This Excel spreadsheet is for whole class discussion and/or individual use. The presenter (or student) can change the titles of things being compared and then use buttons to easily change the ratio. As the ratio is modified, the Tape Diagram is automatically created!
From there, you can use the built in slider to change the factor for each box in the tape diagram. As you do this the totals are automatically calculated and a table is shown!
Automatic Tape Diagram and Table with only a few clicks of the mouse.
