A different way to look at Mathematics
Do we all remember what the place value system is?
A number will always have at least on of these places filled in.
Practice figuring out numbers place values.
200 + 40 + 3 + 0.7 +.06 = 243.76
10,000 + 3,000 + 800 + 10 +7 + 0.7 + 0.02 + 0.003 = 13817.723
The Egyptians used the place value system as well!
Instead of saying thousands, hundreds, and tenths, they used symbols.
The next slides explain what symbols represent what place values!
A hobble is a device around the legs of cattle to handicap but not completely prevent movement.
The thousands place is represented by a drawing of a lotus plant. This picture is of 1 thousand.
Who’s finger do you think they would model for their number place system?
Frogs were all over the ancient River Valley Civilizations.
The millionths place in the place value system is represented by a figure of a god with its arms raised above its head. This is a picture of 1 million.
What God or God’s were followed during this time period? Who would the Egyptians choose to represent the millionth place in their number system?
This is the Ones place value
This is the Tens place value
30 + 6 = 36
5 ten thousands
50,000 +1000 +600 +10 +4 = 51,614
