Our Proprietary Curriculum Framework

Our curriculum understands the different parts that make up a whole math learner. By using our proprietary framework C.R.A.F.T. ™, we can see each math learner as an individual and meet their specific needs. 

C.R.A.F.T. Proprietary Curriculum Trapezium Logo

  • Counting

    Just as phonics and phonemic awareness are central to the Science of Reading, counting is central to the Science of Math. Counting by different intervals forwards and backwards and counting by mixed numbers lays the foundation for mental math fluency with addition, subtraction, multiplication and division. 

  • Reasoning

    Developing problem solving skills is essential to being a strong math learner. In Math Club students use the critical thinking necessary to pull pertinent information, solve equations, and consider how answers make sense in the context of a problem and the real world. 

  • Automaticity

    Trapezium has developed incremental activities beginning in kindergarten that support full automaticity in addition, subtraction, multiplication and division facts by the end of 3rd grade. 

  • Fluency

    We support students in developing a mental map of numbers so that they can understand, relate, and connect numbers. Additionally, students are guided to transfer what they know about numbers to time, money and measurement. 

  • Tenacity

    Cultivating tenacity is essential to supporting a strong and confident math learner. Through different games and challenges we support students in developing the ability to approach hard math with a willingness to fail and keep trying. We want students to know they are capable of doing hard math!
