2-min Fluency Warm-up — Quick 2D review from last week!
Sides on a square:
Vertices on a triangle:
Sides on a hexagon:
A 5-sided polygon is a:
2D shapes are flat — they live on paper. 3D shapes are solid — you can hold them! Meet the six solids:
Cube
Rectangular Prism
Sphere
Cone
Cylinder
Pyramid
Write the name of each solid. Use the word bank: cube, sphere, cone, cylinder, pyramid.
Number Talk — Explain WITHOUT touching or counting.
A sphere can roll but a cube cannot. What about their shapes makes this true?
My thinking:
Is a circle the same as a sphere? Explain the difference between flat and solid.
My thinking:
Read carefully. Think about what is happening.
Theo is packing a box with blocks. He has 4 cubes, 3 cylinders, and 2 cones. How many solids that can ROLL does he have? (Hint: which of these solids have a curved surface?)
My thinking:
rolling solids
