ready to write the numerals and their number names. Th
Procedure:

To form a seven-digit number, spin the spinner and
note the sector where the arrow stops, then draw one TL L TTh Th H T O
digit card and place that digit in the corresponding 7 6 0 9 1 3 5
column of your place value chart. If the spinner lands
on a column that is already filled, return the drawn card to the pile, reshuffle if you like,
and spin again. Keep spinning and drawing cards until all the seven columns are filled
with a digit. Now, write down the seven-digit number in numerals along with its number
name. Repeat this process to produce at least five different numbers.
