YEAR 8 LAC MATHS SEPTEMBER

1.          STATISTICS  -  The study of facts about numbers.

2.          BAR-CHART  -  A diagram made up of bars.

3.          PICTOGRAM  -  A pictogram is a diagram which uses pictures instead of bars.

4.          PIE CHART  -  A circular diagram where the angle of the slice represents number of items.

5.          CO-ORDINATES  -  In maths we need to the mark position of things at points.  We use two numbers called the co-ordinates.

YEAR 8 LAC MATHS OCTOBER

1.          LINE SYMMETRY  -  A line of symmetry divides a shape into two equal parts.  Each part is a reflection of the other.  If you fold the shape along this line, each part fits exactly on top of the other.

2.          TURN  -  We use the word turn to describe something that moves around in a circle.

3.          ROTATIONAL SYMMETRY  -  A shape has rotational symmetry if it fits on top of itself more than once as it makes a complete turn.

4.          ORDER OF ROTATIONAL SYMMETRY -The number of times that the shape fits on top of itself in one complete turn.   It must be two or more.

YEAR 8 LAC MATHS NOVEMBER

1.          MULTIPLES  -  The multiples of 2 are 2,4,6,8.....  The multiples of 3 are 3, 6, 9, 12……. etc.

2.          FACTOR  -  A number that divides exactly into another number.

3.          HIGHEST COMMON FACTOR  -  The largest factor shared by two numbers is their Highest Common Factor.

4.          PRIME NUMBERS  -  Prime Numbers have only two factors, themselves and 1.

YEAR 8 LAC MATHS DECEMBER

1.          EQUILATERAL TRIANGLE  -  An equilateral triangle has three equal sides.

2.          ISOSCELES TRIANGLE  -  An isosceles triangle has two equal sides.

3.          SCALENE  -  A scalene triangle has no equal sides.

4.          QUADRILATERAL  -  A quadrilateral has four sides.  Here are some:-

YEAR 8 LAC MATHS JANUARY

1.          PRISM  -  A Prism has the same shape the whole way through.

2.          CUBE / CUBOID  -  A prism takes its name from the shape of it’s ends.  Some prisms have special names.  A Cube and a Cuboid are special prisms.

3.          PYRAMID  -  A pyramid is a solid whose edges meet in a point.  A pyramid takes it’s name from the shape of it’s base e.g. a square pyramid.

4.          TETRAHEDRON  -  A pyramid with a triangular base is called a Tetrahedron.

YEAR 8 LAC MATHS FEBRUARY

1.          DECIMAL POINT  -  The word Decimal comes from the Roman word for 10.  The Point marks where the whole numbers end and fractions of numbers begin.

2.          PLACE VALUE  -  The position of a digit in a number affects it’s value.

3.          POLYHEDRON  -  A Polyhedron is a solid whose faces are all flat.

4.          NET  -  A net is a pattern of shapes on a piece of paper or card.  The shapes are arranged so that the net can be folded to make a solid.

YEAR 8 LAC MATHS MARCH

1.          PROBABILITY  -  In maths probability means how likely something is to happen.

2.          RANDOM  -  If a person is chosen at random it means that every person has an equal chance of being chosen.

3.          ALGEBRA  -  Algebra is a short way of writing mathematical rules.  It uses letters and symbols to replace words and numbers. 

4.          FORMULA  -  A rule written out in algebra is known as a formula e.g.  -  t=cx4  r=p+k.

YEAR 8 LAC MATHS APRIL

1.          RIGHT ANGLE  -  A quarter turn is called a right angle.  The corners of squares and rectangles are right angles.

2.          DEGREE  -  We use degrees (written °) to measure angles.

3.          ACUTE / OBTUSE / REFLEX ANGLES -                             

An acute angle is less than 90°

An obtuse angle is between 90° and 180°

A reflex angle is between 180° and 360°.

4.          OPPOSITE ANGLES  -  Opposite angles are equal.

YEAR 8 LAC MATHS MAY

1.          NEGATIVE NUMBERS  -  Numbers with minus signs in front are called negative numbers.

2.          POSITIVE NUMBERS  -  Other numbers are positive.  Positive numbers are sometimes written with a + sign in front.

3.          ORIGIN  -  The point at which the x axis and the y axis cross is called the origin.  The co-ordinates of this point are (0,0).

4.          QUARDRANT  -  The x axis and the y axis divide the space into four quadrants.  The quadrants are always numbered anti-clockwise.
