To teach mathematics in the 21st century, and more specifically to teach early algebra, the teacher should bring to the classroom a particular cluster of skills, understandings and knowledge. Early algebra is crucial for students’ success in higher mathematics. While a written curriculum is needed for teaching, a teacher’s beliefs and knowledge are also important determiners of the algebra content taught in the classroom. In this cross-cultural study, we examine the similarities and differences found in two recent and concurrent mixed methods research projects in both Australia and Nigeria. The two research studies showed teachers’ beliefs had a meaningful influence on the teachers’ practice.
