Research shows that math games and puzzles can dramatically improve your students scores and enhance a love of learning about mathematics.
Using games makes understanding difficult concepts much
easier. This is especially important for students who may be struggling
with understanding how our number system works.
According to a recent study by Seigler and Ramani, students show
significant increases in number sense when playing games. This is also
supported through research conducted by the Carnegie Mellon University.

In fact, students who play board games show a statistically greater
advantage in math over students who engage in little to no time playing
games.
The studies also show that teachers can improve conceptual understanding, application, mental
math, and problem solving skills simply by using math games as a regular
part of their lesson plans.
It is recommended that teachers send home math games and puzzles for
parents to play with their child. This offers a great opportunity for
parents to be involved with their kids education in a nonstressful
environment, which will also help build positive feelings about learning
mathematics.
Clear the Ten Frame
You will need three dice, 10 markers and a Ten Frame. To teach the game I draw a Ten Frame on the board and put an X in each square. When the students play it with a partner, they will use the markers and place them on the Ten Frame to start the game.
1. Roll the three dice and write the numbers on the board.
2. Ask the class to describe any ways they can see that they can make the number 10 (the last square on the Ten Frame). If they can, remove an X. Now you are showing the number 9. Ask them if they can use any of the numbers to make 9. Continue this pattern until you have to roll the dice again (there is no way to make the next number). You cannot skip a number (say you are on 5 but they can see a way to make 3. You cannot do it until 5 and 4 have been made and removed).
3. One, two or all three dice can be used.
4. The game is finished when every number has been made, in order.
Going to Boston: Math Facts
This easy math game requires three dice and pencil & paper.
In one turn, the first player rolls all three dice. The highest
roll is put aside. The next two dice are rolled and the highest number
is put aside again. The last dice is rolled, then all three dice are
added together.
The winner is whoever gets to a predetermined amount first, such as 100.
Variations on the game are adding the first two dice and
multiplying the sum by the third; using any combination of addition,
subtraction, multiplication or division to get the highest number
possible, or just using two dice to practice basic math facts (addition,
subtraction or multiplication).

Sums Stacker  Carstens Studios Inc.  this awesome app has won numerous awards for both function and design. Kids play with numbers and develop deep levels of number sense. It is sold as an iPhone app, but is compatible with the iPad and the iTouch.
Money Grab Bag
Place a variety of coins in a bag. Students pair up and each one takes a
handful of coins from the bag. They count their coins and the one with
the largest amount wins.
There are many variations to this game. Ask the students to identify and remove all of the quarters before counting. They could work on counting on, finding the difference between the two amounts or showing the same amount in another way.
Fraction Dominoes
You will need a set of Fraction Dominoes
for this game. You can make them yourself, but it takes a while. The
students will match the fractional picture with the written form. You
could also extend it by having them write the ratio or percent shown on
the dominoes.
Climb the Ladder
Provide students with a paper with 10 blank lines. At the bottom (under
the first line) instruct them to write a target number. Depending on
your level, it could be "6" or "560." Once you say, "Go!" time the
students for 5 minutes. They have to climb the ladder by writing
different ways to show the target number.
For example, "6" could be shown as: 5 + 1, XI, 2 x 3, 10  4, etc.
