Our 4 Valentine's Day Crafts for a fun DIY Valentine's

  1. Binary Hearts​​​
  2. LED Pop-up Valentine's cards
  3. Valentine's heart boxes
  4. Valentine's heart Lego puzzles

1. Learn binary code with our binary hearts

Create a geeky Valentine’s craft decoration (or necklace?) as you learn how to speak the language of computers: binary. This activity has a lot of learning, from learning binary to the fine motor movements of stringing on each bead.

2. DIY 3D Cards: Valentine’s cards with paper circuits

I absolutely adore these DIY Valentine’s cards. Our free downloadable template has two options, a regular popup heart that has an LED, or a beating heart, which is also a popup heart, but instead of a single ON/OFF pressure switch it has a sliding switch that allows the LED to “beat”. It might seem daunting, but our videos will help you master paper circuits of all types, including this one!

3. Learn how to make a paper box: Valentine’s heart boxes

I love an engineering challenge, and this one has a direct use. Not to say that spaghetti bridges aren’t fantastic engineering challenges – they are. But having the result have to fit specific needs that will actually be used can be a huge motivator for kids. In this Valentine’s day craft, they will engineer a heart-shaped box to gift candy in!

4. Puzzles for kids: Heart shaped Lego puzzles

This is a new spin on DIY Valentine’s – heart-shaped Lego puzzles. In this set of six Lego puzzles, kids will try to recreate the image with their own building blocks – a sort of spin on tangrams. Kids will enjoy trying to create a Valentine’s day photo frame from their box of bricks!
