Encourage your child to join in with the singing, whilst doing the appropriate action. A good number of schools use the Jolly Phonics mnemonic actions (memory aids) to help children remember the sound each letter represents.
Select the set of graphemes for your child to practise by clicking the circle to the left of a set of letters. A grapheme appears in one corner of the screen. Bubbles float across the screen with graphemes attached underneath and your child has to pop the ones which match the grapheme in the corner of the screen.
Call out a sound. Get your child to select the corresponding grapheme from the left hand side of the screen - it will be fired out of the cannon. From ictgames.com
Select a letter your child needs to practise. Watch a plane write it using its vapour trail, getting your child to follow the trail with his/her finger on the screen, saying the sound at the same time.
A whiteboard with letters of the alphabet along the bottom. Call out a sound and get your child to click on the corresponding letter for it to appear on the whiteboard.
Great video for teaching children that when we have a digraph containing 2 vowels, the sound they make together is often the name of the first one. This works for the digraphs 'ai', 'ee' and 'oa', that the children learn at this stage. NB: We don't generally teach 'y' as a vowel in this country, so the 'ay' image will need some explaining (or ignoring!)
Great video for teaching children the 'ar' grapheme.
Below are links to a variety of creative trays you can make and use with your child to help him/her learn to write letters/graphemes. Select one that links to your child's interests or the current time of year, as this should motivate him/her to write. Call out a sound (phoneme) and get your child to write it in the tray.
