a shape that has 2 dimensions, length and width, eg square
an object that has 3 dimensions, including, length, width and height. eg cube
used in statistics to map all possible outcomes of an event
a whole number that can be made by multiplying other whole numbers eg. 6 can be made by 2 × 3 so 6 is a composite number
In the fraction a/b, b (the bottom number) is the denominator. It is the number of equal parts into which the whole is divided.
two fractions are equivalant if they are equal, eg one half is the same as two quarters
to factor a number means to break it up into numbers that can be multiplied together to get the original number eg. 6 = 3 x 2 so, factors of 6 are 3 and 2
a Function Machine is a diagram that represents a machine that takes an input, applies a rule such as a set of operations and delivers the answer as an output
informal units are non-standard units of measure, like blocks, hands, paperclips etc.
an irregular shape is a shape which has sides and angles of any length and size that are not equal
the average of a group of numbers.
the middle number of a series of numbers placed in order
the middle number of a series of numbers placed in order
the number that appears most often in a set of numbers, eg 2, 2, 2, 3, 4, 5, 5 - the mode is 2
partitioning is a way of working out maths problems that involve large numbers by splitting them into smaller units so they’re easier to work with eg. 12 might be partitioned to 10+2, 148 might be partitioned to 100+40+8
a prime number is a whole number greater than 1 whose only factors are 1 and itself
the likelihood of an event occuring, can be expressed as a percentage or a fraction
the difference between the highest and lowest number in a set of data
a shape that has sides of the same length and angles that are all equal
the product of a number multiplied by itself, e.g.4x4=16 therefore 16 is a square number.
when two or more parts of a shape are identical after a flip, slide or turn
