In their latest maths adventure, the Reception children dived into the concept of doubling with a hands-on, prehistoric twist. The classroom was buzzing with excitement as the children constructed a tall wall to hide a small group of dinosaurs on the other side. To sharpen their "subitising" skills—the ability to recognize a quantity without counting—the children were invited to take a "quick look" over the wall before the dinosaurs were hidden once more. After identifying the initial number of dinosaurs they saw, the challenge began: they had to calculate what that number would be if it were doubled. This playful activity turned an abstract mathematical operation into a visual game, helping the children understand that doubling is simply adding the same amount again to create a larger total.
