PLACE VALUE FROM MILLIONS TO THOUSANDTHS UNIT 1 ? WHAT DO YOU NOTICE ABOUT THE DIFFEFENCE OF EACH PLACE VALUE? This is what is called the Power of Ten! LET’S LOOK AT PLACE VALUE WHEN EACH DIGIT IN THE NUMBER IS THE SAME 3,333.333 This 3 is in the ones place. It has a value of 3. LET’S LOOK AT PLACE VALUE WHEN EACH DIGIT IN THE NUMBER IS THE SAME 3,333.333 This 3 is in the tens place. It has a value of 30. LET’S LOOK AT PLACE VALUE WHEN EACH DIGIT IN THE NUMBER IS THE SAME 3,333.333 This 3 is in the hundreds place. It has a value of 300. LET’S LOOK AT PLACE VALUE WHEN EACH DIGIT IN THE NUMBER IS THE SAME 3,333.333 This 3 is in the thousands place. It has a value of 3000. Now let’s look to the right of the decimal. LET’S LOOK AT PLACE VALUE WHEN EACH DIGIT IN THE NUMBER IS THE SAME 3,333.333 This 3 is in the tenths place. It has a value of 1 10 of the 3 in the ones place. LET’S LOOK AT PLACE VALUE WHEN EACH DIGIT IN THE NUMBER IS THE SAME 3,333.333 This 3 is in the hundredths place. It has a value 1 of 100 of the 3 in the ones place. LET’S LOOK AT PLACE VALUE WHEN EACH DIGIT IN THE NUMBER IS THE SAME 3,333.333 This 3 is in the thousandths place. It has a value 1 of 1000 of the 3 in the ones place. PRACTICE 1: 25 x 103 = 25 x (10 x 10 x 10) = 25 x 1000 25.000 = 25,000 PRACTICE 2: 32 x 105 = 32 x (10 x 10 x 10 x 10 x 10) = 32 x 100,000 32.00000 = 3,200,000 PRACTICE 3: 46 x 106 = 46 x (10 x 10 x 10 x 10 x 10 x 10) = 46. x 1,000,000 46.000000 = 46,000,000 PRACTICE 4: 3.5 x 104 = 3.5 x (10 x 10 x 10 x 10) = 3.5 x 10,000 3.5000 = 35,000 PRACTICE 5: 5.1 x 102 = 5.1 x (10 x 10) = 5.1 x 100 5.10 = 510 PRACTICE 6: 6.73 x 105 = 6.73 x (10 x 10 x10 x 10 x 10) = 6.73 x 100,000 6.73000 = 673,000 ? The exponent above the ten indicates how many places the decimal point is moving to the right because you are multiplying making the number 10 times greater when you multiply by the power of ten. INDEPENDENT PRACTICE (INTERACTIVE NOTEBOOK) 1. 3 x 106 = 2. 12 x 102 = 3. 72 x 109 = 4. 8.6 x 104 = 5. 7.5 x 105 =
