My preschooler is very into building, blocks, lego, bricks – anything with an engineering or maths twist to it. And I love seeing him learn through his play. So I’ve introduced the concept of ‘symmetry’ to him. He doesn’t know he’s learning a maths concept. But he intuitively gets it. So I set him challenges to mirror a duplo design I’ve done, or make a symmetrical shape like the one above. It’s basic at this stage, but it’s great to get them really noticing what they’re doing and thinking about symmetry and reflections.
