What action should Mr. Hernandez take for a child struggling with a new math concept?

Making the new material concrete is an effective approach for aiding a child who is struggling with a new math concept. Concrete learning involves using physical objects, visuals, or hands-on activities to help students understand abstract ideas. By providing tangible examples, Mr. Hernandez can facilitate the child's comprehension of the new math concept. This method not only helps in clarifying the material but also serves to engage the student, making learning more relatable and accessible.

By activating prior knowledge or setting up an intervention, while beneficial, may not directly address the immediate struggle with the new concept as effectively as concretizing the material. Simply referring the child for remediation also might not provide the immediate support needed in the classroom context. Therefore, making the new material concrete is a targeted strategy to support the student’s learning process and bridge the gap in understanding.
