2 The Meaning of Place Value place value period decimal point power of ten The value of a digit determined by its place in a number The place value of 3 in 371,405,151 is 3 hundred million 7,205 in expanded form is (7 x 10 3 ) + (2 x 10 2 ) + (5 x 10 0 ) Key Words Vocabulary Word Definition Example Related URLs: Base Blocks, Base Blocks Decimals, handout (PDF), Power of Ten Base Blocks DecimalshandoutPower of Ten

3 Properties of Multiplication Multiplication Properties Associative Property (a x b) x c = a x (b x c) Zero Property a x 0 = 0 x a = 0 Identity Property a x 1 = 1 x a = a Distributive Property a x (b + c) = (a x b) + (a x c) Commutative Property a x b = b x a Related URLs: Multiplication Properties Rectangle Multiplication Multiplication Applet Sieve of Eratosthenes Summary of Patterns
