Welcome Message

We are so excited to partner with you to support science teaching for grades 2 to 5. Speak Agent is a digital supplemental program for all learners, including multilingual learners (ELLs). It integrates your TEKS-aligned science content together with research-based activities across all six communication modes so that students acquire the language and concepts they need to succeed. One unique aspect of Speak Agent is that it has been tailored specifically for the SISD curriculum. That means you will find the digital resources line up with your IFDs.
