### PRODUCT DESCRIPTION

**TeachableMath.com**

**This free product is a preview to our 47-page Singapore Math 1st and 2nd Grade Addition and Subtraction (numbers to 100) with Regrouping.**

***************************************************
This is a set of worksheets for 1st & 2nd Grade Addition and Subtraction with regrouping, for numbers to 100, aligned to Common Core standards (2.NBT).

The Common Core encourages learners to explore multiple ways to solve a common problem and find strategies that fit their learning style. To promote deeper learning, this worksheet set uses a variety of addition and subtraction strategies commonly found in Singapore Math, including number bond, place value chart and standard algorithm. Through these exercises, students acquire conceptual knowledge (why the rules work), in addition to procedural knowledge (what are the rules). Teachers and parents, who are familiar with the studentâ€™s learning style, can choose the appropriate activities for both conceptual and procedural learning.
