Today we looked at place value with decimal numbers into the millionths. A lot of the concepts are very similar to place value with large numbers, except now are looking at numbers on the right side of the decimal comma. The most important part is to understand the vocabulary in French for each place value and what each word means.
You can reinforce with your child that 1 digit after the decimal comma is the tenths (dixiemes) place, 2 digits after the decimal is the hundredths (centiemes) place, 3 digits after the decimal is the thousandths (milliemes) place, 4 digits after the decimal is the ten thousandths (dix-milliemes) place, 5 digits after the decimal is the hundred thousandths (cent-milliemes) place, and lastly 6 digits after the decimal is the millionths (millioniemes) place.
1. Represent each number in a table of place values (I showed everyone in class what to do for this question).
2. Using the numbers in the yellow box, match each number with the letter for the correct place value of the 5 digit. In other words, for a), which of the numbers in the yellow box has the 5 in the ten thousandths place (dix-milliemes)? Then do the same for b), c), d), e).
a) ten thousandths (dix-milliemes)
b) millionths (millioniemes)
c) thousandths (milliemes)
d) hundred thousandths (cent-milliemes)
e) tenths (dixiemes)
3. What is the place value of each digit in the number 4, 524371?
4. Write each number in standard form (forme symbolique).
ex. 3, 9586
5. Write each number in expanded form (forme developpee).
ex. 3 + 0,9 + 0,05 + 0,008 + 0,0006 = 3, 9586
