  1. Ms. Lonsdale’s 7th Grade Math Class Notes for the week of February 24 to February 28th

  2. Homeroom Read SILENTLY until class begins.

  3. Monday 2-24-14 Bellwork

  4. Announcements • Tutoring until 4:15pm (Number properties) • Two weeks until the end of the term, use this time wisely!!

  5. Random Factoid Sea otters hold each other’s paws when they sleep so they don’t drift apart.

  6. What’s the difference?

  7. SOLID FIGURESThese are 3D, not flat like a plane figure.

  8. Just like polygons, these figures have special names!

  9. A FACE is the flat surface of the figure.

  10. An EDGE is where two faces meet.

  11. A vertex is a point, normally where edges meet.

  12. What are the properties of the following 3-d figure? • 6 faces, 12 edges, 8 vertices • 6 faces, 10 edges, 8 vertices • 8 faces, 12 edges, 6 vertices • 8 faces, 8 edges, 8 vertices 3a, 3b Day 1 (DOK 2)

  13. Practice Faces: Faces: Faces: Edges: Edges: Edges: Vertices: Vertices: Vertices: Name the number of faces, edges, and vertices for questions 3-11 on page 412 in the text book.

  14. Work It • Find the faces, vertices, and edges for the provided shapes. • You may use the actual shapes that Ms. Lonsdale has in the back of the room if you need help identifying these properties. • By the end of class, discuss with your group…. • What seems to be the relationship between the faces/vertices and the edges of any 3D shape? • If you complete this early, read pages 410-411 and write the definitions for each highlighted vocabulary word.

  15. Exit Ticket 2.) What are the properties of the following shape? ____ faces ____ edges ____ vertices 3a, 3b Day 1 (DOK 2)

  16. Homeroom Read SILENTLY until class begins!!

  17. Tuesday, 2-25-14 Bellwork

  18. Announcements • There are less than two weeks until the end of the term, use this time to complete extra credit and make-up work in order to bring your grades up! 

  19. Random Factoid A group of porcupines is called a “prickle.”

  20. Think It • What 2d plane shapes make up these figures?

  21. Prism – a 3-d figure with 2 parallel, congruent bases connected by rectangles. Each type is named after its base. **It has NO curved sides** Which one of the images above is not a prism? 3a, 3b Day 1 (DOK 2)

  22. Bases 2 rectangles (squares) Lateral Faces 4 rectangles (squares) Bases 2 rectangles Lateral Faces 4 rectangles Bases 2 triangles Lateral Faces 3 rectangles. Bases 2 pentagons Lateral Faces 5 rectangles. Bases 2 hexagons Lateral Faces 6 rectangles. Types of Prisms Rectangular Prism Cube Triangular Prism Hexagonal Prism Pentagonal Prism

  23. Think It • What is different between a prism and a pyramid?

  24. Base 1 square Lateral Faces 4 triangles. Base 1 triangle Lateral Faces 3 triangles. Base 1 rectangle Lateral Faces 4 triangles. Base 1 pentagon Lateral Faces 5 triangles. Base 1 trapezoid Lateral Faces 4 triangles. Pyramid – a 3-d figure with one base, triangular sides, and a vertex on top. *The base must be a polygon (not a circle) * It has NO curved sides Triangular Pyramid Square Pyramid Rectangular Pyramid Trapezoidal Pyramid Pentagonal Pyramid Which one of the images above is not a pyramid? 3a, 3b Day 1 (DOK 2)

  25. Cylinder – a 3-d figure with 2 circular bases and one curved side Which one of the images above is not a cylinder? 3a, 3b Day 1 (DOK 2)

  26. Sphere – a 3-d figure shaped like a ball 3a, 3b Day 1 (DOK 2)

  27. Cone – a 3-d figure with one circular base and one vertex. 3a, 3b Day 1 (DOK 2)

  28. Prism, Pyramid, Cylinder, Sphere, or Cone? Triangular Prism 3a, 3b Day 1 (DOK 2)

  29. Prism, Pyramid, Cylinder, Sphere, or Cone? Triangular Pyramid 3a, 3b Day 1 (DOK 2)

  30. Prism, Pyramid, Cylinder, Sphere, or Cone? Cone 3a, 3b Day 1 (DOK 2)

  31. Prism, Pyramid, Cylinder, Sphere, or Cone? Sphere 3a, 3b Day 1 (DOK 2)

  32. Triangular Prism 3a, 3b Day 2 (DOK 2)

  33. Cylinder 3a, 3b Day 2 (DOK 2)

  34. Rectangular Pyramid 3a, 3b Day 2 (DOK 2)

  35. Hexagonal Prism 3a, 3b Day 2 (DOK 2)

  36. Sphere 3a, 3b Day 2 (DOK 2)

  37. Pentagonal Pyramid 3a, 3b Day 2 (DOK 2)

  38. Exit Ticket 1.) What is the specific name for this shape? (If it is a prism or pyramid, name it by its base) 2.) What are the properties of the following shape? A. 8 faces, 8 edges, 8 vertices B. 8 faces, 18 edges, 8 vertices C. 8 faces, 18 edges, 12 vertices D. 7 faces, 12 edges, 18 vertices 3a, 3b Day 1 (DOK 2)

  39. Homeroom Read SILENTLY until class begins!!

  40. Thursday, 2-27-14 Bellwork What is the name of the figure below? • Rectangular Pyramid • Triangular Prism • Rectangular Prism • None of the above

  41. Announcements • Tutoring tonight (review of 3D shapes) • Remember to keep working on your make-up work/extra credit! • Step up packets available after 2nd period.

  42. Random Factoid A cat’s nose is ridged with a unique pattern, just like a human fingerprint.

  43. NETS OF 3D SHAPES! Video

  44. Nets: Show what shapes the faces of a solid figure are and how they fit together

  45. Prism Nets: 2 polygons (the bases) and 3 or more rectangles (the lateral faces)

  46. Pyramid Nets: 1 polygon (the base) and 3 or more triangles (the lateral faces)

  47. Cylinder Nets: 2 circles (bases), 1 rectangle (the middle)

  48. Cone Nets: 1 Circle (base), 1 sector
