Inside the fossil tent, Emek and Luna prepared discoveries for a museum display. Their table showed that Zone A had 7 teeth, 4 claws, and 3 shells. Zone B had 5 teeth, 6 claws, and 2 shells. Zone C had 8 teeth, 5 claws, and 1 shell. They compared the data across all three zones. Teeth appeared most often, while shells appeared least often. Emek and Luna gave the common teeth a large display tray and placed the rarer shells in a special case.

Hint
Compare the number of teeth and claws in each zone.
Which zone had more claws than teeth?
Zone AZone BZone CAll three zonesCorrect! Zone B had 6 claws and 5 teeth, so it had more claws than teeth.
Try again. Check the teeth and claws in each zone one at a time.
Next🎉 Congrats! You got this question!
Hint
Add the teeth from all three zones: 7, 5, and 8.
How many teeth did Emek and Luna find altogether in Zones A, B, and C?
Correct! They found 20 teeth altogether.
Try again. Add the number of teeth from each of the three zones.
Next🎉 Congrats! You got this question!
Hint
Add the shells from the three zones, then compare that total with 20 teeth.
Emek and Luna found 20 teeth altogether. Which comparison best explains why they placed the shells in a special case as the rarer type?
There were 6 shells, which is fewer than the 20 teeth.There were 14 shells, which is fewer than the 20 teeth.There were 20 shells, the same number as teeth.There were 21 shells, which is more than the 20 teeth.Correct! There were only 6 shells compared with 20 teeth.
Try again. Add 3, 2, and 1 to find the total number of shells.
