As children approach pre-school age, they'll often begin to build their understanding of the different sounds that make up words and be able to spot similarities and differences between different words.
You can put this to the test by playing some fun rhyming games.
Dr Saloni Krishnan helps one family realise how much their child understands about word sounds in our Speech Lab - check out the video below.
Try out this rhyming experiment at home
Try making a few flash cards for your child with animals with names that rhyme on them - e.g. Cat, Bat, Rat - and others that don't - e.g. Fox, Cow, Pig.
Present them with a group of these in turn, reading them out loud as you show them the cards.
First, present them with 4 cards, 3 with rhyming names and 1 that doesn't rhyme - Cat, Rat, Fox, Bat, for example. Ask them 'which one sounds different?'. Can they name the right card?
Next, present them with 4 cards where none of the animals' names rhyme - Cat, Fox, Pig, Hamster, perhaps. Ask them, 'does one of these sound different?'. Do they have an answer this time? Or are they unsure?
If they're able to answer the first question, it shows they're looking out for similarities and differences in the sounds that make up words.
What's going on in your child's brain when they understand rhyme?
Scientists have found that children aged between four and five often use an area of the brain called the dorsolateral prefrontal cortex when they hear rhyming words. This part of the brain helps them remember similar sounds in words like the 'ee' sound in 'tree' and 'bee'.
This means that playing with rhyming words and sounding them out can be a great way to help your little one recognise the sounds and patterns in words, a key skill that they will need when it comes to learning to read.
Building phonological awareness
Awareness of the individual sounds that make up words is sometimes referred to as 'phonological awareness'. This is a great thing to have when children start school.
There are lots of games you can play to help your child build phonological awareness.
1. Sound sorting box
Children can learn all about the sounds that start words by playing the 'sound sorting box' game. All you need is some household items and a box to put them in.
2. Hopscotch
Hopscotch can easily be turned into a game for learning about letter sounds. Try drawing letters instead of numbers in the hopscotch grid and then when their stone lands on a letter, get them to think of a word starting with that sound by the time they skip over to it.
3. Sound treasure hunt
A sound treasure hunt is another fun way for children to practise word sounds. Can they find an object that starts with a 'c' sound? How about a 'b' sound? This game can be played at home or out and about in places like the supermarket.
4. I Spy
I Spy is a classic game for teaching about words that start with certain sounds. But you could even give it a twist and 'spy' objects that rhyme with other words!
