Introduce the Ellipsis Symbol ( ••• ) in Bar Models 3-39
Use an ellipsis as a shortcut when drawing 5 or more groups. What's 5x4? Instead of drawing all 5 groups, draw groups 1 and 2 with 4 in each group. Draw a bar with "•••" to show the pattern of 4s continues, then draw the last 4 – group 5. Which groups does the "•••" represent? The ellipsis represents groups 3 and 4.
