Step 2: Teach Lesson
Tell the student that today we will be learning about comparing decimals to thousandths.
Show the student the Comparing Numbers With Decimals worksheet (Step 3) and read the directions.
The teacher selects a card from the deck (if you have not previously set aside Jacks, Queens, and Kings, do this as you
Think aloud as you choose where to place the number you selected. “I chose a 3, this is a small whole number, but
it’s not the smallest whole number. If I put it in the Ones place it will have a value of only 3, but if I put it in the
Thousands place it will have a value of 30,000. I’m not sure what to do… What value will this 3 have if I put it in
the Hundreds place???”
Tell the student to select the next card and have them decide where to put the card and state the value based on the
place they chose (If more than one student is participating you may wish to let the student call on a friend for advice, or
have the other participants shout out where he should place the card).
Continue until all of the spaces are filled in.
Read your final number in the correct form. “My number is 67,943.421.
Have the student read their number and help them read it in the correct form. “Our number is 68,721.314”
Now ask the student who has the greater number.
