It’s well known among educators that complex and abstract topics can be understood more easily (especially by younger students) when concepts are introduced visually. Visuals not only improve a student’s ability to understand how something works, but also help with retention. Furthermore, by seeing the “whole” of something, children are better able to understand the parts. Even more importantly, research shows that 3D-animated models are able to represent information in the most efficient m

Attention Getting Question: Have you ever tried to multiply a four-digit number? Introduction: Multiplying helps us to determine how many total objects are represented when we have multiple groups of the same size. For instance, we know that when we multiply four times six, our answer will be twenty-four. We can think of this as having four groups of six objects or six groups of four objects. Being able to switch the factors and still get the same product or answer in a multiplication equation i

Essential Question: Have you ever tried to multiply two two-digit numbers? Introduction: Multiplying helps us to determine how many total objects are represented when we have multiple groups of the same size. For instance, we know that when we multiply three times eight, our answer will be twenty-four. We can think of this as having three groups of eight objects or eight groups of three objects. Either way, the result will be twenty-four total objects. Being able to switch the factors and still
