Q3W19 Pre-Algebra

Teacher Carol Barnes Pre-Algebra 8th Q3W19 Jan. 10-14 Geometry, then Functions
Standard(s) Taught

MAFS.8.G..1.2  Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given
two congruent figures, describe a sequence that exhibits the congruence between them.

MAFS.G.1.3  Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

MAFS.8.F.1.1  Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is a set of ordered pairs consisting of an input and the corresponding output.

Learning Targets and Learning Criteria
• explain how transformations can be used to prove that two figures are congruent.
•  perform a series of transformations (reflections, rotations, and/ortranslations) to prove or disprove that two given figures are congruent.
• describe a sequence of rigid motions to map one figure onto another.
•  describe the changes occurring to xand y- coordinates of a figure after a
translation, reflection, rotation, or dilation.
• reason that a 2-D figure is congruent to another if the second can b eobtained by a sequence of rotations, reflections, translation.
• describe the sequence of rotations, reflections, translations that exhibits the congruence between 2-D figures using words
• describe a sequence of rigid motions to map one figure onto another
Classroom Activities

Any student with an “I” incomplete last quarter must complete all missing assignments by the end of this week.  Please see Mrs. Barnes to arrange after school time to complete any missing tests, remediation, or corrections.

Monday/Tuesday:

Bell Ringer:

Whole Group:   Use worksheet called “Transformations” that was assigned for homework last Thursday.  It can be found at the link:  Transformations (review one page)    Use this link to listen to a teacher filling in the notes for class:

Small Group:  Work problems from Thursday’s homework from this link:  Transformations Review (2 pages)  page with classmates at your table.  Check answers with each other.  See key at teacher’s desk.

Independent:  Homework : Statistics Review due Wednesday. HW 14 Transformation Review

Wednesday No Bell Ringer

Whole group:  Go over HW 14 Transformation Review assigned on Monday

Small Group:  Work problems 1-2 on back of note-taking page with classmates at your table.  Check answers with each other.  See key at teacher’s desk.

Independent:  Homework 3: Statistics Review due Wednesday. Link: HW 3 Statistics

Thursday/Friday:

Transformations Test.  The test must be taken at school, so no link will be provided.

Whole Group:  None

Small Group:  None

Independent:  Noters for the Introduction to Functions at this link:  Intro to Functions Notes .  A video of a teacher going over the notes to our Introduction to Functions can be found at this link:  https://www.youtube.com/watch?v=ty8TQL2tpPQ

Assignments Due

Homework from last Thursday which is gone over on Monday (Transformations-review 1 page and Transformations Review-2 pages) are due for a grade on Wednesday before the test.

Transformations Test will be due on Thursday.

Homework 1: Intro to Functions is due next Monday
