**The main focus for these two weeks will be addressing Mathematical Reasoning standards all of which are considered Key Standards for the seventh grade. The listed Algebra and Functions standards may be met as a result of the activity but they are not intended to be the main focus.**

**Main Activity**

Interactive Mathematics Text

**p. 4** Hop, Skip and Jump Activity

*This activity includes patterns, mathematical reasoning, and generalizing algebraically. It can be used as a vehicle for the introduction of algebraic thinking, vocabulary and the use of algebraic expressions.*
Traffic Jam Activity

*Alignment to CA Mathematics Standards:*

**Algebra and Functions**

1.1 use variables and appropriate operations to write an expression, equation, inequality, or system of equations or inequalities which represent a verbal description (e.g.,
three less than a number, half as large as area A)

**Mathematical Reasoning**

**1.1** analyze problems by identifying relationships, discriminating relevant from irrelevant
information, identifying missing information, sequencing and prioritizing information,
and observing patterns

**1.2** formulate and justify mathematical conjectures based upon a general description
of the mathematical question or problem posed

**1.3** determine when and how to break a problem into simpler parts

**2.6** express the solution clearly and logically using appropriate mathematical notation
and terms and clear language, and support solutions with evidence, in both verbal
and symbolic work

**Extensions**

MAC Text

**pp. 32-35** - Powers and Exponents

**pp. 136-139** - Sequences

**pp. 24-32** - Variables and Expressions

*Alignment to CA Mathematics Standards:*

**Algebra and Functions**

1.2 use order of operations correctly to evaluate algebraic expressions such as 3(2x+5)^2

1.4 use algebraic terminology correctly (e.g., variable, equation, term, coefficient, inequality, expression, constant)

2.1 interpret positive whole number powers as repeated multiplication and negative
whole numbers as repeated division or multiplication by the multiplicative inverse.
Simplify and evaluate expressions that include exponents.

**Mathematical Reasoning**

**1.1** analyze problems by identifying relationships, discriminating relevant from irrelevant
information, identifying missing information, sequencing and prioritizing information,
and observing patterns

**Assessment**
- Students will be given the problem for 15 pairs of people. They will be able to explain their answer using the generalized formula n(n+2) equals the minimum number of moves to complete the problem.
