T: you count from one in turns and every second number you say beep. For example: one, beep, two, beep, etc. (Students alternate between saying a number and the word “beep” as they go around the room counting. For example, the first student would say, “one,” the second would say, “beep,” the third would say, “three,” the fourth would say, “beep,” and so on.) T: now you count but you say beep for odd numbers. 1, 3, 5, 7 are odd numbers. (However, you can make this game as complex as you want, such as choosing to insert “beep” for odd or even numbers, on numbers divisible by three, etc. You could also bring it to the next level by creating other sounds or words they have to say for certain numbers. For example, every number divisible by three must be replaced by “beep,” and every odd number must be replaced by “boop.” For numbers that fall into both categories, you must say both (“beep boop”).)
