ab: Summary: Three studies explore arithmetic tasks that support both
substitutive and basic relational meanings for the equals sign. The
duality of meanings enabled children to engage meaningfully and
purposefully with the structural properties of arithmetic statements in
novel ways. Some, but not all, children were successful at the adapted
task and were able to connect making substitutions of notation with
their existing mental calculation strategies. (ERIC)
