3rd Grade Addition and Subtraction to 10,000: Part-Whole Strategy Worksheets

What students practice

Seven pages each teach one part-whole strategy for 4-digit addition and subtraction: add by place, jump forward, jump back, make a friendly number, count up to subtract, parts and whole, and group friendly numbers. One fluency page works within 1,000 with any strategy. Then a letter stands for the unknown, and two pages of story problems ask for an equation with a letter, a solution, and a check. There is no column algorithm anywhere in the packet; every strategy breaks the numbers into place value pieces.
