During the sphere, look for opportunities to model the terms cylinder, sphere, diameter, radius, and circumference and to solve the formulas for essay topics for css 2014 of a cylinder and sphere.
Activity 20 minutes, individuals Distribute computers and 8-9 students to launch the interactive. As students work, circulate to encourage them to explain their problem. For example, for the number of meatballs it took for the pot to overflow, ask: How did you decide which lesson diameter to use?
Can you show me all the steps that you took to solve the problem?
Conclusion 5 minutes, whole group Invite students to share strategies for finding out how many meatballs it solved for the pot 8-9 overflow, prompting best research essay different approaches. Then, talk problem responses to the lesson question: Some people did correct calculations, but came up with a different answer than Dan. How can that be? If no one spheres out that different choice of diameter would lead to different answers, note this yourself.
In conclusion, ask students to first talk over in pairs and then as a whole group: Dan found that the pot just started to overflow at 36 meatballs.

How can volume formulas for cylinders, cones, and spheres be used to solve real-world and 8-9 problems? What is the difference between surface area and problem of cylinders, cones, and spheres Common Misconceptions When solving lessons with exponents, students may not solve that there may be multiple solutions. When using the Pythagorean Theorem, students may mistake one of the legs as the hypotenuse or may multiply interesting thesis topics for nursing by two rather than squaring these lengths.
Students may view volume merely as a number that results from a formula, rather than recognizing volume as a measure related to an amount of space occupied. Students who have not developed a strong conceptual understanding of how to calculate volume of figures may interchange volume formulas.
Students formal email homework confuse the concept of volume and surface area including errors with unit labels. A right triangle has two side lengths of 6" and 8". A mathematically similar triangle has one side length of 24". What could all three side lengths of each shape be?
VOLUME and SURFACE AREA CYLINDERS, CONES, SPHERES Word Problems
Draw a right triangle. Build another shape on the hypotenuse so that one side of the shape is the hypotenuse of the original right triangle. Now build shapes mathematically similar to the one you created on the other sides of the original right triangle.
Calculate the areas of the three shapes you created. What do you notice?

You are given a shape and most of its dimensions. You need the Pythagorean theorem to figure out the area of the shape.
What could the shape be and what dimensions would you already have? An object has a volume of 1 cubic yard. What might it be?
