MATHEMATICS-11
ESSENTIAL UNIT 2 (E02)
(Introduction To Algebra)
(July 2013)
Unit Statement: In this unit, the student will learn to use addition, subtraction, multiplication, and
division to solve one-step equations involving decimals and fractions. The student will also study
writing algebraic expressions involving whole numbers. In order to be successful in this unit, the
student is expected to be familiar with the Key Terms and Concepts listed below.
Essential Outcomes: (must be assessed for mastery)
Problem solving and higher order thinking components are essential for A-level mastery. Each TSW
can contain problem solving and higher order thinking components (as found in suggested text).
1. The Student Will identify variables and evaluate expressions with two variables. (2-1,
pp. 46–49)
2. TSW identify parts of an expression using mathematical terms. (2-2, pp. 50-53)
3. TSW produce expressions for sequences in a table. (2-3, pp. 54-57)
4. TSW model the perimeter and area of rectangles using grid paper and expressions. (pp.
58-59)
5. TSW determine whether a number is a solution of an equation. (2-4, pp. 62-65)
6. TSW solve whole number addition equations. (2-5, pp. 66-69)
7. TSW solve whole number subtraction equations. (2-6, pp. 70-72)
8. TSW solve whole number multiplication equations. (2.7, pp. 73-76)
9. TSW solve whole number division equations. (2-8, pp. 77-79)
10. TSW create equations to solve real-world problems. (pp. 53, 61, 74, 76 and 81)
Introduced and Practiced Outcomes: (taught not assessed)
1. The Student Will apply the correct procedure of adding, subtracting, multiplying and
dividing whole numbers. (p. 43)

Suggested Materials:
Teacher’s Edition, Chapter 2, Holt McDougal, Mathematics, grade 6.
Suggested Assessment Tools and Strategies:
 Attached rubric or teacher generated rubric that assesses ALL essential outcomes
(TSWs).
 Assessments created by the teacher (ExamView CD-ROM)
 Chapter 2 tests on the ‘Teacher One Stop’ CD-ROM or in the Assessment Resources
(Holt McDougal, Mathematics, Grade 6)
 Students keep a journal in which they write about real-life situations connected to
their TSW’s (TSW 10). Students can use this same journal to rewrite explanations
given as paragraphs as steps or a list (TE: p. 45). For TSW 2 they can record realworld math situations they experience at home, using both words and mathematical
symbols.
 Students design, create, and play a game (Don’t Say the Word, Memory, Pictionary,
Scrabble, Word Wall, etc.) where they can prove their understanding of the Key
Terms and Concepts (TSW 1-9).
Additional Resources:
 Sideways Arithmetic from Wayside School by Louis Sachar (see p. 45 TE)
 A Collection of Math, Grades 6-8 by Marilyn Burns
