Answer-Worksheets are not a developmentally appropriate tool for two, three, and four-year-olds. This means that Julia's activity does not meet NAEYC standards. According to NAEYC, young children learn best through hands-on, play-based activities that are appropriate for their developmental level. Worksheets are not considered to be an appropriate tool for young children because they do not engage children in active, hands-on learning. Instead, they promote passive learning and rote memorization, which are not effective strategies for young children. To meet NAEYC standards, Julia should consider using play-based activities that are developmentally appropriate for each age group, such as sensory play, block play, dramatic play, and art activities.
