The first thing I noticed after reading this was there were no conjunction words. It is instead of it's. I cannot instead of I can't. That's because, at this level of reading, students don't know about the joining of two words.
The facial expressions in this book are very detailed and that is because kids at early reading levels can associate the facial expressions with the words. This book was about a button that had no meaning, it did nothing. But what three friends soon found out was that the button made them show their emotions. The button made Blue Bird Excited and surprised, it made Red Bird sad, then Happy. It made Yellow Bird happy, then mad, then funny. At the end of the story, all three friends were happy, and they all decided it was a button that made them feel happy.
The illustrations in this book were well done, bright colors, and the three main characters were the primary colors, three colors that early kids can point out. Also, the speech box of each character matched the color of their feathers, this will make knowing whos talking even easier for young readers, having the visual clue. Overall this was a very well done easy reader.
