Lesson: Place Value: Expanded Notation: Lesson 8
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 Identify place value of digits up to ten-thousand. [M.2.2.a]
ü Count by 100 and 1000, starting at any number to ten thousand. [M.1.2.b]
ü Locate numbers up to ten-thousand on a number line. [M.5.2]
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 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 Order numbers up to 10,000. [M.6.2]
II. The Point
Differentiated work toward mastery of Month 5 standards.
III. Materials Needed
Copies of Math Workout 2.5.8
Copies of 2.5.8 Math Message
Slates or blank paper for Math Message
Materials will vary based on centers activities
IV. Lesson Outline
Time: 45 Minutes (Wednesday Schedule)
10 min. – Math Message
30 min. – Math Centers/ Math Workout
5 min. – Summary
V. Learning Activities
1. Math Message (10 min.)
Students fill in < or > on the Math Message slip.
Students share their answers.
Students practice reading the statements of inequality correctly.
If necessary, review how to look at one digit in each number at a time (starting with the greatest place value) to compare the values of the numbers:
The numbers both have 4000. The number on the left has 500 and the number on the right has 600. 4,667 is more than 4,567.
2. Math Centers / Math Workout (30 min.)
Some possible activities for students to work on in centers:
ü All students complete Math Workout 2.5.8.
ü Students work on Lifework or Math Workout corrections.
ü Students work between expressing 4 digit numbers with blocks, with expanded notation, on place value mats with numerals and blocks, in standard notation.
ü Students practice showing numbers in various ways.(23 can be 2 tens and 3 ones or 1 ten and 13 ones.)
ü Students practice counting patterns (+3 and +100/+10 from any number).
ü Students practice writing numbers in basic expanded form.
ü Students practice reading and writing 4 digit numbers correctly.
ü Use the attached blank number line master. Fill in some numbers and students fill in missing values.
ü Students play a time-telling game introduced in Month 4.
ü Students practice estimating and measuring the lengths of line segments to the nearest cm and inch.
ü Students find the perimeter of various shapes either by measuring, using grid paper, or adding numbers on labeled diagrams.
ü Students find the area of rectangles drawn on grid paper.
ü Students identify what unit they would use to measure various things.
ü Students practice completing addition and subtraction number sentences. (First Grade Fact Power remediation)
ü Students draw and count lines of symmetry on shapes.
ü Students practice counting patterns.
ü Students practice counting money.
ü Practice sorting/ identifying 3-D shapes or 2-D shapes.
ü Students use 2-way mirrors to draw reflections of pictures.
ü Use geometry templates to draw, label, and count sides and corners on polygons.
ü Sort 3 dimensional blocks/ objects, polygon pattern blocks, attribute blocks, shapes on paper, and power polygons.
ü Students practice counting or writing numbers on slates with teacher guidance.
