From the Latin: tessela, a small, square stone used in Roman mosaics. A plane tessellation is a pattern made up of one or more shapes, completely covering a surface without any gaps or overlaps.

Thinking about Math for the second semester…

7 weeks from January 2nd to February 16th: 17 45-minute periods, 7 90-minute periods.

**Homework:** Monday and Tuesday nights. To hand in or check in their books.

**Quiz/Test every Thursday:** current material plus some MCAS problems

**Problem Solving due every Monday:** We should make these up ourselves, and make them much less of a word problem and more of an exploration of math in our environment. (I already have an idea from the kitchen: what’s the best way to arrange pizza slices on a rectangular tray for heating and serving?) Challenging, but accessible to everybody, and fun.

Exhibition will be tessellations, and this calendar leaves us a week before Exhibition to fill in any gaps.

I’d like to use the time after the test on Thursdays for spiral review of simplifying expressions, slope in all its nefarious forms, and inequalities, and for learning how to use the graphing calculators.

**Scope:**

Basic geometry language

Angles

Intersecting and Parallel Lines, Transversals

Interior and Exterior Angle Measurements

Congruence and Similarity

Transformations

Pythagorean Theorem

**Sequence:**

Lines. Vocabulary, naming. *One Week*

Segments and Angles. Congruence. Similarity. transversals, interior and exterior angles. *Two Weeks*

Shapes. triangles and quadrilaterals. 2 and 3-dimensional. *One Week*

Pythagorean Theorem. unknown side lengths, distance between points in a coordinate system. Real-world applications. *Two Weeks. Minimum.*

Transformations. Dilation, translation, rotation, reflection. On unmarked and coordinate planes. Tessellations. *Two Weeks. Minimum.*

**MCAS(Massachusetts Comprehensive Assessment System) Research:**

heavy on 2) congruence and similarity; 4) Pythagoras; 6) Transformations
