Year 4 Maths Challenge Spring 1

Mrs Khaliq

Here is a plan for a new zoo that will be opening in 2023.

Bronze

Calculate the perimeter for the following animal enclosures in squares and ensure you show the calculations.

Example:

The koala enclosure perimeter is 3 +8+3+8=22 squares

What is the perimeter of these enclosures?

  1. Panda
  2. Giraffe
  3. Penguins
  4. Rhino
  5. Snake

Silver

Which animal has the enclosure with the longest perimeter?

Which animal has the enclosure with the shortest perimeter?

Gold

Each square on the plan is equivalent to 1 metre.

Platinum

You have been asked to design a new zoo for the community! You have been given specific building requirements to follow. Make sure you use squared paper and a ruler!

Each enclosure has 4 sides and here are the measurements in squares. Calculate the perimeter for the animals and draw the enclosures ensuring you label them.

You need to plan out the second row of enclosures and write your chosen perimeters and calculations.

Bring your completed zoos with perimeter measurements into school.

    The Zebra has the longest perimeter.
    The tortoise has the shortest perimeter
    Gold
    Parrot-1600cm=16m
    Walrus-22m
    Panda-400m=24cm
    Mo is correct because the Panda enclosure is bigger than the walrus. Alex is incorrect because the parrot is smaller.

    Silver:
    Rhino=32 cm longest perimeter
    Snack =18 cm shortest perimeter
    Gold:
    Mo is correct because 2400 cm it’s 24m and 22m smaller than 24m.

      Silver
      Gorilla with the perimeter of 16 is the longest perimeter.
      how ever the shortest perimeter belongs to the turtel

    The Rhino has the biggest perimeter because it has the biggest number all together.
    The snake has the shortest perimeter because it has the smallest number all together .

    GOLD

    Mo is correct . Because Walrus enclosure perimeter is 22m and Panda enclosure perimeter is 24 meter . 24 m = 2400 cm.

    silver the longest animals perimenter is the rhino
    the animal with the shortest perimenter is the snake
    gold i ageer with mo because it not meter it is cm it is not in 100
