Question | Answer |
• Whole numbers | – The numbers 0,1,2,3,4,5, etc. |
• Integers | – All positive and negative whole numbers (including zero). That is, the set {... , –3, –2, –1, 0, 1, 2, 3, ...}. Integers are indicated by either Z or J. |
• Fractions | – parts of groups, numbers, or wholes |
• Skip Counting | – Counting forwards or backwards in multiples or intervals of a given number. |
• Rote Counting | – learning to count without practicing with pen and paper but by making the child speak the counting again and again, without help of any book. |
• Numeration | 1 a: the act or process or an instance of counting or numbering ; also : a system of counting or numbering b: an act or instance of designating by a number2: the art of reading in words numbers expressed by numerals. |
• Distributive Property | – Multiplying a number is the same as multiplying its addends by the number then adding the products. Also a product can be written as, the sum of, or difference between, two products. a(b+c) = ab + ac. |
• Commutative Property | – In addition and multiplication, numbers may be added or multiplied together in any order. a + b= b + a, a*b=b*a, ab=ba |
• Associative Property | – In addition and multiplication, no matter how the numbers are grouped, the answer will always be the same. (a +b) + c = a + (b + c), (a*b) *c = a * (b * c) |
• Identity Property of Addition | – adding zero won’t change a number or when zero is added to a number the result is the number itself, also known as the identity property of zero |
• Identity Property of Multiplication | – multiplying by 1 won’t change a number, when a number is multiplied by 1 the result is itself, also known as the identity property of one |
• Algorithim | – a way of setting out a step by step mathematical procedure. A method used to find an answer. |
