Lesson 1: Intro to decimals

Writing decimal numbers shown in grids

Sal uses grid diagrams to determine what decimal is represented by a shaded area.

• How do you expand form 9.06?
• 4.03-4+0.03 that is expanded form study it
• I thought that in the decimal places, the ones were the first numbers to the left...
• They are. Here is a place value chart:
`Millions`
`Hundred Thousands`
`Ten Thousands`
`Thousands`
`Hundreds`
`Tens`
`Ones`
. DECIMAL POINT
`Tenths`
`Hundredths`
`Thousandths`
`Ten Thousandths`
`Hundred Thousandths`
`Millionths`
• can you simplify decimals
• Technically, yes, but it's really easy. If you've got a number like 12.456000 (with no numbers after the zeroes) you could simplify it to 12.456. Or 2.0 could be simplified to 2. But that's really all you can do to simplify a decimal.
• can there be a septoseptillian grid?
• bring your self up not down
• what happens if there is one hole and one shade on the other
• Why didn't you wright 3.05? And you wrote 3.5
• in https://www.khanacademy.org/math/arithmetic/arith-decimals/arith-review-decimals-intro/e/decimal-intuition-with-grids on the first question, do you write 0.1,0.10,0.100,0.1000,0.10000,or 0.100000?
• You can write 2.03 for the decimal part as there is 2 wholes and 3 hundredths. For the fraction part you can write 2 3/100. Remember to put the space in between the whole number and the fraction as it is a mixed number.
• when it tells you to write 3 hundreths in decimals do you write it like this? 0.03?

• take a snack brake you have been working to hard
• how do you write the shades area as a fraction

• count how many wholes (fully shade) then that is the whole number then count how many equal lines are there and how many are shaded the number on top (numerator) is the shaded and the number on the bottom (denominator) are the number of how many equal lines

FOR EXAMPLE (if there are no whole numbers):

there are 3 equal line and there are 2 equally shaded lines so that means the 2 shaded lines are the numerator and the 3 equal lines as the denominator
