Start by following the basic process for fraction multiplication, turning any mixed fractions into improper ones. Before you cross cancel or multiply, however, swap the numerator and the denominator in the second fraction. This is called taking the reciprocal and it is the key step to turn this into a division operation. Then, cross cancel, multiply across to get the answer fraction, and reduce.
Understanding decimals is vital for real-life, everyday maths. Phoebe Doyle offers some teacher tips to help your Key Stage 2 child understand what decimals are and how to use this knowledge in calculations.
Practicing addition with your child is a great way to get him excited about math! Young kids who are beginning to learn addition often need to see a visual representaion of any given problem. Many kids will use their fingers and toes, but make things more fun by using counters. You can use pieces of cereal, beads, mini marshmallows or anything you would like. Kids love switching things up with large-sized counters, so bust out pillows or purses to make learning addition even more fun.
If a child is really confused about decimals, converting decimal numnbers into money is a great way to make things clearer. For example: a child may be asked to say how much bigger 1.3 is than 0.9. If they convert these decimals into money (£1.30 and 90p) they may find that they can do this calculation very quickly in their head, getting the answer 40p which they convert back into the decimal, 0.4. Demonstrating that money maths depends on decimal understanding is also an easy way to prove that decimals are actually useful in real life!
