Rounding and Estimating Key Points For this topic pupils knowledge on place value is vital eg 5768 (5 thousands 7 hundreds 6 tens 8 units) especially when it come to rounding to 100, 1000 etc. To decide how we round follow the rule “5 or more round up, 4 or less round down” Pupils will regularly be practising their times tables as well as having access to times table grids to aid with the work. Pupils are taught the mathematical methods to multiply and divide by 10, 100, 1000 however we enforce the quick method (x10 add a zero , x100 add 2 zeros, x1000 add 3 zeros and vice versa). The quick method is only used for whole numbers.

Percentages Key Points To convert and percentage to a fraction 𝑝𝑒𝑟𝑐𝑒𝑛𝑡𝑎𝑔𝑒 100 then simplify eg 17% = 17 100 Fractions should be given in their simplest form eg 20 100 = 1 5 17% as a decimal 0.17, 20% = 0.20 , 4% = 0.04 50% = 1 2 , 20% = 1 5 , 25%= 1 4 , 10% = 1 10

Length and Area Key Points Being able to identify the correct measurement unit and measuring exact lengths in a variety of different units. Perimeter is the total distance around the outside of the shape. Area is the amount of space inside the shape. Area of a Rectangle = Length x Breadth Area of a Triangle = 1 2 x base x height Area is always measured in 𝑢𝑛𝑖𝑡𝑠 2
