Hints and Tips

Our familiarity with the metric system and decimal currency may seem to have made calculations with fractions less important but in many ways, it is more convenient to use common fractions in everyday life.

It is unlikely that we would ask for a 0.5 pint of milk, rather than a half pint. Also, it is easier to cut material into one third of a metre rather than 0.333!

When writing fractions in symbols, NEVER say over, line or slash.

These words mean nothing in this context and can cause confusion for your child. Use out of or divided by which have meaning. Blue Fractions 1

Essential Prior Knowledge

The meaning of the words:

denominator ( the number under the line in a simple fraction, showing how many parts the whole is cut or shared into)

numerator (the number above the line in a simle fraction showing how many of the parts needed)

 

Activity

You will need a copy of a fraction wall to play this game You could buy one or you could help your child to make one.

Fraction Target Game


Set up a target game for your child. This could be tossing a ball into a waste paper bin from a set distance or basketball hoops or penalty kicks.


Give him/her a try at the target game BUT restrict/define how many attempts he/she can have e.g. 2, 3, 4, etc., up to 20.

Record the successes on a chart as 1 out of 2 or 1/2, 4 out of 12 or 4/12, etc.

Talk to your child about the fractions. Is there any other way they could be written? Check on the fraction wall.

This activity can be repeated as often as your child likes varying the number of attempts at the target.
