🏠 Part 1: Planning Your Doghouse

1. Draw a simple plan of your doghouse. Include measurements in centimetres.

2. What measurements do you need to plan before building? Check all that apply:

Length of the floor

Width of the floor

Height of the walls

Size of the door

Colour of the paint

📏 Part 2: Measuring and Calculating

3. Your doghouse floor is 80 cm long and 60 cm wide. What is the perimeter of the floor?

Perimeter = length + width + length + width

Answer: _______ cm

4. You need these pieces of wood for the walls:

• Front wall: 80 cm

• Back wall: 80 cm

• Left wall: 60 cm

• Right wall: 60 cm

What is the total length of wood needed for all walls?

Total length: _______ cm = _______ metres and _______ cm

5. If you have a plank that is 3 metres long, how much will be left over after cutting the wall pieces?

3 metres = _______ cm

Wood left over: _______ cm

📐 Part 3: Angles in Construction

6. Circle the corners that show right angles in a doghouse:

Where the wall meets the floor

Where two walls meet at a corner

The slope of the roof

Where the door frame meets the wall

7. Draw and label three right angles you would find in your doghouse:

8. A right angle is:

A very sharp corner

A square corner like the corner of a book

A curved corner

Any corner that looks neat

🔨 Part 4: Problem Solving

9. The door opening is 30 cm wide. If the front wall is 80 cm long, how much wall space is left on either side of the door if it's centred?

Wall space on each side: _______ cm

10. Fill in the missing measurements:

If the doghouse is 80 cm long and you've already cut a piece that is 35 cm, you need another piece that is _______ cm to complete the length.

80 - 35 = _______

11. Match the building task with the correct maths operation:

1. Finding total wood needed

2. Finding leftover materials

3. Checking if pieces fit together

4. Finding perimeter of floor

A. Addition

B. Subtraction

C. Measuring

D. Addition

🤔 Part 5: Reflection

12. Why is it important to measure accurately before building?

13. Describe one time when you used addition and one time when you used subtraction in planning your doghouse:

Addition:

Subtraction:

14. What would happen if you didn't use right angles when building the corners of your doghouse?
