Addition and subtraction of 3 and 4 digit numbers
Eg 3543 + 5642, 7845 – 3452
Remember to put the numbers into columns according to value, eg hundreds tens units.
Multiplication of 3 digit numbers by 1 digit number
Eg. 463 x 7
Use the box method to help you remember to multiply each part individually.
Division of 3 digit numbers by 1 digit number with and without remainders
Eg. 579 ÷ 6
Remember to read the question to find out if the answer should be a remainder or a decimal answer. Then use long division.
BIDMAS
Order of calculation. Brackets, Indices, Division, Multiplication, Addition, Subtraction
Understanding fractions as part of a whole
Eg. 3 parts of an 8 slice cake = ⅜
Remember that the answer will be a fraction and that the denominator(bottom number) will be the number of slices of cake
Cancelling down of basic fractions
Eg. 9/12 = ¾ and 5/10 = ?/2
Try and find a common number that we can divide the numerator(top number) and the denominator by
Recognising simple equivalent fractions
Eg. ½ = 2/4 = 4/8 = 6/12
Equivalent means the same. The numbers may not be the same but they can cancel down to give the same answer
Understanding of place value to multiply and divide whole numbers by 10 or 100
Eg. 76 x 100, 560 ÷ 10
Add and subtract decimals to 2 decimal places
Eg. 3.06 +12.1, 13.5 – 1.45
Use column addition to help you with which numbers to add together
Being able to fill in the missing gaps in equations
Eg. 5 x ? = 45, ? + 4 = 7
Collecting like terms
Eg. a + a = 2a, a + b + a + b = 2a + 2b
Like terms are terms that are similar. This means they have the same letter, or no letters.
Solving simple equations
Eg. a + 3 = 7, a = 4
Multiplying out brackets
Eg. 2(x + 4) = 2x + 8
Remember to multiply everything inside the bracket by the number outside
Understanding shapes, area and perimeter
Eg. recognising simple shapes: squares, triangles, finding the area and perimeter
Remember that area is the amount of space a shape takes up, and perimeter is the distance around the edge of the shape
Being able to recognise odd, even, prime, square and triangle numbers, and identifying factors of a number
Odd numbers cannot be divided by 2 to give a whole number answer
Even numbers can be divided by 2 to give a whole number answer
Prime numbers can only be divided by themselves and 1 to give a whole number answer
Square numbers are numbers multiplied by themselves
Triangle numbers are the number of dots we need to make a triangle
Being able to use tally charts to record data and how to use bar charts, line graphs and scatter graphs
Remember that all graphs we draw have got to have a labelled x-axis and a labelled y axis
Being able to solve a variety of different money problems, including adding, subtracting, multiplying and dividing.
