Homework Due 2-24-16

7th: Create a comic (tell a story that defines in words and pictures) for the phrase--”Balance an Equation”

8th: Choose a popular dance song (Watch Me, Land of 1000 Dances, etc) and describe in detail how transformations are shown through the dance moves.

Alg: Watch this Khan video and take notes.

Math Week 2-22-16

7th: Students use a balance model to solve equations.

Helpful videos from Math Antics:

Solving Basic Equations Part 1

Solving Basic Equations Part 2

Solving Two-Step Equations

CCSS: 7.NS.1. Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients. 7.NS.4. Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. a. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.

8th: Students practice vocabulary and notation related to rigid motions (e.g., transformation, image, and map). Students map a rigid motion that moves or maps one figure to another figure in the plane. Students understand that a translation, reflection, or rotation preserves congruence.

Also some helpful videos for this week:

CCSS: 8.G.Understand congruence and similarity using physical models, transparencies, or geometry software. 1. Verify experimentally the properties of rotations, reflections, and translations: a. Lines are taken to lines, and line segments to line segments of the same length. b. Angles are taken to angles of the same measure. c. Parallel lines are taken to parallel lines. 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.
