## Reflection: Checks for Understanding Finding Equivalent Ratios - Section 4: Exit Ticket

In checking students' exit tickets, I noticed a few common mistakes:

• not labeling the tape diagram (red and blue); Labeling the diagram will help prevent using the wrong number in their work.
• dividing incorrectly to find the value of each square
• not verifying if their final answer makes sense; The new ratio of red to blue should be equivalent to 2 to 3.
