Our intervention for improving children's understanding of equivalence (ICUE)

Children's understanding of math equivalence in elementary school predicts their algebra readiness in middle school. Unfortunately, most children struggle to understand this foundational concept. We designed a supplemental intervention to improve children's understanding of math equivalence, and it has been shown to work in a small, randomized experiment and in a larger efficacy study with the help of WestEd. Download the materials and watch videos explaining each of the four components of the ICUE intervention on the website!

The ICUE intervention was featured in a "What Would You Fight For?" Commercial on NBC!
