Sturdy and perfect size for early learners. I like that all words start with a capital letter – which is different than most sight word cards – as it helps with recognition in books. Wipes off easily with no staining. Comes with a few blank cards to make your own. I wish there was a second set to continue to build sight word skills. It states first 100 sight words but two cards are blank (make your own), so four words are missing from the list such as “me”. A few of the “start here” arrows are different than how I would teach someone to start writing the letter (I write the vertical line for “T” before I write the horizontal line, although my husband would argue differently). My five year old struggles to use the guiding lines and green blocks to control the starting point and size of the letters.
