My son loves the Little Critter workbook series, and I've had a good opinion of them until this one.
Most of the activities are selecting pictures based on the beginning consonant sounds. There is only one page for all five vowels, and no distinction between short and long vowels. I think they should have at least had one page per vowel.
The other big problem I had with this particular workbook is the pictures that they use, and the way that "X" was handled. "Box," "fox," and "mailbox" were used for letters B, F, and M...but they were also used for the letter X. My son was confused because all the other consonants had emphasized beginning sounds, but the X page emphasized ending sounds only. How hard is it for Spectrum to pick up a dictionary, and look in the X's for words that start with X?
I realize that the beginning sound of X is similar to Z, but it's not any different than C and K sounding similar.
I was also disappointed with the number of pages that were simply scenes to be "discussed." I could do that with any storybook. I felt like this workbook was mostly a waste of paper.
I suggest passing on this one, and just getting Spectrum Beginning Phonics (Little Critter Workbooks) instead.
