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 (lying

Math in My Life This year in Algebra 2 class I have learn some very interesting and important topics. Throughout this past school year I have grown and learned how to use these newly learned skills and my understanding of algebra is now complete. In math class this year‚ I believe I did fairly well and received almost got all A’s. I think I passed this class is because math in general comes easy to me. I only studied in the beginning of the year‚ as the latter part of the year came much easier.

The work of Maurits Carnelis Escher (M.C. Escher) is widely considered the most popular example of the mathematical influence in art. Though never formally trained in math‚ Escher’s initial interest in decorative art sparked a curiosity in certain mathematical areas such as geometric shapes‚ tessellations and spatial planes/demensions. His interest in both aesthetic and logic resulted in provoking visual representations of multiple dimension. Escher’s understanding of mathematics in combination

Ellyn McCall MFG-1107 Term Report 11/7/2011 Mathematics and Music Theory In the study of mathematics‚ at first glance it seems clear that mathematics is cut and dry‚ black and white‚ completely numerical. But in many ways‚ mathematics extends into other areas of life. While some people may think of mathematics and art as being two separate entities‚ Math is very present in many artistic endeavors. Music‚ commonly referred to as an art‚ would not be possible without the relationship it shares

Math Project II My book was geared toward a 3rd grade level. According to the TEKS 3rd grade geometry and measurement: the student applies mathematical process standards to analyze attributes of two-dimensional geometric figures to develop generalizations about their properties. The first math problem in the book is one of probability. What are the “odds” that 3 children can get two bedrooms clean in 1 hour? This would be an experimental probability problem because I am conducting an “experiment”

Fatima Jama Dr. Kembitzky Geometry May 9 2013 Hexagon Area Hello Timmy! I heard you have been sick with the flu for a while so‚ I took the liberty of getting you on your feet before class so you are not lost. So this paper will help you find the area of a hexagon using special right triangles‚ using trigonometry‚ breaking the hexagon into smaller polygons‚ and even show you how to construct one! So let’s get started‚ this hexagon has a radius of 6 cm‚ keep in mind that there are many different

Justifications for Geometry Proofs – Ch 3 Properties of Equality (=): Addition: a = b → a + c = b + c Subtraction: a = b → a – c = b - c Division: a = b → a / c = b / c Multiplication: a = b → a * b = b * c Distributive: a ( b + c ) = a * b + a * c Substitution: a = b → a can be substituted for b in an equation Properties of Congruence and Equality ( and =): Reflexive: ab = ab or Symmetric: a = b → b = a or ∠A ∠B → ∠B ∠A Transitive: a = b and b = c → a = c or ∠A

found on the papyrus. The Moscow Papyrus: In the 19th century‚ an Egyptologist- Vladimir Golenishchev‚ found the papyrus and brought it to Russia. The Moscow papyrus contains only about 25 math problems. Of the 25 math problems‚ 7 of them are geometry. The papyrus is now located in the Museum of Fine Arts in Moscow The Ancient Egyptians obviously had a very good understanding of mathematics. They looked for patterns and found ways to add‚ subtract‚ multiply and divide. They came up with many
