Create this kind of card by using masking tape to tape a border around the card (it actually helps to tape it down to the table). Then take a thin piece of tape and place it down the center, and do the same across the card, to create four blocks.
Using a separate piece of paper, outline letters or shapes and have your child color them in. Then cut them out and glue them into the squares on the card.
If you use colors that contrast enough, you don’t need to have a dark outline around the letters/ shapes. It’ll give it a great different look.
Helpful Hint: Use masking tape that’s cheap, so that it doesn’t stick too much to the card. And when you take the tape off, do it slowly and gentle so that it doesn’t rip off part of the card.
