My son struggles with letter formation & staying on the line. This book has been AMAZING for him. The individual boxes force him to focus on a letter at a time with no pressure. I ask him to space a box in between each word & it has made a world of difference. I can read his work so much easier & his confidence has increased. I purchased an additional two books for him for school & his teacher agrees this book has been great for him. I’m very happy & will continue to purchase as needed!
