Jacobian Series — Empowering every learner, one workbook at a time. Available across West Africa and Internationally
Mathematics for every level
ABOUT JACOBIAN SERIES
Jacobian Series is a premier educational publishing initiative dedicated to producing high-quality, curriculum-aligned mathematics workbooks for students at every level, from foundational West African examinations to the most competitive international qualifications.
Rooted in a passion for mathematical excellence and driven by a commitment to equity in education, Jacobian Series bridges the gap between classroom instruction and examination success.
Founded and led by Godfred N.A. Welbeck, a certified IB Diploma Programme teacher with extensive international classroom experience, Jacobian Series is shaped by years of teaching students with different needs, ambitions, and starting points.
The series serves the average learner battling self-doubt in mathematics as thoughtfully as the high-achieving student aiming for distinction in IBDP Higher Level examinations. It spans national West African curricula and globally recognised international programmes, making it a versatile, indispensable resource.
VISION & MISSION
To become the most trusted and widely used mathematics workbook series across West Africa and the international education community: a beacon of academic empowerment that transforms every student's relationship with mathematics, regardless of background, ability, or location.
To design, author, and publish rigorous yet accessible mathematics workbooks aligned with the highest national and international examination standards; equip students with understanding, fluency, and confidence; support teachers with structured classroom resources; and champion mathematical literacy as a gateway to opportunity, especially for under-served learners.
