Name: Geometric Solids Content Area: Math Grade Level: Kindergarten Time Frame: 45 min Prior to this lesson the students had a lesson on attributes. The children defined and identified attributes in different two-dimensional shapes. MA Framework Standard: Geometry K.G Identify and describe shapes (squares‚ circles‚ triangles‚ rectangles‚ hexagons‚ cubes‚ cones‚ cylinders‚ and spheres). 2. Correctly name shapes regardless of their orientations or overall size. Identify shapes as two-dimensional

of the geometric sequence 8‚ –16‚ 32 … if there are 15 terms? (1 point) = 8 [(-2)^15 -1] / [(-2)-1] = 87384 2. What is the sum of the geometric sequence 4‚ 12‚ 36 … if there are 9 terms? (1 point) = 4(3^9 - 1)/(3 - 1) = 39364 3. What is the sum of a 6-term geometric sequence if the first term is 11‚ the last term is –11‚264 and the common ratio is –4? (1 point) = -11 (1-(-4^n))/(1-(-4)) = 11(1-(-11264/11))/(1-(-4)) = 2255 4. What is the sum of an 8-term geometric sequence

Shapes Everything around us is made of shapes‚ from the smallest type of micro-organisms to the biggest structure you will ever see in your life. They are the faces of the 3D solids we see around us‚ either being there in its own‚ or being a mix between two or more polygons. Shapes resemble different things and delivers different thoughts when looking or passing by them through the day. Putting these shapes or joining the to form volumes gives as a huge number of volume‚ they could be in the form

Geometric mean From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search The geometric mean‚ in mathematics‚ is a type of mean or average‚ which indicates the central tendency or typical value of a set of numbers. It is similar to the arithmetic mean‚ which is what most people think of with the word "average‚" except that instead of adding the set of numbers and then dividing the sum by the count of numbers in the set‚ n‚ the numbers are multiplied and then the nth root of the resulting

processes an emerging sense of two- and three- dimensional geometric shapes and relative positions in space (Standards‚ 2012). Instructional Goal 1 Identify two-dimensional shapes and three-dimensional shapes. Learning Objective 1: Students will take and identify foam two-dimensional shapes square‚ circle‚ triangle‚ and rectangle from a mystery bag with 80% accuracy. Justification: The mystery bag is used to cover the foam shapes from view. Students will need to use their sense of touch and

& Sums Introduction A geometric sequence is a sequence such that any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. The common ratio (r) is obtained by dividing any term by the preceding term‚ i.e.‚ where | r | common ratio | | a1 | first term | | a2 | second term | | a3 | third term | | an-1 | the term before the n th term | | an | the n th term | The geometric sequence is sometimes called

State Shapes 1. One distinct shape is not better than another‚ as it depends on the state’s situation. Politically‚ compact states are by far the best. The government is close to all portions of the state‚ rather than any other state shapes. For example‚ Brussels in Belgium is more politically stable‚ mainly because of its ability to interact with the other portions of the state. In other state shapes‚ there is an area where it is more difficult to communicate with. For example‚ in a prorupt state

1 “Arithmetic vs. Geometric Means: Empirical Evidence and Theoretical Issues” by Jay B. Abrams‚ ASA‚ CPA‚ MBA Copyright 1996 There has been a flurry of articles about the relative merits of using the arithmetic mean (AM) versus the geometric mean (GM). The Ibbotson SBBI Yearbook took the first position that the arithmetic mean is the correct mean to use in valuation. Allyn Joyce’s June 1995 BVR article initiated arguments for the GM as the correct mean. The previous articles have centered

Erie‚ PA 16563 ABSTRACT - In industrial practice‚ position is the most widely used geometric tolerancing characteristic. A thorough understanding of the concepts associated with position tolerancing is‚ therefore‚ an essential skill that graduating engineering and engineering technology students should possess. In the Mechanical Engineering Technology program at Penn State Erie‚ The Behrend College‚ geometric dimensioning and tolerancing (GD&T) skills are introduced to students during an advanced
