Week at a Glance: August 26, 2013
Current Unit: Unit 1a Geometric Transformations
Unit Standards: MCC8.G1, MCC8.G2, MCC8.G3
Crosswalk COACH Connection: Lesson 24
This week in math, we will complete the first unit, Rigid Transformations. We will begin the week with a continuation of the reflections exploration. Thereafter, students will work on tasks designed to review all of the rigid transformations (translations, rotations, and reflections). In addition, students will use rigid transformations to determine if a set of figures are congruent.
Students will take a 2-part unit assessment on Thursday and Friday. Part I of the assessment will be a performance task that will require students to perform all of the rigid transformations. Part II will be a traditional type test on which students will have to answer questions.
In order to be well prepared for the assessment, it is important that students know and understand the unit terms, which are listed in the week at a glance from the 2 weeks.
Below is an outline of this week's agenda. This outline is subject to change based on the needs of the students.
MON

TUE

Week at a Glance: August 19, 2013
Current Unit: Unit 1a Geometric Transformations
Unit Standards: MCC8.G1, MCC8.G2, MCC8.G3
Crosswalk COACH Connection: Lesson 24
This week in math, we will continue to study the standards in Unit 1a: Rigid Transformations and Congruency. Students will focus on rotations and reflections, particularly describing the effect that these transformations have on a figure.
On of the big ideas of this unit is that rigid transformation produce images that are congruent to the original figure. Students will recall congruency and demonstrate their understanding by writing congruence statements to identify corresponding sides and angles of two figures. In addition, students will use transformations to determine if figures are congruent.
Again, it is important that students are well versed with the vocabulary to be most successful with this unit. The unit terms include:

*********************************************************************************
This week in math, we will continue to study Geometric Transformations. We will focus on translations on Monday and Tuesday. Students will continue to explore translations and learn how to write and interpret translations in general form (algebraic) from a graph or a set of ordered pairs.
Monday:
-- Translations Exploration (continue from Friday)
-- Writing / Reading translations in general form
*HW - Translations Practice worksheet
Tuesday:

To be successful in this unit, it is important that students know the terms. They need to study them on a nightly basis until they have mastered all of them. Other prerequisite skills include: understanding the coordinate plane, plotting and reading points on a coordinate graph and integer operations.

Week at a Glance: August 5, 2013
Generally, I try to publish the "Week at a Glance" at the beginning of each week to let you know what we will study in math for the week. Each Monday (or first school day of the week), students are instructed to copy down the weekly agenda into their notebooks. Please check your child's agenda on Monday evenings and review the weekly math game plan with them.
This week in math, we will begin the week with a Unit Pre-test on Monday. Following the brief pretest, students will create a picture by plotting ordered pairs on the coordinate plane. This task will reinforce some of the prerequisite skills for the first unit, including plotting and reading ordered pairs and working with a coordinate grid.
For the remainder of the week, we will work on Unit 1a: Geometric Transformations. The unit will be introduced with a hands exploration of rigid transformations: translation, rotation, reflection.
Thereafter, we will study each of the transformations in isolation. Later this week, we will begin a focus on translations. Students will perform and interpret translations. They will need to know how to read and write translations verbally as well in the general form (algebraically). They will also need to be able to identify translations from pictures as well as sets of ordered pairs.
Students will need to know the following terms:
