Maths - Two digit addition with carryover - English Once first graders have mastered the Eduextrakey idea of place value and understand the concept of basic addition, moving on to two-digit addition -- both with and without regrouping -- is reasonably simple. Using manipulatives and visual cues during the learning process makes it even easier to grasp. Whether you use counting cubes, craft sticks or any other tangible items, starting two-digit addition instruction with counting tools makes later mastery less confusing. Use rubber bands to make bundles of 10 craft sticks and use them with loose singles to set up practice problems. For example, help your budding mathematician show 13 + 4 by placing a 10s bundle and three single sticks together and then adding four more single sticks before counting them all to find the sum. When she is comfortable with this practice and is successful in finding the answer consistently, she’s ready to move to a more abstract form of the problem. our child is now ready for the actual addition. Use an index card, a piece of paper or your hand to cover up the 10s column on the left. Instruct your student to add the numbers she sees in the ones column on the right and to record it under the problem, in the same column. Then, move the cover and have her add the 10s column in the same way. Show her that two-digit addition is really just two single-digit problems, once she’s lined everything up. Add 84 and 35. 1.First add the two ones' place digits (4 + 5 = 9). 2.Next add the two tens' place digits (8 + 3 = 11). 3.The sum of the ones' place digits is less than ten so the answer is 119 Add 94 and 67. 1.First add the two ones' place digits (4 + 7 = 11). 2.Next add the two tens' place digits (9 + 6 = 15). 3.The sum of the ones' place digits is a two-digit number so 4.decrease the ones' place sum by 10 (11 - 10 = 1) 5.increase the tens' place sum by 1 (15 + 1 = 16) 6.Combine the tens' and ones' place sums to give the answer of 161
