Abstract	One of the most difficult topics to teach in geometry is the concept of proof. This article describes ProofBlocks as an innovative approach to helping students develop proficiency in proof. ProofBlocks is an intuitive approach to teaching proof that makes proof accessible to students without sacrificing the rigor of traditional approaches. When using ProofBlocks, students find it natural to work from both ends of their attempted proof, breaking it into smaller pieces and searching for the information they need to make logical connections. ProofBlocks is an inherently visual approach that lends itself to the use of manipulatives, thereby addressing the needs of visual and kinesthetic learners, who are often neglected when other forms of proof are taught. This technique provides a wide range of benefits over more traditional forms of proof as taught in the high school classroom. It separates geometric knowledge from logical reasoning, providing a more manageable structure within which students can explore geometry while developing their proof intuition. (Contains 8 figures.)
