Students get with a partner (or work alone) a= nd generate linear equations “hidden away in the recesses of their calculators”, solve the equations, score points, and then check their= own answers.

 

1.&n= bsp;     Use RandInt to generate a random equation of the “<= span class=3DSpellE>ax+b=3Dc” variety.

 

 <= /span>

2.&n= bsp;     Use the “8,-8,3” to create the equation “8X-8=3D3”

 <= /span>

3.  Solve the equation for X (by hand)= .  Note in this case X=3D11/8.

 <= /span>

3.&n= bsp;     Check th= eir answers using the “Solve” feature of the TI-84.  After entering the equation in the “Equation Solver”, press “Enter”, then arrow down to “Solve: X” and press “Enter” again.  The correct solution is listed in = the “X=3D” slot.

 <= /span>

 

        

 

 

4.&n= bsp;     Make up scoring rules such as:  if the answer is correct 5 points.  L= et the value of X  (or absolute value if X is negative) be the bonus points.  5 bonus points if answer is “= ;no solution”.

 <= /span>

5.&n= bsp;     Game is = over after 5 rounds or when a player scores 21 points.

 <= /span>

Note= :  This can be extended to equations of the form “a(bx+c)=3Dd” by changing the “randInt” command to 4 instead of 3...etc.
