5 building activities for practising high school math

Article

Math plays an essential role when it comes to construction. All building projects require using principles of geometry, arithmetic, and trigonometry. To help your high schooler practise math using a more hands-on approach, we’ve rounded up five activities they can do right from home.

Make a mini greenhouse

Mini greenhouses are beautiful enclosures that you can use to grow seedlings or keep delicate plants warm. Here’s how to make one from scratch using some old wooden picture frames with glass panes.

Materials:

  • large picture frames (30 x 40 cm)
  • medium picture frames (30 x 24 cm)
  • small picture frames (18 x 13 cm)
  • Wood glue
  • hinges and their screws
  • small angle brackets and their screws
  • Acrylic paint
  • A screwdriver
  • Soil
  • Seedlings

Instructions:

  • Set the small panes of glass inside the picture frames and apply wood glue to hold them in place
  • Arrange the 4 large and medium frames to form a rectangular prism
  • Attach the angle brackets to hold the prism together
  • Using the hinges, attach the small frames in pairs along the shorter edge
  • Glue the three pairs together using the wood glue to make the roof
  • Place the roof on the rectangular prism
  • Paint your mini greenhouse the colour of your choice
  • Add the soil
  • Plant the seedlings
  • Etc.

This activity is ideal for understanding angles and the characteristics of a rectangular prism.

Build a bookshelf

Why build a conventional bookshelf with parallel shelves when you could create a far more interesting design with just four wooden crates? This activity is all about arranging solids in space. Here’s what your teen will need to do:

  • Find a creative way to stack the crates
  • Apply wood glue to hold the crates together
  • Paint the finished piece however they like

Tips and tools

Before your teen starts building their bookshelf, suggest making a construction drawing. This will help them avoid missing any steps and make sure they have all the materials at hand.

Make a wall-mounted coat rack

All you really need to make a wall-mounted coat rack are a few hooks or knobs and something to attach them to. Have your teen come up with their own design, or suggest materials they could use:

  • A skateboard
  • A thick piece of bark
  • A wooden pallet
  • Etc.

Tips and tools

Ask your child to calculate the area of the backing they choose (e.g., a skateboard) so that they can space the hooks or knobs evenly. This will ensure their coat rack is visually balanced.

Build a birdhouse

While it’s possible to build a birdhouse entirely out of wood, it’s just as effective, not to mention much easier, to use an empty milk carton.

Materials:

  • A clean, empty milk carton
  • Craft sticks
  • A twig
  • String
  • Scissors
  • Paint
  • Hot glue

Instructions:

  • On one side of the milk carton, cut out a circle 3 cm in diameter
  • Glue the twig beneath the circular opening to create a perch
  • Glue the craft sticks to the carton so it’s completely covered
  • Paint and decorate your new birdhouse
  • Fill it with seeds

Your teen will be able to use their math skills at various points during this activity:

  • Calculating the circumference of the circular opening
  • Estimating the number of craft sticks needed to cover the milk carton
  • Measuring the length of the craft sticks
  • Etc.

Make a wooden puzzle

The neat thing about wooden cube puzzles is that they’re really six puzzles in one. They make a great gift for younger siblings!

Materials:

  • A 2″ x 2″ x 8′ piece of lumber
  • A saw
  • Felt-tip pens or paint

Instructions:

  • Cut the lumber into 16 identical cubes
  • Arrange the cubes in a 4 x 4 square
  • Draw or paint a pattern over the entire surface of the square
  • Flip the cubes so the next side is facing up
  • Repeat the previous two steps until all sides of each cube have been decorated

Be careful!

Your child will need to use a mitre saw or bow saw to cut the lumber into cubes. Make sure they’re supervised by a responsible adult.
