Decimal Games

First, shuffle the dominos in the middle and take 3 of the dominos each. 

Decide if you are looking for the biggest number or the smallest number.

Next, students place the first domino in front of the decimal point to represent a number with tens and ones (for example, 4 and 2 would be 42). The other domino goes behind the decimal to make a tenth and a hundredth. 

Use a place value mat if needed. 

Students compare their numbers and decide who is the winner. 

Keep a tally chart to find the winner after 5 rounds.

First, choose five dominoes and turn them over. 

One side is the whole number; the other side is the decimal. Order the decimals from least to greatest or greatest to least. 

Want to make it a game?  Partners order their dominos then find the difference between their greatest decimal and least decimal.  The partner with the greatest (or least) difference wins.

First, choose two dominoes and turn them over. 

For our example we wanted to find the smallest number that could be made. 

One side is the whole number; the other side is the decimal. Compare both dominoes. 

Want to make it a game?  Each partner chooses one domino.  Then, they compare their decimal.  The partner with the greatest (or least) decimal wins.
