We design evidence-based programs, innovative tools, and professional learning that make student thinking visible, giving educators actionable insights that save time and strengthen instruction. For more than 25 years, PowerMyLearning has partnered with schools and districts nationwide, especially those serving multilingual learners and students from historically underserved communities. MathVoice™ is our evidence-based math practice tool for grades K–3. Through collaborative, play-based activities, students engage in meaningful math conversations, build mastery of grade-level content, and develop the confidence to see themselves as mathematicians. By moving beyond right or wrong answers, MathVoice helps teachers better understand student reasoning, identify misconceptions, and provide more targeted support. Our programs are backed by a robust evidence base, including a +10 percentage point gain in math achievement for K–5 students. To learn more, visit PowerMyLearning.org.
