Both you and your child may notice differences in the appearance of certain letters across the App activities, eBooks, and corresponding lesson workbook; such as the uppercase "I" or the letter "a". While our intention is not to cause confusion, we believe it is important to expose children to different types of print and fonts, as they will encounter various styles in real life. We recommend explaining to your child that letters can have different appearances depending on the style or typeface used, but they still produce the same sounds and are referred to by the same name.
