Common Core Standards: 5.NBT.1, NBT.2, NBT3a
I can... -recognize that each place to the left is 10 times larger in a multi-digit number (eg. 2, 20, 200). -recognize that each place to the right is 1/10 as much in a multi-digit number (eg. 2, 2/10, 2/100). -express powers of 10 using whole-number exponents (e.g. 10 = 101, 100=102, 1000=103). -illustrate and explain a pattern for how the number of zeros in a produc- when multiplying by a whole number power of 10- relates to the power of 10 (eg. 500 = 5 x 100, or 5 x 102, and has 2 zeros in its product). -illustrate and explain a pattern for how multiply or diving any decimal by a power of 10 relates to the placement of the decimal point (eg. 15.3/10 = 15.3/102; results in 0.153- decimal place in quotient is 2 places to the left of where it was in the dividend). -read and write decimals to the thousandths in word form, base-ten numerals, and expanded form.
