Homework: Define scalene triangle, isosceles triangle, equilateral triangles, trapezoid, isosceles trapezoid, kite, rhombus, parallelogram, rectangle, and square. Determine the number of diagonals for a heptagon and an octagon (at least) to determine the pattern for the number of diagonals that a polygon has. Assessment 11-3 – 8, 10, 10, 13. Assessment 11-3B – 11. Assessment 11-4 – 3, 4, 9 a and b, 10 and 15. Test will

February 4 – Quiz on homework. Discussed project assigned. Discussed naming regular polygons, triangles, and special quadrilaterals. Discussed hierarchy of polygons. Homework: Section 11-3A – 5 ,6,7,9 and 11-3B- 1and 5. Test on
Chapter 11 could be in two weeks.
February 2 – Returned the quiz. Discussion including: properties of distance that included the triangle inequality; perimeter and arc length formulas; simple, closed curves, polygons and convex/concave, diagonal and interior of a polygon. Homework: Know perimeter formulas for rectangle, square and circumference of a circle. Know the formula for length of an arc. Define: polygon and know the names of polygons through 12 sided. Assessment 11-2 A – 16, 18-
21. Page 664 – TIMSS, NAEP questions too. Assessment 11-3A – 1,2, 3,and 4.
January 28 - Quiz. Discussed linear measure. Handout was what primary children studied for measurement over 100 years ago. Homework: Memorize relationships in Table 11-6, 11-7 and 11-8 in the textbook. Complete or get help with
any homework questions in section 11-1. Assessment 11-2A – 1, 2 a, b, 3, 5, 6, 7, 8, 9, 10, and 14. I will be visiting a student teacher tomorrow morning so out of the office.
January 26 – Allowed students to check handout using my key. Discussion of lots of vocabulary. Homework: Define – complementary angles, supplementary angles, circle, sphere, chord, diameter, radius, arc (major, minor, semicircle,) and other vocabulary to identify only including central angle, secant line, tangent line, sector, annulus, and segment of a circle. Assessment 11-1 A - 9, 14, and 15. Begin reading Section 11-2.
January 21 – Returned quiz. Introduced class. Reviewed some vocabulary from last week and discussed new terms including interior of an angle and adjacent angles. Angles and lines subdivide a plane into three disjoint sets of points.
Read three axioms from page 638. Discussed using a protractor and ways angles are measured. Homework: Define – angle, acute angle, obtuse angle, right angle, straight angle, and adjacent angles. Assessment 11-1 A – 4, 6, 7, 8,.
Handout sheet of angles to measure to the nearest degree.
January 14 – Returned the quiz from last time. Gave a quiz on homework. Discussed numerous definition and relationships. Homework: Define – “between”, segment, ray, parallel planes, parallel lines, and skew lines. Students
should understand and use the following: open segment, half-line, concurrent lines, intersecting lines, and a line parallel to a plane or intersecting a plane. Students must know symbols for or how to name: parallel, segment, ray, length of a segment, line, and planes. Assessment 11-1A – 1, 2 a – d, 3, 10, 11, and 12.
January 12 - Answered questions about the syllabus, then a quiz on the syllabus. Discussed parts of an axiomatic system, undefined terms, van Hiele levels and made some definitions. Homework: READ section 11-1. KNOW parts of an axiomatic system; what the undefined terms are for this semester and how to represent them; and be able to write a sentence definition for: collinear points, noncollinear points, coplanar points, and noncoplanar points.
