5 Math Query of the Day What did the acorn say when it grew up?

6 Geometry ( Gee, I’m a tree!) CabriJr

7 You must have the arrow to drag. Press when you are pointing to what you want to drag to get a hand. Tips for CabriJr Menus are on F 1, F 2, F 3, F 4, and F 5

12 Powers of Ten Multiples of 10, multiples of. 10 to powers or exponents, to powers or exponents. Expanded form. The decimals 10., 1.,.1,.01,.001, are names for what rational numbers or fractions?

13 Top row: multiples of tens Middle row: powers of ten (just names for multiples of ten) Bottom row: decimal names for multiples of ten

Use Expanded Form to Find the Fractions

15 Expanded Form and Scientific Notation A number is in scientific notation if the number is in the form of A Problem: To change to scientific notation by first writing the number in expanded form and then in scientific notation.

16

Use expanded form and an appropriate representation of “1” to express the these numbers in scientific form

18 Division: moving the decimal point We learned that the way we do this is to “move the decimal point.”

19 How do we explain “moving the decimal point” in division?

20 How do we explain “moving the decimal point” in division?

21 So,

25 One More Division Example

26 Moving the Decimal Point: Multiplication

27 Expanded Form: Again

28 We moved the decimal point four places to the left! Wow!

29 Show and use an appropriate representation of “1” and “moving the decimal point” to express the numbers below in scientific form. Check by TI Each of the above numbers is a terminating decimal number. Express each of these numbers as a whole number and/or fraction and explain.
