5. A number that represents a part of a whole or a group; also means 'divided by' - E.g. 1/2 -3/4.5/6






6. New whole






7. Choosing numbers close to the numbers in a problem - and then adjusting the answer to compensate for the numbers chosen - E.g. 23 + 18 and 23+20=43 Since 2 was added to 18 to make 20 - we need to take 2 away from 43.






8. To find a number that is close to an exact answer - E.g. 23+24 is around 50

13. A property of real numbers that states that the sum or product of a set of numbers is the same - regardless of how the numbers are grouped - (a+b)+c=a+(b+c) - e.g. (1+2)+3=1+(2+3)






14. The number at the top of a fraction; stands for the parts of a set you are considering - E.g. 3/4 What position is 3?






15. In 4x4=16 - what is 4?






16. Any whole number that ends with 0 - 2 - 4 - 6 - or 8 - any whole number that can be divided by 2

38. The bottom number in a fraction; tells how many parts a whole is divided into OR how many parts in a group - E.g. 2/4 and what position is the 4?
