### Lesson Objective

Students will know how mathematicians read, write, and represent numbers in the ten-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 ten thousand. [M.1.2.b]

ü  Identify place value of digits up to ten-thousand. [M.2.2.a]

ü  Demonstrates an understanding of the values of digits up to ten thousand (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]

ü  Locate numbers up to ten-thousand on a number line. [M.5.2]

ü  Order numbers up to 10,000. [M.6.2]

II.                    The Point

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

III.                Materials Needed

Copies of 2.5.10 Math Message

Copies of 2.5.10 Math Workout

Copies of 2.5.10 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.)

Students work to independently complete 2.5.10 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 Ten-Thousands (30                 min.)

Flexible Practice:

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

A: straight forward practice with place value and counting by 1s.

B: slightly more challenging questions relating to place value

C: items taken directly from past MCAS tests

(Feel free to use these worksheets for future practice as well.)

3.  Math Workout (15 min.)

Students complete 2.5.10 Math Workout

4.    Summary (5 min.)

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