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 rhino enclosure has the longest perimeter which is 32 squares and the snake enclosure has the shortest perimeter which is 18 squares.
    Gold
    Mo is correct I know that 2400cm is equivalent to 24cm so 24cm is bigger than 22cm so therefore Mo is correct and Alex is wrong.

    Mo is correct because 2400 cm it is equal to 24 cm and 24 cm is larger than 22 cm.

  3. Madeeha T.

    Panda :24 because 5+5=10 and 7+7=14 so 10 +14 = 24.
    Giraffe: 24 because 9+9=18 and 3+3=6 so 18+6=24
    Penguins: 30 because 10+10=20and 5+5=10 so 20+10=30.
    Rhino: 32 because 4+4=8 and 12+12=24 so 8+24=32
    Snake: 18 because 3+3=6 and 6+6=12 so 12+6=18
    Silver
    The rhino has more enclosure because the perimeter is 32
    The snake has less enclosure because the perimeter is 18.
