Interesting Facts about Numbers
It is important that teachers know some facts about numbers so that they can make their number lessons more
interesting. Give each group a number to discuss from 1 to 9. Let each group make a list of all the patterns and
interesting associations for each of the numbers. Here are a few of the possibilities which include facts more
suitable for older pupils:
I (One): one nose, mouth, etc. Goat, cow and sheep has one tail. Not prime. Does not alter any other number
that it multiplies. Greeks thought it was odd and even (wrongly).
One tail; one lonely tree:
2 (Two): two eyes, ears, arms, legs, feet, etc. Pairs. Couples. Birds have two legs. Bi (2) in biannual, bible,
bicentenary, biceps, bicolour, bicuspid, bicycle, bifocal, bigamy, bikini, bilateral, bilingual, billion, binary, binocular,
biology, biped, biplane, bisect, bivalve. Greeks saw as a number with "beginning" and "ending" but no "middle".
Unique in that 2 + 2 = 2 x 2. First prime number and only even prime number.
Two wheels; two eyes; two legs; two lenses:
3 (Three): Triangles. Tri (3) in triangles, triad, triceps, tricolour, tricycle, trident, triennial, trigonometry, trig point,
trilogy, trinity, trio, triple jump, triplets, triplicate, tripod. First odd prime number.
Three wheels; three sides; three legs; three sides to the triangle:
4 (Four): Squares. Four legs on chairs, tables, mammals. Cubes have square faces.
Quad (4) in square, quadrangle, quadrant, quadrilateral, quadruped, quadruple, quadruplet, quadruplicate. Four
cardinal points of the compass.
Four legs; four points; four legs:
5 (Five): Hand (fingers); foot (toes). Petals. Points on a star. Pentagon.
Five fingers; five toes:

Children’s activities for early number
Special note: the singular version of dice is die, but as most pupils and teachers refer to a die as a dice, we will
use this term throughout the book.
1. Game: Find the partner
You need: Cards with numerals, and cards with dots, stars, animals shapes (See the Printable Materials
section)

Children practise matching up the two corresponding cards:
7
1
5
3
6
2
2. Game: Numbers Race
You need: A large dice with dots on each face, from 1 to 6. A play court scratched in the earth outside the
classroom (this can be marked with chalk inside the classroom if preferred):
6
1
4
2
5
3
5
2
6
3
4
1
1. Two teams (of about 6) line up on each side of the number court.
2. Each pupil takes it in turn to throw the dice. When a number is thrown, the child stands on that number written
in the square.
3. The teams continue to throw the dice, in turn, until one team covers all the numbers on their side of the court
and become the winners.
4. This game can be played on paper on the desk, and a stone is placed on the paper when a number is thrown.
3. Game: Snake’s Eye
You need: A Snake's Eye drawing (See the Printable Materials section). A die, with numerals 1 to 6 on
each face. A small stone for each pupil.
1. Up to 6 pupils can play in one group.
2. Each pupil throws the dice in turn, in a clockwise direction.
3. From the START pupils look for the number which corresponds to the numeral thrown on the dice. They place
their stone on the corresponding dots on the snake.
4. If another pupil is occupying that numeral, the pupil looks for the next unoccupied number corresponding to the
amount thrown.
5. The pupil who throws 1 (one) to land finally on the snake's eye, kills the snake and is the winner.
4. Game: Shop Race
You need: A Shop Race Board (This game can be found in the Printable Materials section), dice and
counters.

Up to 6 pupils can play in one group.
The pupils take turns (clockwise direction) to throw the dice.
They leave the school on a race to the shop.
Each pupil counts the number of spaces on the road to the shop as shown on the dice.
The road can have any number of hazards on it.
The pupil who reaches the shop first is the winner.
5. Game: Dominoes
You need: A set of 30 domino cards (see the Printable Materials section).
Four pupils per game.

Shuffle the dominoes by placing them face down on the desk.
The pupils take seven cards each. There will be two cards over which can be placed to one side.
Pupils arrange who goes first and they play in a clockwise direction.
The first pupil puts down a domino. It should be a domino with the two sides adding up to the largest score.
In the example below it is 4+ 6 = 10.
The next pupil tries to match a card with the ‘4’ or the ‘6’.
In the example the ‘6’ is matched with ‘6 dots’ and a ‘3’ at the other end and the next pupil has to match a
domino with a ‘4’ or a ‘3’.
If a pupil cannot match any card he misses his turn.
The pupil to finish all his dominoes is the winner. If no one can get rid of their dominoes, the total number
left in each ‘hand’ is added up and the lowest total wins.

7. Counting
Let pupils count various objects within the school compound:
1. Count while sorting and ordering activities.
2. Count paces (perhaps while measuring).
3. Count groups of children.
4. Count things in nature such as leaves, petals and clouds.
5. Count people or cars as they pass the school gate.
6. Count window panes or other objects in the classroom, etc.
8. Patterns
Allow pupils to experiment by drawing around shapes. Give groups of children a number (from 4 to 9) and let them
make patterns using cardboard squares, stones, bottle tops, etc. Working in pairs, one pupil starts a pattern using
sorting material. The partner then tries to continue the same pattern.

9. Partitioning
The partitioning of groups of objects is a very important early activity. A partition is something that separates, such
as a screen or curtain dividing a room in two.
Ask the children to place five objects in front of them. Let them partition the five objects, with a ruler or pencil, in as
many ways as they can. Encourage them to record their work as number facts of 5.
Now give a number to each of the groups (from 6 to 9) and let them find out how many different number facts they
can obtain from partitioning the numbers.

Later these number facts can be revised and used for introducing operations. This may be a good time to introduce
the "+", "-" and "=" signs:
1+4=5
2+3=5
3+2=5
4+1=5
10. Number Books
Children should be encouraged to make their own number books - finding out as much as they can about each
number.

own number lines:
