1. Get out lesson 24 from Monday We need to fix number 4

2. 4a 3 sides 4 X 5 = 20+20+20 2 sides 5 X 5 = 25+25 4 interior walls 2 X 4= 8+8+8+8 2 holes 2X2 = (4+4) 4b Top/bottom 10 X 10 = 100+100 4 sides 3X10=30+30+30+30 Interior walls 2X3=6+6+6+6 Holes 2X2=(4+4) Attached 4X5=(20)

3. agenda Finish lesson 24 Finish our question form yesterday Start lesson 25 Exit ticket

4. Will the volume or the surface area of a 3-D change when the shape is separated into sections?

5. Same groups You will be given a rectangular prism The prism maybe whole, or cut into pieces, the steps will be the same Fill the box or boxes with the corn pops. You can count them as you add them or you count them after you fill up the box/boxes.

6.

7. Now using equations and calculation find volume Formulas for volumes of solid shapes come from the same concept (The area of the base)(height of shape) Base X height This works if base is circle (πr 2 ) rectangle(bh) and triangle(1/2bh)

8. If you have more than one shape, find the volume of one and then add. Whole boxTwo trianglesThree triangles Two rectangles Three rectangles Rectangles and triangles Number of corn pops Measured area Surface area

9. Which changed Surface Area or Volume?
