Concrete & Pictorial Models to Compose & Decompose Numbers to 1 200

T.I.P.S.

Students should apply their prior knowledge of place value from first grade to use objects, such as place value disks, base-ten models, or paper money, and picture models such as drawings to represent the composing, putting together, or decomposing, breaking apart, of numbers up to 1,200. Students should be able to compose and decompose these numbers into various combinations of thousands, hundreds, tens, and ones.

Example

Use a place-value chart and place value disks, base-ten blocks, or paper money to help you show the number of each of the following statements.

a)  Draw 1124 using thousands, hundreds, tens and ones.

b)  Draw 1124 using only hundreds, tens, and ones.

c)  Draw 1124 using only thousands, tens, and ones.

Hint
Possible Solution

TEKS

2.2 Number and operations. The student applies mathematical process standards to understand how to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system related to place value. The student is expected to:

(A) use concrete and pictorial models to compose and decompose numbers up to 1,200 in more than one way as a sum of so many thousands, hundreds, tens, and ones
