An engaging 15 question math activity for using the distance formula. Students must crack the code in each section to reveal additional questions requiring their understanding of the distance formula given endpoints and graphs. Each question will reveal a part to a code that students will use a corresponding wheel to crack the code and open up new sections.

Answers include integers and decimals and students will be required to round their answers to the nearest tenth.

This activity is for use with Google Sheets only. It is self-checking and includes automatic grading.

How this activity works: When students open the activity, they will see questions 1 - 5. As they answer the questions, parts to the code they need to crack will begin to appear. Students will use the designated wheel to match letters/numbers with letters/numbers. After they have answered question 1 - 5 and attempted to crack the code, the activity will let students know which answers are right (green) or wrong (red). Students can then correct any incorrect answers. Once they have successfully completed a section, the next section will appear.

This activity is self-grading however will only show updated scores when sections are completed. This means, students will not know which answers are correct/incorrect by their score changing until they have answered everything in a section (just like the green/red answer spaces).

Question Breakdown:

• 1 - 5: finding the length of a segment given two endpoints
• 6 - 10: finding the length of a segment graphed on the coordinate plane
• 11 - 15: finding distance between different "landmarks" plotted on one coordinate plane

This activity requires no prep once added to your Google Drive and includes a student version and an answer key.
