We will have Open House on Tuesday. . .
learnzillion.com/lesson_plans/8840-read-and-write-numbers-in-expanded-form
This week in Math. . .
We will explore three different ways to express numeration. . .
STANDARD FORM
WORD FORM
EXPANDED FORM
The only form that I consider tricky (unless spelling is an issue) is Expanded Form. We will explore how this form has many varieties within its category.
Example. 1,238
1000 + 200 + 30 + 8
(1 X 1,000) + (2 X 100) + (3 X 30) + (1 X 8)
12 hundreds + 3 tens + 8 ones
38 ones + 2 Hundreds + 1 Thousand
And on and on.
I would like the students to be able to interpret numbers expressed in a variety of ways. That is my goal this week.
In addition, well, on the contrary - We truly need to review subtraction with borrowing. Many students have become rusty on this goal.
