S1 Information Night Block 1 Level 2 Rounding Percentages Time Length and Area Statistics
Rounding and Estimating Key Points o 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. oTo decide how we round follow the rule 5 or more round up, 4 or less round down o Pupils will regularly be practising their times tables as well as having access to times table grids to aid with the work. o 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 o To convert and percentage to a fraction ?????????? then simplify eg 17% =17 100 100 20 100=1 o Fractions should be given in their simplest form eg 5 o 17% as a decimal 0.17, 20% = 0.20 , 4% = 0.04 o50% = 1 2,20% = 1 1 4, 10% = 1 5 ,25% = 10

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