Numbers (This is one of my favorites.)
In this activity students read numbers in the order they like, or one chosen by the teacher. Their partners write the numbers as they are read. When finished, they confirm the information has been correctly transferred.
For a bit more fun with numbers, give students sets of number cards and have them work in pairs or teams. One person turns over a card and reads it to his or her partner who is at the board writing. When the student makes a mistake the speaker has to correct them. This works brilliantly because students are trying to go quickly to get through their pile of cards as fast as they can, but quickly find that they need to slow down to win. Slow and steady makes for clear communication and gets the best results.
