 Number & Operations Mathematics Curriculum Standards 3108 - Geometry Internet Resources Checks for Understanding (Formative/Summative Assessment) 2.1 | 2.2 | 2.3 | 2.4 | 2.5 | 2.6 Analyze properties and aspects of pi (e.g. classical methods of approximating pi, irrational numbers, Buffon�s needle, use of dynamic geometry software). 3108.2.1 �Buffon's Needle Problem - Animated site showing this problem. Buffon's Needles Lab Report -Explore a Monte Carlo method of estimating the value of pi. Discovering pi - This particular activity allows students to discover why pi works in solving problems dealing with finding circumference. Computing Pi - Interactive tool; This activity allows for the investigation and comparison Approximate pi from a table of values for the circumference and diameter of circles using various methods (e.g. line of best fit). 3108.2.2 � Recognize and apply real number properties to vector operations and geometric proofs (e.g. reflexive, symmetric, transitive, addition, subtraction, multiplication, division, distributive, and substitution properties). 3108.2.3 � Add vectors graphically and algebraically. 3108.2.4 Learning about Properties of Vectors and Vector Sums Using Dynamic Software- Lessons that help students develop an understanding of vectors and their properties. Students manipulate a two vectors to control the movement of a plane in a gamelike setting. Vector Addition - explanation of concept. Vector Addition - Interactive site that lets students explore vector addition. Vector Addition - Interactive site; Drag two vectors around to see the sum of the vectors. The magnitude and direction of each vector can be manipulated. Components of all vectors are shown in equation form Multiply a vector by a scalar graphically and algebraically. 3108.2.5 � Analyze precision, accuracy, and approximate error in measurement situations. 3108.2.6 � State Performance Indicators Analyze, apply, or interpret the relationships between basic number concepts and geometry (e.g. rounding and pattern identification in measurement, the relationship of pi to other rational and irrational numbers) SPI 3108.2.1 � Perform operations on vectors in various representations. SPI 3108.2.2 � National Library of Virtual Manipulatives Number & Operations [Grades 9-12]

 Algebra Mathematics Curriculum Standards 3108 - Geometry Internet Resources Checks for Understanding (Formative/Summative Assessment) 3.1 | 3.2 | 3.3 | 3.4 | 3.5 | 3.6 Prove two lines are parallel, perpendicular, or oblique using coordinate geometry. 3108.3.1 � Connect coordinate geometry to geometric figures in the plane (e.g. midpoints, distance formula, slope, and polygons). 3108.3.2 � Find the equation of a circle given its center and radius and vice versa. 3108.3.3 Circle Equations - excellent information from Math is Fun, followed by twelve multiple-choice questions to check for understanding Find the equation of a circle - Java applet; use an analytical method to find the equation of the circle and then use the applet to change h, k and r to solve the same question graphically. Finally compare the two results. This exercise helps you in problem solving and also to gain a deep undertanding of the properties of the circle.� The equation of a circle - Example of how to find the equation of a circle and practice questions. The equation of a circle - how to obtain and use the�standard form�of the�equation of a circle in Geometry. Apply the midpoint and distance formulas to points and segments to find midpoints, distances, and missing information in two and three dimensions. 3108.3.4 � Use mapping notation to identify the image of a transformation given the coordinates of the pre-image. 3108.3.5 � Identify a transformation given its mapping notation. 3108.3.6 � State Performance Indicators Use algebra and coordinate geometry to analyze and solve problems about geometric figures (including circles). SPI 3108.3.1 Circle Equations - excellent information from Math is Fun, followed by twelve multiple-choice questions to check for understanding Use coordinate geometry to prove characteristics of polygonal figures. SPI 3108.3.2 � Describe algebraically the effect of a single transformation (reflections in the x- or y-axis, rotations, translations, and dilations) on two-dimensional geometric shapes in the coordinate plane. SPI 3108.3.3 � National Library of Virtual Manipulatives Algebra [Grades 9-12]

 Data Analysis, Statistics, & Probability Mathematics Curriculum Standards 3108 - Geometry Internet Resources Checks for Understanding (Formative/Summative Assessment) Determine the area of each sector and the degree measure of each intercepted arc in a pie chart. 3108.5.1 Circles - twenty-three java applets for investigating circles Translate from one representation of data to another (e.g., bar graph to pie graph, pie graph to bar graph, table to pie graph, pie graph to chart) accurately using the area of a sector. 3108.5.2 � Estimate or calculate simple geometric probabilities (e.g., number line, area model, using length, circles). 3108.5.3 � State Performance Indicators 5.1 Use area to solve problems involving geometric probability (e.g. dartboard problem, shaded sector of a circle, shaded region of a geometric figure). SPI 3108.5.1 � National Library of Virtual Manipulatives Data Analysis & Probability [Grades 9-12]
