Manatees Lead Teacher

Tasha Felder

My name is Ms. Tasha Felder and I have been teaching pre-school aged children for 15 years. I love teaching children, especially the little ones. I am one of the VPK teachers here at the UNF Preschool. I really enjoy working with this age group because the children are so eager to have new learning experiences. When I get to watch their excitement about learning how to do something new for the first time or making connections, it makes my day. I love to dance and do yoga and love even more that I get to incorporate into our day with the children. Having the children come up with their own projects has been so much fun.

I am the only child of two retired Navy parents. I have lived in Jacksonville most of my life, but was born in Hawaii and lived in Europe for 6 Years. I am excited to learn and grow with the Manatees! I feel very privileged working with the amazing team of teachers and staff at the UNF Preschool. I have a National CDA and I am currently taking classes towards my AA in Early Childhood Management with a concentration in Elementary Education.

Dolphins Lead Teacher

Aleris Mendez Roa

 I recently finished my A.A as well as my CDA. I'm currently taking classes towards my Bachelor's in Early Childhood Education. I've been working with children for about four years and that's when I fell in love with what I do and never want to stop. I would like to continue my education with a Masters in Special Education. My motto in life is, it's not about how small or how big the venture is, it's about doing something that's yours. I'm happily married and desiring a puppy. My hobbies are watching movies on Netflix with the worst ratings. I love to travel and would love to visit my home state Puerto Rico.

I love to bring different cultures to our classroom, I am very engaged and love to do many experiments with the children to help their learning. I love decorating my room to fit the theme that we are learning about. I love having fun with the children through dance and movement as well as our very creative story times!

Maria Beattie Headshot

Cardinals Lead Teacher

Maria Beattie, Bachelors in Elementary Education

I graduated from the University of Vermont with a Bachelor in Elementary Education and a concentration in Anthropology. I have worked with children of all ages but my favorite is preschoolers. When I am not teaching I enjoy fitness and being creative outdoors, theater, dance, music, reading and eating good food. I like to incorporate some of these interests into the classroom. I use a lot of music and movement, including dance, active games and yoga.

In my classroom, learning is very interactive and hands-on.  I believe in meeting each individual child where they are at and addressing their individual needs, while also challenging them to the next level in their learning.I believe that social and emotional development at this age is crucial and I work to teach the children how to interact with others, problem solve, and regulate their emotions.  I give children strategies, skills, and support to deal with different social and emotional issues that arise.  I think it is important for children to be able to problem solve with their peers and I encourage them to do this on their own when possible and give them support when needed. I’ve created an environment where I can incorporate learning into all of the centers.  Learning is always happening through play, so I am always thinking of different ways I can incorporate certain learning goals in the play that the children are engaged in.
