In this lesson, students solve "put together/take apart with addend unknown" word problems such as, "Maria has 15 baseballs. 8 of them are old, and some of them are brand new. How many brand-new baseballs does Maria have?" Students solve these problems using both the "counting on" strategy and more advanced subtraction strategies.- Aligned Standards
