**Roll and Scroll game**

* Two students can do the activity.

* Make a number board with numbers from 1 to 37
as shown in the picture.

* The first player throws a dice and a number
appears on the face of the dice say 2.

* The other player places a coin on the number 2
and skips to number position in twos such as 4,6,8,10 and so on till the last
number. The first player records each of the number positions.

* Now, the second player gets the chance to
throw the dice. When the number 2 appears again the player tells all the number
positions jumped orally. If he gets a number 3, then the first player moves a
coin by skip counting in threes.

* The second player record each of the number positions jumped. The above procedure is continued till the players are familiarised with the number patterns starting from 2, 3, 4, 5 and 6.
