Divides exactly into a number- eg. 5 is a factor of 10

1 of 22

Type of number:multiple

in the times table of a number- eg. 20 is a multiple of 10, 25 is a multiple of 5

2 of 22

Type of number:square number

can be written as a number multiplied by itself- eg. 9 is a square number because it can be written as 3x3. The first 7 square numbers are 1,4,9,16,25,36,49.

3 of 22

Type of number:prime number

can only be divided by one and itself: 2,3,5,7,11,13,17... are prime

50%=0.5=1/2...divide by 25%=0.25=1/4...halve then halve again 10%=0.1=1/10...divide by 10 1%=0.01=1/100...divide by 100

Angle rules:

opposite angles are equal anlges at a point add up to 360 angles in a quadrilateral add up to 360 alternate angles in parallel lines(Z angles)are equal corresponding angles in parallel lines(F angles)are equal

17 of 22

Angle rules:

Interior angles in parallel lines(C angles)add up to 180 angles on a straight line add up to 180 angles in a triangle add up to 180

Special words:

sum: add the words together product: multiply the numbers difference:biggest take away the smallest estimate:round the numbers first and give an approximate answer

19 of 22

Special words:

solve: work out the value of the letter correlation: the relationship between 2 variables, can be positive,negative or no correlation. draw a line of best fit if correlation is positive/negative.

20 of 22

Special words:

expand: multiply out brackets 2(x+3= 2x+6 factorise: put brackets back in x -3x= x(x-3) tessellate: fit shapes together with no gaps

21 of 22

Averages:

mode/model: the most common values or value median: the middle value when they are in order mean: add up all the values and divide by the number of terms range: highest value take away the lowest value
