### 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

Differentiated work toward mastery of Month 5 standards.
