### Lesson Objective

Students will know how mathematicians read, write, and represent numbers in the thousands?

### Lesson Plan

Lessons by Edward Brooke Charter School:

I.                   Curriculum Standards

ü Count by 3 to 30 and 4 to 40, starting at any multiple of 3 or 4.   [M.1.2.a]

ü  Count by 100 and 1000, starting at any number to a million. [M.1.2.b]

ü  Identify place value of digits up to a million. [M.2.2.a]

ü  Write numbers in basic expanded form (e.g., 6091 = 6000 + 90 + 1). [M.2.2.b]

ü  Demonstrates an understanding of the values of digits up to a million (e.g., that in 21,054, the 1 represents 1,000). [M.2.2.c]

ü  Name and write, in numerals and words, whole numbers to 10,000. [M.3.2]

II.                    The Point

How do mathematicians read, write, and represent numbers in the thousands?

III.                Materials Needed

Copies of 2.5.5 Math Message

Copies of 2.5.5 Math Workout

Copies of 2.5.5 Worksheets (A, B,C as needed)

2.5.5 Teacher Reference page (Routines with Place Value Tools)

Base 10 Blocks

Place Value Mats

Numeral Cards

Slates and Markers

Classroom Place Value Flip Chart

IV.                 Lesson Outline

Time:  60 Minutes

10 min. –   Math Message

30 min. -    Reading, Writing, and Showing Numbers in the                                                                Thousands

15 min. –   Math Workout

5 min. –   Summary

V.             Learning Activities

1.   Math Message (10 min.)

Tell students that the symbol for drawing a big cube is                    .

Students work to independently complete 2.5.5 Math                                                      Message. (5 min.)

Go over the answers as a whole class.  Model the statements                                       of equality with the base-10 blocks. (5 min.)

2.  Reading, Writing, and Showing Numbers in the Thousands (30 min.)

Flexible Practice:

Use some of the following activities to help your students develop an             understanding and fluency with numbers in the thousands.

See the 2.5.5 Teacher Reference page for many examples of ways to have students develop an understanding and fluency with place value in the thousands.  Many of these tasks can be completed in whole group practice, small group work, partner work, or 1:1.

For these activities, students will need base-10 blocks, place value mats, slates, number cards, etc.  Students can also use the class place value flip chart to display numbers.

There are 3 different worksheets A, B, and C to choose from.

3.  Math Workout (15 min.)

Students complete 2.5.5 Math Workout

4.    Summary (5 min.)

How do mathematicians read, write, and represent numbers in the     thousands?
