probably an assignment that needs to be handed tomorrow.
you've mentioned those ICs, search for the datasheet, and come again if you have any problems.

den hw to do it by theory??
-using sequential circuit design method
-truth table(present state, next state, flip-flop A to H), flip-flop A to H is use excitation table 2 state it
-k-map
-circuit diagram
 
For asynchronous mode of counting it is simple to construct a ripple counter using 4 JK and feeding following clocks with preceding outs.
 
Using 4 FFs you can count 2^4 states. Tie J & K inputs to +5V for all FFs. Connect external clock to first FF clock in. Following FFs clocks must feed with preceding outs.
