Pedigrees are basically a map of alleles for family trees
 
                   ______Person1 -- Person2_____
                  I                I                  I                 I
        __Person3_   Person 4     Person5    _Person6___
       I                   I                          I            I                    I
   Person7 Person8                 Person9   Person10  Person11
And under everyone's name you write their alleles.
Punnett squares give the probability of someone having genes based on their parents' genes.
 
                             Parent1 (Aa)                   or                      Parent1 (aa)
 
Parent2 (AA)        AA      Aa                             Parent2 (Aa)     Aa      aa
                             AA      Aa                                                       aa      aa
