Learn on PengienVision, Mathematics, Grade 4Chapter 3: Use Strategies and Properties to Multiply by 1-Digit Numbers

Lesson 1: Multiply by Multiples of 10, 100, and 1,000

Property.

Section 1

Strategy 1: Use Unit Form

Property

To multiply by a multiple of 10, 100, or 1,000, you can express the multiple in unit form. For example, think of 4040 as 44 tens, 400400 as 44 hundreds, and 4,0004,000 as 44 thousands.

Examples

Section 2

Strategy 2: Applying the Associative Property

Property

The Associative Property of Multiplication states that you can change the grouping of factors without changing the product.

(a×b)×c=a×(b×c)(a \times b) \times c = a \times (b \times c)
