Description: One of a series of documents describing the progression of a topic across several grade levels, informed both by research on children's development and by the structure of mathematics. Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. Students use standard algorithms to fluently add and subtract. They use methods based on place value and properties of operations supported by suitable representations to multiply and divide with multi-digit numbers.*Teacher Advisor is 100% free.
