Step 1Copy the complete problem.
Leave a small space between the number and the unit.Example:
25 L = ____________ mL
![Page 4: For each of the following commonly used measurements, indicate its symbol. Use the symbols to complete the following sentences with the most appropriate](https://reader035.vdocuments.mx/reader035/viewer/2022081511/56649d8b5503460f94a71cb1/html5/thumbnails/4.jpg)
Step 2If there is no decimal point, add one at the end of the
number.Think about how you would add a period at the end of a
sentence.Our Example:
25 L = __________ mL
If there is a decimal point, start from there.

Step 3Decide, will you be going from a larger unit to a
smaller unit?This means you will be going DOWN the staircase.So you will be moving the decimal point to the RIGHT.
Or, will you be going from a smaller unit to a larger unit?This means you w ill be going UP the staircase. So you will be moving the decimal point to the LEFT.Our Example:
L to mL, which way are we going?
Bigger DOWN to smaller.
![Page 6: For each of the following commonly used measurements, indicate its symbol. Use the symbols to complete the following sentences with the most appropriate](https://reader035.vdocuments.mx/reader035/viewer/2022081511/56649d8b5503460f94a71cb1/html5/thumbnails/6.jpg)
Step 4After you decide which way the decimal point moves,
draw a small arrow in that direction just above the number to help you remember which way you are going to move the decimal point.
Our Example: 25. L = __________ mL
![Page 7: For each of the following commonly used measurements, indicate its symbol. Use the symbols to complete the following sentences with the most appropriate](https://reader035.vdocuments.mx/reader035/viewer/2022081511/56649d8b5503460f94a71cb1/html5/thumbnails/7.jpg)
Step 5Next, look at the SI staircase and decide how many
steps you need to move from the given to the unknown units.
Our example: L to mL① From liter to deci② From deci to centi, ③ From centi to milli

⏎⏎
• We moved down 3 steps so the decimal point will move three places to the right.

Step 6Next, draw in each arrow, one at a time.
Add zero’s to hold place as needed.Our example: 25 L = ___________ mL
Finally, rewrite the new answer in the blank, including zeros and the new placement of the decimal point.
25. L = 25000. mL
Final placement of the decimal point.

Let’s do another example
![Page 10: For each of the following commonly used measurements, indicate its symbol. Use the symbols to complete the following sentences with the most appropriate](https://reader035.vdocuments.mx/reader035/viewer/2022081511/56649d8b5503460f94a71cb1/html5/thumbnails/10.jpg)
Step 1Copy the complete problem.
Leave a small space between the number and the unit.Example:
64.7 cm = ____________ km
![Page 11: For each of the following commonly used measurements, indicate its symbol. Use the symbols to complete the following sentences with the most appropriate](https://reader035.vdocuments.mx/reader035/viewer/2022081511/56649d8b5503460f94a71cb1/html5/thumbnails/11.jpg)
Step 2If there is no decimal point, add one at the end of the
number.
If there is a decimal point, start from there.Our Example:
64.7 cm = ____________ km
There is already a decimal point in our example.
![Page 12: For each of the following commonly used measurements, indicate its symbol. Use the symbols to complete the following sentences with the most appropriate](https://reader035.vdocuments.mx/reader035/viewer/2022081511/56649d8b5503460f94a71cb1/html5/thumbnails/12.jpg)
Step 3Decide which direction you are going to move?
Our Example: cm to kmSo we are going from a _________ unit to a _______ unit.
This means we are going ________ the staircase.
So we will be moving the decimal point to the _______.
smaller bigger

Step 4After you decide which way the decimal point moves,
draw a small arrow in that direction just above the number to help you remember which way you are going to move the decimal point.
Our Example: 64.7 cm = ____________ km

Step 5Next, count how many steps we need to move up the
staircase, from centi to kilo.① From centi to deci② From deci to meter, ③ From meter to deka④ From deka to hecto⑤ From hecto to kilo ⏎

• We moved up 5 steps so the decimal point will move five places to the left.

Step 6Draw arrows that swoop to the left , 5 times.
Our example: 6 4 7 cm = ___________ km
Finally, rewrite the new answer in the blank, including zeros and the new placement of the decimal point.
64.7 cm =
Final placement of the decimal point.
