Doubling & 3D Shapes — for every learner 💖
What is doubling?
Doubling means adding a number to itself!
Double 2 = 4
🍎🍎 → 🍎🍎🍎🍎
Double 5 = 10
⭐⭐⭐⭐⭐ → ⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐
Double 10 = 20
10 + 10 = 20
Double 7 = 14
7 + 7 = 14
What is double this number?

What are vertices?
Vertices are the corners or points where edges meet!
📦
Cube
Vertices: 8 (corners)
Edges: 12 (lines)
Faces: 6 (flat sides)
Like: A dice, a box
🔺
Pyramid
Vertices: 5 (corners)
Edges: 8 (lines)
Faces: 5 (flat sides)
Like: Egyptian pyramids

Triangular Prism
Vertices: 6 (corners)
Edges: 9 (lines)
Faces: 5 (flat sides)
