Place-Value Card Game
Number Top-It
Purpose:
The objective is to understand place-value in 7-digit numbers.
Materials:
You need number cards 0-9 (four of each) and a place-value mat (see attached).
How to Play:
The goal is to make a larger 7-digit number than your opponent.
1. Shuffle cards and place them face-down in a stack.
2. Players take turns drawing seven cards, one-at-a-time.
3. Each time a player takes a card, he/she determines the place-value
column for the card. Once a card is placed down on the mat, it can not
be changed.
4. After all seven cards have been drawn and placed on the mat,
players read their numbers aloud and compare them.
5. The player with the larger number wins the round. Play five rounds.

Sam’s 7,973,524 is larger than Jan’s 7,645,201 so Sam wins the round.
Game Variations:
 Change the rules: smallest 7-digit number wins.
 Create larger numbers: make a mat for 10-digit numbers.
 Build numbers with decimals: make a mat with tenths and hundredths.
Reading Numbers:
Large numbers are read by naming the period of each group of three
digits. Each group of three digits is separated by a comma. The
numeral 3,456,789 is read as three million, four hundred fifty-six
thousand, seven hundred eighty-nine.
