We have a new magnetic building set in the house and I am ridiculously excited about it.
It’s awesome. Seriously.
Want to hear all the reasons why?
- The shapes are fun to play with and very creative.
- You can build modern abstract sculptures in all kinds of fun configurations.
- You can explore magnetic properties and build in ways that are not possible with regular building blocks. In fact, because of the lightweight cardboard, you can build in ways that are not possible even with other magnetic building sets.
- All we used were cardboard, some glue, and a coil of magnetic tape. Even the paint is optional as the magnetic shapes look awesome with or without it.
- This activity does a great job of exposing your kids to STEM. Sylvan Learning believes it’s important for kids to be exposed to STEM education because they are at the prime age for exposure, retention, and application. Incorporating STEM into fun activities like this magnetic building kit is a great way to start introducing your kids to STEM!
I know you’re going to want to make a set for yourselves, so I’ll show you how, with step-by-step instructions.
Make Your Own Magnetic Building Set with Cardboard
Children can explore magnetic properties and engineering with hands on learning and open-ended exploration. Building cool contraptions in an open-ended way helps kids become creative thinkers and problem solvers, which is vital to their future success and even the future of our world. If you are looking for fun ways your kids can learn engineering from the experts, Sylvan Learning offers a STEM focused program, the Sylvan EDGE. EDGE provide hands-on learning opportunities in classes focused on Robotics, Engineering, Coding, and Math Edge. These programs give students the confidence and skills to be successful in the future global workforce.
*Save those boxes! Or stop by a store that’ll let you cart away their boxes. I went to an ABC Store for mine and found that the inserts to the liquor boxes work especially well for making these cardboard shapes as they are plain (no markings), not too thick, and somewhat pre-scored.
- Cut your 3D cardboard shapes
Use a utility knife to cut cardboard strips against the grain. (You want the corrugation lines to run across the width of the cardboard strip.) I cut my cardboard pieces about 2 inches by 10-12 inches.
Fold your cardboard strip into your desired shape, such as a triangle, square, rectangle, or trapezoid.
- Glue your shapes together
Now that you have your fold marks, run a line of hot glue along one edge of the cardboard strip, then fold the cardboard back into shape, holding the two ends together for 30 seconds or so until the glue hardens.
Repeat with more cardboard strips and shapes. Make as many as you like! You can experiment with different shapes and sizes, too.
- Add your magnetic tape
Apply your magnetic tape to the cardboard shapes. To do so, cut a section of the magnetic tape (perhaps 1-2 inches long depending on the size of the cardboard piece you’re applying it to). Bend the magnetic tape against its natural curvature to flatten it out, then remove the paper backing, and press the adhesive side to one side of the cardboard shape. You can add the magnet strips to one or all sides of the cardboard shapes as desired.
Note :: If you know you want your magnetic building set to be colored, I suggest painting the cardboard shapes first, before applying the tape. We were figuring things out as we went and did this a little backwards.
- Try them out!
Now, try out your new magnetic building blocks!
We especially liked how we could build at an angle instead of just vertically. Because of the lightweight nature of the cardboard and the 3D shapes, we could build quite differently with this magnetic building set than with our magnetic tiles.
Don’t you just love how sculptural this looks?! I actually really like the plain cardboard look of these, but we voted to paint our shapes. The painted ones look even better!
- Paint your cardboard building blocks
We used tempera paint, but acrylics or BioColors would work too.
We had to be careful to paint around the magnets, which is why I recommend you paint your shapes first and then apply the magnets.
Once the paint on your magnetic building blocks dries, build with them!
See what you can do with these lightweight, 3D, magnetic building blocks? So much!
Are you ready to build your own ridiculously cool magnetic building set now? I highly recommend you give this a try!
