Watch the video and then have a look at home for some things that begin with n. Can you put them all together and make a collection? This is called a sound table. Write a label for your collection to help you remember what the grapheme looks like!
If you like this activity you could change your sounds table for each new sound you learn and take a photo each day. Once you've done this a few times you could even put the photos in a book to make your very own sounds book!
