Instruction/Activity

1. Identify and generate equivalent forms of whole

numbers; e.g., 36, 30 + 6, 9 x 4, 46 - 10, number of inches

in a yard.

Concentration
Match numbers, shapes, fractions, or multiplication facts to equivalent representations.

http://illuminations.nctm.org/ActivityDetail.aspx?ID=73

2. Use place value concepts to represent whole numbers

and decimals using numerals, words, expanded notation

and physical models. For example:

a. Recognize 100 means “10 tens” as well as a single

entity (1 hundred) through physical models and

trading games.

b. Describe the multiplicative nature of the number

system; e.g., the structure of 3205 as

3 x 1000 plus 2 x 100 plus 5 x 1.

c. Model the size of 1000 in multiple ways; e.g., packaging

1000 objects into 10 boxes of 100, modeling a meter

with centimeter and decimeter strips, or gathering

1000 pop-can tabs.

d. Explain the concept of tenths and hundredths using

physical models, such as metric pieces, base ten

blocks, decimal squares or money.
