**Comments:**

Harrisons student population is 594. 85% Hispanic, 12% Anglo, 3% Asian, African
American, Native American, Free and

Reduced Lunch is 93%.

**I. Description of Unit:
**This lesson will be an intro to building formulas. Students will continue
the natural process by learning how to substitute

variables, work with concrete verse abstract concepts, and continue algebraic concepts .

**A. How does this lesson fit into the unit?**

**▪ Previously learned concepts
**Students will need to know basic operations including addition, subtraction,
multiplication, and division as well

as reading, writing, and sequence of events. They will need to have some experience with Order of Operations ,

Distributive Property , grouping , simplifying, solving for unknowns , multiplying decimals, formulas, and

variables.

**▪ Concepts to be learned in this lesson
**Order of operations, combining like terms, and discovering multiple ways to
solve problems are just a few of

the concepts students will be learning in this lesson. Eighth grade is the grade level that we need our students to

begin developing their algebraic thinking.

**▪ Concepts to be used in future lessons
**For future lessons and extensions, students will formalize the distributive
property, arrive at formulas on their

own, reinforce the order of operations , and continue to work with combining like terns .

**B. Instructional sequence for unit
**This unit is being introduced the 4^th week of the last 9 weeks. The lesson
is a continuum of the algebraic process and will be a

springboard for formalizing the distributive property . Students will derive at formulas while working with variables and formulas.

**II. Plan of the research lesson**

**A. Goals of the research lesson:
**The goals for this lesson are for students to multiply decimals, combine
like terms, correctly label units, substitution with

variables, and solve equations .

**B. How does the lesson fit into the overarching lesson
study goal?
**The lesson will fit into the overarching goal by helping them make the leap
from concrete to abstract thinking because

they are working with things they are familiar with. Hopefully, the lesson will lead students toward mastery of solving

variables. We want the students to see why variables are important with real world application. Students will combine

like terms and all these things should help to make our students better prepared for high school.

**C. Steps of the research lesson: **(See attached
table)

**D. Things to prepare /materials:
**The things that require preparation are:

• Permission slips for filming

• Transparencies and visa-v pens

• Handouts

• Copies of the student handout

• Large paper to display student findings

• Markers

• Overhead menu
