Across
- 1. A pyramid with a triangular base. Picture a pyramid-shaped hat with a triangular bottom.
- 3. A pyramid with a rectangular base. Picture a pyramid-shaped house with a rectangular floor.
- 4. The total area of all the sides of a 3D shape except the top and bottom. It's like wrapping a present without the top and bottom flaps.
- 7. Area The sum of all the areas of a 3D shape's faces. It's like adding up all the wrapping paper on a gift.
- 9. When a shape spins around an axis, like a carousel going in circles. It's like the shape is dancing!
- 15. Measurements that describe the size of a shape. Think of it as the recipe for building something - how long, how wide, how tall.
- 19. Four-sided shapes with one pair of parallel sides. It's like a wonky rectangle.
- 21. A pyramid with a square base. Picture a pyramid-shaped tent with a square bottom.
- 22. Four-sided shapes with opposite sides equal and all angles at 90 degrees. Think of a sheet of paper - it's a rectangular shape.
- 23. How tall something is. Imagine a cereal box; the height is how high the box stands.
- 24. Fancy four-sided shapes where opposite sides are parallel (like railroad tracks) and equal in length.
- 25. A special number (about 3.14) used in circles and round things. It's like the VIP guest at the geometry party.
Down
- 2. A 3D shape with six faces that are rectangles. It's like a shoebox.
- 5. One of the flat surfaces of a solid shape. Picture a cube; each side is a face. It's like the faces of a dice.
- 6. A fancy math recipe for finding something, like the area or volume of a shape. It's like your secret code to unlock math mysteries.
- 8. Turning or spinning a shape around a fixed point. Imagine turning a steering wheel - that's rotation!
- 10. An unfolded, flat version of a 3D shape. It's like taking a box apart and laying it flat before you put it together.
- 11. 3D shapes with a polygonal base and triangular sides that meet at a point on top. Imagine an ancient Egyptian pyramid.
- 12. 3D shapes with two identical, parallel bases and rectangular sides. Think of a soda can - it's a cylindrical prism.
- 13. When two shapes are exactly the same in size and shape. It's like having two puzzle pieces that fit perfectly together.
- 14. When you round a number to make it easier to work with, like saying 3.14 instead of 3.14159. It's like giving an estimate, not exact but close enough!
- 15. The distance across a circle, going through the center. If a circle were a pizza, the diameter would be the length of the biggest slice.
- 16. A 3D shape with six faces that are squares. It's like a box of dice.
- 17. A 3D shape with triangular bases and three rectangular faces. Imagine a Toblerone chocolate bar.
- 18. The amount of space inside a shape. Imagine you're carpet shopping; you'd want to know the area to make sure you buy enough carpet to cover the whole floor.
- 20. The bottom side of a shape, usually the one that everything else sits on. Like the base of a pyramid or the bottom of a rectangle.
