Grade 3 - Division - Decomposition

In this video, we'll explore the decomposition strategy for division, which helps students tackle large dividends by breaking them into smaller, more manageable parts. This method allows students to work with numbers they’re more comfortable with, essentially using a reverse distributive property. By dividing these smaller parts and then adding the results together, students can find the quotient more easily.

While this strategy can be challenging, it demonstrates a strong number sense and a deep understanding of the relationship between division and multiplication.
