This collection includes 20 sets based on sounds. This was created with help from my students who wanted a more challenging way to work with their phonograms. There are four sets pictured here. The children lay the heading cards out and place the cards with the missing phonograms in the correct column. A teacher can check them. If there are any that are incorrect, the child can use the dictionary to find the correct phonogram heading. Print on card stock, laminate and cut apart.
