ESSENTIAL UNIT 3 (E03)
(Decimals)
(July 2013)
Unit Statement: In this unit, the student will read, write, compare, and order decimals. The
student will also use rounding to estimate answers to problems that involve decimals and
solve decimal equations. 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 name (in expanded, standard, and word form), compare, and
order decimals using place value and number lines. (3-1, pp. 94-97)
2. TSW estimate the sum, difference, product, and quotient of decimals by rounding,
using compatible numbers, and front-end estimation. (3-2, pp. 98-101)
3. TSW solve addition and subtraction of multi-digit decimals using the standard
algorithm for each operation. (3-3, pp. 104-107)
4. TSW multiply the decimal (expression) by whole numbers and by decimals. (3-4,
pp. 112-115)
5. TSW divide the decimal (expression) by whole numbers and by decimals. (3-5 and
3-6, pp. 116-122)
6. TSW solve (story) problems by interpreting the quotient. (3-7, pp. 123-125)
7. TSW solve (one-step) equations involving decimals. (3-8, pp. 126-129)
8. TSW demonstrate the correct procedures and strategies solving real-world
problems with decimals by using variables and writing expressions. (pp. 97,
109, 115, 120, and 131)
Introduced and Practiced Outcomes: (taught not assessed)
1. The Student Will identify the place value of underlined digits (p. 91).
2. TSW solve addition, subtraction, multiplication, and division of whole numbers (p. 91).
3. TSW identify values for exponents (p. 91).
4. TSW solve one-step equations (p. 91).

Suggested Materials:
Teacher’s Edition, Chapter 3, 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 3 tests on the ‘Teacher One Stop’ CD-ROM or in the Assessment
Resources (Holt McDougal, Mathematics, Grade 6)
 Students keep a Math journal in which they write about real-life situations
connected to their TSW’s (TSW 8, TE: p. 93). Students can use this same journal
to rewrite explanations given as paragraphs as steps or a list (TE: p. 45).
 Students do online research to learn more about Puget Sound’s ferry system (or
any other transport system). Then ask them to use the schedules and/or information
about the routes to write original problems that involve decimal operations (TSW
8, p.131 TE).
 Students can 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 1-7).
Additional Resources:
 G is for Googol: A Math Alphabet Book by David Schwartz (see page 93 TE).
 Family Math by Jean Kerr Stenmark, Virginia Thompson, Ruth Cossey, and
Marilyn Hill
Technology Links:
 Destiny WebPath Express (school library site)
 Lesson Tutorial Videos for every lesson (CD-ROM, Holt McDougal, Mathematics,
Grade 6)
 Power Point Presentations for every lesson (CD-ROM; Teacher One Stop, Holt
McDougal, Mathematics, Grade 6)
