Grade 4 - Division - Decomposition

In this video, we explore the decomposition strategy for division, a method that simplifies division by breaking the dividend into more manageable numbers. We demonstrate how to divide 188 by 4 by decomposing 188 into 100 and 88, which can be easily divided.

The strategy is particularly effective when students can identify numbers that can be broken down into easier parts, often based on place value. This approach is like a reverse application of the distributive property and helps students handle division with larger numbers more confidently.
