QUESTIONS AND ANSWERS
NUMBERS
ADDITION:
● A way of putting together 2 or more things to find out how-many there are together.
● Each addition fact-is made up of 2 or more addends and a sum
● Some beginners practise with coins or bottle caps
● Each addition fact-consists of-an (ADDEND) + (ADDEND) = (SUM)
BASIC FACTS
COUNTING TOGETHER When you put-together 2 or more sets to form a new set-
and find out how many there are together in the new set,
you can count them together.
THINKING TOGETHER Is a quicker way of adding than counting together.
Example:
4 + 5 = ???
(4+4= 8 ) so (4+5 will be 1 more)
therefore 4 + 5 = 9
REGROUPING Changing the sets to the nearest 10 is called
regrouping EXAMPLE: 9 + 6 +15 OR (9 +1 =10)

SUBTRACTION
● A way of taking away a number of things from a larger number of things
● A number is taken away to find out how many things are left
● Each subtraction fact consists of a MINUEND, a SUBTRAHEND and a REMAINDER
or DIFFERENCE.
BASIC FACTS
DICE-AND-DRILLING-ACTIVITIES
➔ use one/two more than dice
➔ 1 : labelled with +1, +2
➔ 2 : labelled 4, 5, 6 ,7, 8, 9
➔ After each roll of the dice, children should say the complete fact: four and two is six

● Drill is good for strengthening memory and retrieval capabilities.
● Dice can be used to to complete the facts of-numbers for example if you get’ 3 and 6 its 9’
● They can use it to add doubles doubling the number-that they get.
● They can use a dice with numerals or the one with just number symbols.
