- Prepare the envelopes in advance by writing a name and address, sticking a stamp and writing a number on the front of each envelope. Make enough envelopes as children in the class or ask the children to work in pairs.
- Make a letter box using an old box. Cut a vertical hole in the lid (large enough for your envelopes to drop through) and decorate the outside.
- Similarly, in advance of the class, hide the number cards in different places in the classroom.
- Using a toy telephone, pretend to receive a phone call from the postman who cannot do his run today because yesterday’s storm blew away all of his letters. He asks for help from the children to collect the letters and put them back in the appropriate envelopes.
- Give an envelope to each child or pair of children in the class.
- Tell the children that there are number cards hidden in the classroom. They should look for a number card that matches the number on their envelope. Once they find the matching number card, they put it in their envelope.
- Once all of the children have found the number cards, show the class the letterbox and ask them what it is. Ask them to stand in line in order (1-20) to ‘post’ their letters in the class letterbox.
- At the end of the class, you can give out all the envelopes again and include a dot-to-dot activity as if it were a present from the postman for helping him out.
