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.

    Mo is correct because 2400 cm is 24m and 22m is smaller than 24m.Alex is incorrect because 1600 cm is 16m and 16m are smaller than 20m.

    Penguin 5+5+10+10=20
    Rino 12+12+4+4=32
    Snack 6+6+3+3=18
    Rino because it has the primter of 32.
    Snayk because it has the primter of 18.
    Mo because the walrus is 19 primter and the panda is 22 primter.

    Silver:
    The Rhino is first because it has 32
    Second is the penguin because it has 30.
    Third is the panda and the Giraffe because they both have 24.
    Last is the snake with 18.Mo is correct because if you convert 22m it is 2200cm and 2400 cm is greater than 2200cm so Mo is correct.
    Alex is wrong because she forgot to convert 20m, that is 2000cm and 1600 is lesser than 2000cm so Alex is wrong.

    Silver:
    The big one is rhino.
    The small one is snake.
    Gold:
    Mo is correct because walrus enclosure perimeter is 22m and panda enclosure perimeter is 2400cm which means 24m. so walrus enclosure perimeter is smaller than the panda enclosure perimeter .

    SILVER:
    Rhio animal has the enclosre with the longest perimeter.
    Snake animal has the enclosuer with the shortest perimeater.
    GOLD:
    Mo is correct
    because,
    the walrus enclusure perimeter is 22m
    the panda enclusure perimeter is 2400cm = 24m
    so walrus enclusure perimetre is smaller.

    Silver:
    The Rhino Enclosure is the animal with the biggest perimeter.
    The Snake Enclosure is the animal with the smallest perimeter.
    Gold:
    Mo is correct because for the panda is 7+5+7+5= 24 and the walrus is 8+3+8+3=22. The walrus is 22 metres is the same as 2200cm and the panda is 24 metres which is the same as 2400cm. Mo said that the walrus’s perimeter is smaller than the panda’s perimeter which is correct because 22 is smaller than 24.

    Mo is correct. I know this because there is 100 centimeters in a meter, and there are 20 meters in 2,000 and 400 is higher than 200. That is how I got my answer.

    Mo is correct I know this because the panda is 7+5+7+5=24 but the walrus seems to have more because 4+8+4+8=32 so need mo is correct.

    Mo is right because the walrus enclosure is 22m which is smaller than the perimeter of the panda.

  25. Sheik A.

    Panda.35 because 5×7=35
    Giraffe.27 because 9×3=27

    Dino.48 because 12×4=48
    Snak.18 because 3×6=18
    Snake has the shortest primitive
    Rino has the longest premier

    The animal with the shortest perimeter is the turtle.The perimeter of the turtle is 3+3+3+3=12.
    Gold
    Mo is correct.I know this because 22m is equivalent to 2200cm.1 meter is 100cm.2400cm is equivalent to 24m .2200 is smaller than 2400.

  27. Osas O.

    16 meters is less than 24 meters

  28. Osas O.

    16 meters is less than 24 meters.

    1. Osas O.

      3+5+3+5 = 16 squares
      2+10+2+10 = 24 squares
      7+3+7+3= 20 squares
      5+5+5+5 = 20 squares
      2+3+2+3 = 10 squares
      6+3+6+3 = 18 squares
      10+1+10+1 = 22 squares

  29. Osas O.

    The perimeter for the panda enclosure is 10+5+5+10 = 20 squares
    The perimeter for the giraffe enclosure is 8+8+7+1 = 27 squares
    The perimeter for the penguin enclosure is 20+20+10+10 = 50 squares
    The perimeter for the rhino enclosure is 12+12+12+12 = 48 squares
    The perimeter for the snake enclosure is 6+6+4+2 = 18 squares
    The perimeter for the penguin enclosure is the largest with 50 squares and the snake enclosure is the smallest with 18 squares.
    Gold
    One meter is 100 centimeters so 2400cm is 24 meters. 1 meter is 1 square.
    This makes 1600cm 16 meters, which is 16 squares.

    I will do this in my book.(I don’t have squared paper)
