Previously Published Data 

1.) Students begin with a set of cards (ten numbered "1"; ten numbered "10"; ten numbered "100".) On their record sheet they begin with the right hand column and enter zero in the Ones column. Draw a one, record "1". Each time a "1" is drawn, it is added to the previous total and recorded. When the tenth "1" is drawn, record "0" in the Ones column and "1" in the Tens column. Bring back the ten "1" cards, continuing adding one at a time and recording. What patterns do you notice on your recording sheet? Can you predict if these patterns will continue? How often will they repeat? Why?  

2.) Using a set of cards with the digits "0" through "9" written on them, draw five cards at random. Organize these cards to make the greatest number possible and record your number; then organize and record to make the number with the least value. 

3.) Using the "0" to "9" cards, draw two cards and record them. Next round them to the nearest ten. Round up if the digit in the ones place is five or more; so, 15 through 19 become 20 while 10 through 14 become 10. Repeat the drawing eight times and show your work to your teacher. With your teacher's approval, start a new version of the game by drawing three cards at a time. Record them and still round to the tens place (715 becomes 720 and 873 becomes 870.) After doing this eight times and getting your teacher's approval, use these same eight numbers and round them to the nearest hundred. Now, 715 becomes 700 and 873 becomes 900.
