High School Math The Standards Based Way Day 5 Nicole Spiller West Georgia RESA

Problem of the Day In the figure below, point Q is fixed and point P starts at 4 and moves left along the x-axis. As P moves left along the x axis toward O, the area of POQ changes. Use the information given to complete the table below to show how the area of POQ changes as P goes from the position shown to the origin O. x-coordinate of P Area of POQ

Essential Question/Enduring Understandings What math is in Unit Six? What math is in part five of Unit Four? How does assessment impact what students should know and be able to do?

Assessment What is assessment? What is the difference between assessment and grading?

Thoughts on Grading The Case against the zero Grading: Are grade an accurate reflection of student learning?

Thoughts on Assessment Open Ended Items Will this be on the test?

Assessment For Learning –Usually Formative –Usually detailed, specific, and descriptive feedback –Checks learning to determine what to do next –Designed to assist student and teacher Of Learning –Usually Summative –Usually compares student learning to other students –Checks what has been learned to date –Doesn’t need to involve student Both are important!!! We must have a balance!

Assessment for Learning 1.Students are involved so a shared language and understanding is developed. 2.Students receive specific, descriptive feedback about the learning, during the learning. 3. Students collect, organize, and communicate evidence of their learning to others.

Assessment for Learning 4. Teachers adjust instruction in response to ongoing assessment information received from students and selves. 5. A safe learning environment invites further risk taking, mistake making, goal setting, and support for learning. GMSA Conference Assessment for Learning 2/3/2005

Unit 6 – Coordinate Geometry Pre Requisites: –Plotting points in all quadrants –Scatter plots –Lines and systems of lines, including finding equations of lines, finding slopes of lines, and finding the slope of a line perpendicular to a given line. –Pythagorean Theorem

Overview of Unit 6 This unit investigates the properties of geometric figures on the coordinate plane. Students develop and use the formulas for the distance between two points, the distance between a point and a line, and the midpoint of segments. Focusing students’ attention on a coordinate grid as a reference for locations and descriptions of geometric figures strengthens their recognitions of algebraic and geometric connections.

Essential Question/Enduring Understandings Algebraic formulas can be used to find measures of distance on the coordinate plane. The coordinate plane allows precise communication about graphical representations. The coordinate plane permits use of algebraic methods to obtain geometric results.

Key Standards MM1G1: Students will investigate properties of geometric figures in the coordinate plane. Determine the distance between two points. Determine the distance between a point and a line. Determine the midpoint of a segment. Understand the distance formula as an application of the Pythagorean Theorem. Use the coordinate plane to investigate properties of and verify conjectures related to triangles and quadrilaterals.

Related Standards MM1G2: Students will understand and use the language of mathematical argument and justification. Use conjecture, inductive reasoning, deductive reasoning, counterexample, and indirect proof as appropriate. Understand and use the relationships among a statement and its converse, inverse, and contrapositive. MM1G3: Students will discover, prove, and apply properties of triangles, quadrilaterals, and other polygons. Understand, use, and prove properties of and relationships among special quadrilaterals: parallelogram, rectangle, rhombus, square, trapezoid, and kite. Find and use points of concurrency in triangles: incenter, orthocenter, circumcenter, and centroid.

Related Standards MM1P1: Students will solve problems (using appropriate technology) MM1P2: Students will reason and evaluate mathematical arguments MM1P3: Students will communicate mathematically MM1P4: Students will make connections among mathematical ideas and to other disciplines MM1P5: Students will represent mathematics in multiple ways
