Title

Comparing Decimals Game

Lesson Objective

The student will read, write, and compare decimals to thousandths based on meanings of the digits in each place, using

>, =, and < symbols to record the results of comparisons.

Background Information for Teacher

The teacher can play against the student if no other participant is available. Words in bold are said aloud by the teacher.

Student Prior Knowledge

N/A

Materials:

● Comparing Numbers With Decimals worksheet (Step 3)

● 1 deck of cards (with Jacks, Queens and Kings removed)

● 1 pencil

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

play)

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.

Have the student read the entire sentence: 68,721.314 is greater than 67,943.421. Now ask them which number is

smaller.

Tell the student to read the entire sentence: 67,943.421 is less than 68,721.314.

On page 2, the teacher writes their number in the Player 1 space and the student writes their number in the player 2

place. Ask the student which one of the symbols belongs in the middle, <, =, or >

Explain that player one always writes their number in the Player 1 place and player 2 always in the player 2 place, but you

will write a different symbol based on who’s number is greater.

Circle or highlight the greater number to show which partner won this round.

Give students time to play the game with another partner(if no other participant is available the teacher can replay with the

student).

Repeat game as many times as needed until student show complete understanding of the lesson.
