A good air transportation theme is on most SLPs' calendars. This packet of articulation activities is a great packet if you don't have a lot of time to prep. Two of the activities are NO PREP! The last one is a craftivity but the only material you need is blue construction paper.
ONE open ended activity
ONE coloring activity that addresses initial sounds only (b,p,m,k,g,f,v,r,s,l,z,sh,ch,j,th and blends)
ONE craftivitiy that addresses sounds in all positions (except blends)
