Subject: Decimals, even numbers, fractions, and order

I have a few questions actually. How would you explain to children the following: *Even numbers always end in 2, 4, 6, 8, and 0. *You can decide which of two fractions is greater by finding equivalent fractions with the same numerator and comparing them. *You can stick zeroes at the end of a decimal amount and not change its value, ex, 3.45 = 3.45000000. *You can add the same amount to both numbers when your subtracting them and not change the answer. *You can halve one number and double another when you multiply and not change the answer.
