The purpose of this study is to investigate neurocognitive mechanisms underlying response to intervention aimed at enhancing, and remediating weaknesses in, numerical skills in children, including those with mathematical learning disabilities (MLD).~To achieve this goal, investigators will use a theoretically-motivated integrated symbolic/non-symbolic (iSNS) intervention with a randomized controlled design to enhance cross-format mapping between symbolic and nonsymbolic representations of quantities. The investigators will develop innovative computational models to investigate individual differences in latent cognitive processes and brain plasticity that contribute to learning, long-term retention, and transfer in children.~The investigators will assess performance in several areas and investigate cognitive and neural mechanisms that support numerical skill acquisition in children with differing levels of math learning abilities.
