MULTIPLYING BY POWERS OF BASE TEN NBT. 2

LEARNING TARGET I can determine the product when a decimal is multiplied by a power of 10. Repeat after me.

OUR GOAL Complete the equations. � 9. 08 x 10= � 13 x 100= � 9. 28 x 100= � 3. 4 x 1, 000=

POWERS OF TEN Numbers like 10, 100, or 1, 000 that can be written as products of tens are called powers of ten. Multiplying or dividing by powers of ten is related to place value.

THINK ABOUT THIS…. . What do you notice is happening? Patterns can help you understand multiplying powers of ten. Thousands Hundreds Ten Ones 3 3 3 0 0 0

THINK ABOUT THIS…. What is happening when we multiply decimals by a power of ten? Ones Tenths Hundredths Thousandths 0 . 0 0 3 0 . 3 3

EVALUATE THESE PATTERNS 8 x 1=8 8 x 10=80 8 x 100=800 8 x 1, 000=8, 000 0. 009 x 1=0. 009 0. 009 x 10=0. 09 0. 009 x 100=0. 9 0. 009 x 1, 000=9 What do you notice is happening with the zeros? What appears to be happening with the placement of the decimal?

YOU WATCH ME Complete the patterns. � 0. 9 x 1= � 0. 9 x 100= � 0. 9 x 1, 000= How can I be certain that I am following the pattern correctly? Think back to “hopping”…

YOU TRY & I WILL HELP Complete the patterns. � 15 x 10= � 15 x 100= � 15 x 1, 000= Complete the patterns. � 1. 5 x 1= � 1. 5 x 100= � 1. 5 x 1, 000= How is the placement of the decimal point changing when I divide?

YOU TRY & I WILL HELP 1. ) Complete the patterns. � 37 x 10= � 37 x 100= � 37 x 1, 000= 2. ) Complete the patterns. � 0. 005 x 1= � 0. 005 x 100= � 0. 005 x 1, 000= How is the placement of the decimal point changing?

TRY A FEW THEN CHECK WITH YOUR PARTNER Complete the equation. � 432 x 100= � 0. 285 x 1, 000= � 7. 87 x 10= � 21. 9 x 1, 000=

TRY A FEW MORE THEN CHECK WITH YOUR PARTNER Complete the equation. � 60. 8 x 10= � 27 x 100= � 0. 33 x 1, 000= � 509. 4 x 1, 000=

EVALUATE MY WORK I believe that every time you multiply a number by ten you just add a zero to the end of the number. For example, 6 x 10=60. Is my claim ALWAYS true? Would it ever be false? If you agree with my claim, say, “ready to rock”. If not, drop the mic.

LEARNING TARGET Can you determine the product of a decimal when you multiply it by a power of ten? PROVE IT!!!

EXIT TICKET Complete the equations. � 9. 08 x 10= � 13 x 100= � 9. 28 x 100= � 3. 4 x 1, 000=
