Connections between using a number line and place value. The analogy between billion and trillion really reinforced the concept of place value and the base ten values. Visuals and models are difficult for students to handle unless they have had prior exposure. Never make assumptions with kids. I have found that even students at the intermediate level have difficulties reading visuals and knowing the parts or components. I really had to reinforce how to read visuals and looking at titles, captions, arrows etc. Some students have spatial visual orientation challenges. I had students with L.D. in math so the spatial orientation was a challenge (e.g., writing numbers vertically versus horizontally).
