It can be hard to tell the difference between M and N! They look and sound similar—and when sung in the alphabet song, they tend to blend. This book for pre-readers takes M, N, O, and P one at a time, aiding readers in recognizing each—including the troublesome M and N! Each letter is shown in both upper and lower-case forms, and readers are invited to trace each with their finger, engaging in pre-writing activity. Words showcasing each letter in the initial position are included with an accompanying full-color photograph to aid readers' comprehension.
