Ratio tables

Target: Complete a row of a ratio table with one factor.

Language target: Explain a row as “times” the first row.

Likely miss: Students complete a table by adding down a column instead of multiplying a whole row.

Ask: Does that factor work in both columns?

If you see it: Have the student underline both products and name the shared factor before computing.

Evidence to listen for: A new row uses one factor for both columns.

Next: Return to a double number line if addition appears. Otherwise compare two ratios.
