Rainbow collaborated with the team at Ellevation on the development of 150+ ELLevation Math Online Primers (short lessons) that English Language Learners complete before math class in order to learn key academic vocabulary of a standards-aligned math unit.
These primers for Grades 3–5 were created in the context of mathematical concepts to solve a real-world problem relevant to a pre/adolescent audience.
In addition to content development, Rainbow oversaw the creation of 4,000+ illustrations and animation, and handled the production of audio files.
