’s how to use Math Whiz. Press ON to start. For DRILL 1. Press DRILL. 2. Choose one of four skills: ADD, SUBTRACT, MULTIPLY or DIVIDE. 3. Choose a LEVEL from 1 to 8. (One is easiest.) 4. After choosing SKILL and LEVEL, the screen displays EXAMPLES. 5. Press ENTER to start a game, or CLR to choose a different SKILL or LEVEL. • At levels 1 and 2, you need to select a number to drill.
For CHALLENGE The object of CHALLENGE is to eliminate numbers before the numbers eliminate you! 1. Press CHALLENGE. 2. Numbers will appear on the screen from left to right, one after another. You must eliminate numbers that add up to 10. 3. On the number pad, press the numbers adding to 10 as they appear on the screen. For example, if digits appear in this order: 2 7 8 you should press the 2 and 8 to eliminate those addends from the screen.
CONTENT BY SKILL LEVEL On the following pages, you will find a definition and examples of the kinds of problems on each level. ADD Level 1: Basic addition facts 0–9 in sequential order. Player selects number to drill, such as 4. 4+2=? 4+1=? Level 2: Basic addition facts 0–9 in non-sequential order. Player selects number to drill, such as 2. 2+4=? 2+9=? Level 3: Basic addition facts 0–9 in non-sequential order. Drill numbers are randomly mixed.
Level 6: Add three 1-digit numbers. 3+5+4=? Reminder Suggestions for mental reminders in adding three numbers: • Add the first two numbers, then add the sum to the third. • Add the easier two numbers, then add the sum to the third. Level 7: Add 2-digit numbers to 1-digit numbers or 2-digit numbers with regrouping. 28 + 9 = ? 45 + 36 = ? Level 8: Introduces the pre-algebra concept of finding the missing number (shown as ?).
SUBTRACT Level 1: Basic subtraction facts 0–9 in sequential order. Player selects number to drill. 5–2=? 6–2=? Level 2: Basic subtraction facts 0–9 in non-sequential order. Player selects number to drill. 16 – 8 = ? 13 – 8 = ? Level 3: Basic subtraction facts 0–9 in non-sequential order. Drill numbers are randomly mixed. 9–2=? 5–3=? Level 4: Subtract 1-digit numbers from 2-digit numbers without regrouping.
MULTIPLY Level 1: Basic multiplication facts 0–12 in sequential order. Player selects number to drill. 5x5=? 6x5=? Level 2: Basic multiplication facts 0–12 in non-sequential order. Player selects number to drill. 8x5=? 2x5=? Level 3: Basic multiplication facts 0–12 in non-sequential order. Drill numbers are randomly mixed and include multiplication by numbers up to 12. 5x3=? 9x2=? Level 4: Multiply 2-digit numbers by 1-digit numbers without regrouping.
DIVIDE Level 1: Basic division facts 1–12 in sequential order. Player selects number to drill. 2÷2=? 4÷2=? Level 2: Basic division facts 1–12 in non-sequential order. Player selects number to drill. 9÷3=? 15 ÷ 3 = ? Level 3: Basic division facts 1–12 in non-sequential order. Drill numbers are randomly mixed and include divisors up to 12. 12 ÷ 4 = ? 18 ÷ 2 = ? Level 4: Divide numbers ending in zero by 10 or divide numbers ending in two zeros by 100.
