Division Vocabulary Review

Division Quotient – the answer to a division problem. Dividend – the number being divided. Divisor – the number doing the dividing.

to help you make good estimates. Compatible Numbers Numbers that are easy to compute mentally. Example of using compatible numbers in division: 310 ÷ 8 Adjust 310 to 320 because 32 ÷ 8 = 4. 320 ÷ 8 = 40. Use basic math facts to help you make good estimates.

Remainder The part that is left over after completing a division problem. The remainder should NEVER be the same or larger than the divisor!

Divisible A number is divisible by another number if when it is divided there is no remainder. Examples: 35 ÷ 7 = 5. 35 is divisible by 7 because there is no remainder. 24 ÷ 8 = 3. 24 is divisible by 8 because there is no remainder.

Mean Mean – A fancy word for the average. The average of a set of data is found by adding all the numbers together and dividing by the total of numbers in the data. Example: 3, 5, 3, 5, 4 – these numbers added together equal 20. The next step is to count the numbers in the data. There are 5 numbers. Then divide – 20 ÷ 5 = 4. The mean (average) is 4!
