Steeped in science and story, the InvestiGators™ connect children to their world.

STEM + Art = STEAM

Through investigation and hands-on projects, children learn to think like scientists, construct mathematical concepts, appreciate fine art and music, use simple tools and machines, invent, and create.

Language and Literacy

We develop young readers by fostering imagination and a love of books and storytelling. Through quality interactions with peers and adults, children build a strong foundation for literacy, communication, vocabulary development, writing, and verbal problem solving.

Social and Emotional

Stories, characters, and play-based activities build bridges to the real world and inspire children to talk about and practice social and emotional skills, such as empathy and kindness, sharing, taking turns, and self-regulation.

Physical Development

Every InvestiGator Club day is filled with active indoor and outdoor play. We know that physical activity is not only important for good health, but also for engaged, mindful learning.

Words That Matter

We love the curriculum! The InvestiGator Club allows me to be flexible with my lessons to switch what I need to, to add more lessons when we have free time and to build onto what we learned in the morning for my extended care students. I’m very happy that we got it!!

My students are totally engaged with the new curriculum.  It reaches all the learning styles (auditory, kinesthetic, visual, etc.). The children have come to love the puppets and have make connections with these characters, as we have moved through the units of study. I like how the curriculum gives differentiation tips, ESOL tips, etc. throughout each unit of study.  This makes it so easy to adjust my teaching strategies, as needed, to meet students’ needs. I really like the curriculum!

We recently purchased a large quantity of Pre-K learning systems for Workforce Solutions Northeast Texas. From the initial inquiry through purchase, shipment, and training their service and customer support has been top notch. Our providers are very pleased with the curriculum and state it is easy to use and they love it.

I love the program! It has great ideas and sometimes I take off with it and add more to the activities. It incorporates all the subjects and the students love it! The phonological awareness is amazing and my students have honestly grown more than ever!

I wanted to take a few minutes and thank you for developing not only an impressive curriculum for childcare and Head Start programs, but for bridging the gap for family engagement with Dilly’s Tree House.  As you know our industry has changed dramatically and we all need to keep up with if not ahead of the changes.  You have done just that with the Investigator Club curriculum and Dilly’s Tree House.  I can’t wait to see what you have around the corner for us.

The Investigator Club has proven to be a great curriculum for my inclusive preschool classroom. I love how it covers all subject areas from math to science to literacy to social skills. I am able to simply open up the curriculum and have everything I need without having to search around for more ideas. This is my first year using InvestiGator Club, and I am very impressed with the content, themes, materials, and resources in this curriculum. I’m excited to use it for the years to come!

The InvestiGator Club is a wonderful, engaging, and exciting early childhood curriculum. It makes my job as an educator fun and rewarding to listen to my students’ excitement over what they are learning. The children have made tremendous gains this year.

The InvestiGator Club Early Childhood Curriculum is grounded in sound child development principles that are fully aligned with Head Start child development principles. The foundation for the curriculum is built upon the belief that children learn best by interacting in a developmentally appropriate and challenging environment through relationships with teachers. The foundational principles fully align with the Head Start development principles of orderly and sequential development and the influence of a child’s social and cultural context.
