This video shows how we can compare numbers, if the unit of length are the same, to order by length.

A shark is $6$6 m long, a boat is $19$19 m long, a dolphin is $3$3 m long, a ship is $25$25 m long and a whale is $14$14 m long.

Choose the list that puts the items you may find in the water from shortest to longest.

Dolphin, Shark, Whale, Boat, Ship

AWhale, Dolphin, Ship, Boat, Shark

Remember!

As long as the units are the same, you can compare and order lengths in the same way as we compare numbers.

Use scaled instruments to measure and compare lengths, masses, capacities and temperatures
