Summary: Although it is generally recognized that algebra has a role to play in the early mathematics curriculum, the issue of whether elementary school children are developmentally ready to use algebraic notation and to understand the syntactical rules of using algebra for solving equations is still a matter of debate. We examine, at the end of a third to fifthgrade (8 to 11 years) intervention using a functional approach to algebra, how students try to solve word problems they represent as equations containing the same single variable on each side of the equals sign.
