In Room 8 Mr Tucker did a magic trick. Bianca chose a volunteer and it was Jack. Jack got a bit of paper and a pen and went to the back of the room to write a number between 1 and 63.
He came back and Mr Tucker turned to face the wall and Jack showed everyone in the class the number. We kept it a secret. It was 20. We did not call out the number.
Then Mr Tucker turned around and got some number cards. There were 2 that Jack chose. Later Mr Tucker gave the cards to Lucy. Then Lucy chose a card and gave it to Mr Tucker. He guessed the number. It was 20.
