What mathematical operation does the teacher model after recalling prior knowledge of addition?

Modeling with cubes effectively illustrates the concept of addition in a tangible way. This method allows students to visualize and physically manipulate objects to understand how numbers combine to form sums. By using cubes, a teacher can provide a concrete representation of addition, where students can group the cubes and count them to find the total. This hands-on experience reinforces the connection between the abstract operation of addition and its practical application, making it easier for students to grasp the concept.

In addition, employing cubes in modeling also helps to engage various learning styles, enabling students who benefit from visual and kinesthetic learning to better understand addition. This approach is particularly useful when recalling prior knowledge, as it connects new information to previously learned concepts, deepening students' comprehension and retention of addition.
