ab: Summary: A teaching intervention study was conducted with sixth grade
students to explore the interconnections between students’ growing
understanding of arithmetic expressions and beginning algebra. Three
groups of students were chosen, with two groups receiving instruction
in arithmetic and algebra, and one group in algebra without arithmetic.
Students of the groups that learnt arithmetic developed a strong
understanding of the concept of term and applied it to reason about
equal expressions. They performed better at some questions in algebra,
especially those that required a sense of the structure and meaning of
the expression.
