This learning can be done on Seesaw or in your blue learning book.
Please write the matching cards into your book.
If you want to make them into a game you can print them out and cut them into cards. Or you can write them onto pieces of paper and play a matching game.
The rules are that they need to be face-down on the table. Take it in turns with someone in your house to choose 2 cards. If they are the singular and the matching plural you keep them and have another go!
For example - man and men.
If they do not match put them back, face down!
