With it being assessment week next week, the children will be recapping a variety of objectives that they have learnt throughout the year. They will be focusing on measurements and converting between each one.
Converting between metric and imperial units
Here are some examples of metric and imperial measures of length, mass and capacity:
||mm, cm, m, km
||inch, foot, yard, mile
||mg, g, kg
||ounce (oz), pound (lb), stone
||ml, cl, l
You will be expected to know some common conversions between metric and imperial units. Some of these are shown below, but check with your teacher which ones you need to learn.
- 1 km = 5/8 mile
- 1 m = 39.37 inches
- 1 foot = 30.5 cm
- 1 inch = 2.54 cm
- 1 kg = 2.2 lb
- 1 gallon = 4.5 litres
- 1 litre = 1 3/4 pints
Next week in Maths, we will be recognising the percent symbol (%) and understand that per cent relates to ‘number of parts per hundred’ and write percentages as a fraction with denominator 100, and as a decimal.
Per cent means ‘out of 100′
The sign % stands for ‘per cent’ which means ‘out of 100′.
- 40% means 40 out of 100
- 11% means 11 out of 100
Converting between percentages and decimals
To change a percentage to a decimal, divide by 100.
Change 48% to a decimal: 48 ÷ 100 = 0.48
To change a decimal to a percentage, multiply by 100.
Change 0.67 to a percentage: 0.67 x 100 = 67%
For extra support on this area, check out the bbc website that has a fun video on decimals and percentages for the children to use.
Next week in Maths, the children will be focusing on addition and subtraction using the column method. When writing down sums, separate the numbers into units, tens, hundreds and thousands. List the numbers in a column and always start adding with the units first.
So when adding together 7948 + 1223, you should write it down like this:
Writing it down
If the numbers are too high or too difficult to subtract in your head, write them down in columns. Always start subtracting with the units first.
