Using Dice In Algebra

 

Most schools have sets of dice in every math classroom.  Usually, dice are used to teach probability because they are very visual and many standardized test questions ask questions about dice.  However, there are other ways to use dice to actually help teach algebra and we'll look at ways to use them in Algebra. 

Dice can be used to help create algebraic expressions or equations.  If you use two different colored dice, one represents positive numbers while the other represents negative numbers.  Think about rolling two dice and you have the coefficients for your equation.  Role multiple dice to find the coefficients for a bunch of terms that students can then combine and simplify.

In addition, dice can be used to generate the terms of two different equations that make up a system of equations.  Students then solve the system to find the values for x, y, and even z if you have three equations you are solving.  Rolling the dice allows students to create unique equations to solve and it involves students more in the whole process.

Another use of the dice is to find a number that can be factored as the first step in factoring.  The dice can also be used to find the coefficients for a binomial or trinomial equation or expression to be factored. Again, when you roll the dice, you have equations that are being made immediately and every student has a different equation.  

Furthermore, dice can be used to find numbers that students use to create inequalities.  The numbers could be whole, fractions, or even in decimal form.  One can even set up multiplication problems to be compared such as 2 x 5          3 x3  and students are asked to compare them.  So many different ways to create inequality problems with dice.

Finally, create games that have students create the equations, variables, inequalities, etc and then have them solve the equations.  Those who solve the problems win points.  When you use dice and have students use them to create problems, they become more involved.  Let me know what you think, I'd love to hear.  Have a great day.
