At the dinosaur dig site, Emek and Luna had 56 bones to pack safely for a trip. Each protective crate could hold exactly 8 bones. Luna grouped the bones in sets of 8 while Emek counted the groups. They found 7 equal groups, so they needed 7 crates. To check, Emek counted 7 groups of 8 and got 56. No bones were left over. They carefully closed all 7 crates, ready for the journey.

Hint
Think about splitting 56 bones into equal groups of 8.
Emek and Luna have 56 bones, and each crate holds 8 bones. Which operation should they use to find the number of crates needed?
56 + 856 - 856 divided by 856 times 8Correct! Division finds how many groups of 8 are in 56.
Try again. Choose the operation that separates 56 bones into equal groups of 8.
Next🎉 Congrats! You got this question!
Hint
First find how many bones are in 5 crates, then compare that amount with 56.
Emek and Luna packed 5 of their 7 crates with 8 bones in each crate. How many of the 56 bones were still left to pack?
Correct! After filling 5 crates, 16 bones were left to pack.
Try again. Find the number of bones in 5 groups of 8, then subtract from 56.
Next🎉 Congrats! You got this question!
Hint
Find 6 groups of 8 and compare the result with 56.
Another helper says that 6 crates would be enough for all 56 bones. Each crate holds exactly 8 bones. Which statement correctly checks the helper's idea?
6 crates hold 48 bones, so 8 bones would still need a crate.6 crates hold 56 bones, so no bones would be left.6 crates hold 54 bones, so 2 bones would be left.6 crates hold 64 bones, so there would be extra space.Correct! Six crates hold only 48 bones, leaving 8 bones to pack.
Try again. Calculate 6 times 8 and compare it with the 56 bones.
