Double-Digit Addition Without Regrouping is not intended as an introduction to adding and does not include examples for beginning counters. It is intended for use as an extended addition practice tool for 1st, 2nd, and 3rd grade math students who've already been introduced to beginning addition concepts. In beginning the study of Arithmetic, the first step for students to learn is to count readily. The second step is to combine numbers. To master the different addition combinations to 20, students should be taught to write and memorize addition facts. Also when learning addition, students should avoid counting on their fingers, a habit difficult to overcome once acquired. The Double-Digit Addition Without Regrouping Workbook does not combine addition and subtraction activities. Focusing solely on addition facts gives students the advantage of strengthening addition skills before moving on to subtraction, multiplication, and division. Various addition activities have been included in this workbook in order to alleviate boredom with the addition lessons and keep students engaged as they learn. When using this workbook to teach addition, it's important to first ensure that students are comfortable with beginning addition facts. This book includes over 290 addition practice problems without regrouping: 2-Digit Addition Number Sentences; Adding 2-Digit Numbers Vertical & Horizontal; 2-Digit Addition Word Problems; 2-Digit Addition Riddle; Comparing Sums Using 2-Digit Addition; 2-Digit Addition Long Math, Vertical & Horizontal Addition; 2-Digit Long Math Addition Word Problems; The Double-Digit Math Workbook Without Regrouping is perfect for teaching addition as a precursor to students learning addition with regrouping, subtraction, multiplication, and division. The long math section introduces concepts the student will see in multiplication and division workbooks in 3rd, 4th, and 5th grade.
