The document discusses different methods for adding whole numbers, including adding columns separately by adding the numbers in the hundreds, tens, and ones places individually and then combining the results. It provides examples of adding two numbers using these column addition and reverse order addition methods. The document also includes practice problems for students to practice different addition methods and check their work.

1. Lesson 4<br />DIFFERENT METHODS IN ADDING WHOLE NUMBERS<br /> Objectives: <br />After this lesson, the students are expected to:<br />solve addition using other methods;<br />discuss the different methods in adding whole numbers;<br />solve mathematical problems using the other method.<br />There are some easy ways in adding whole numbers.<br /> Adding the column separately. Let 326+258 use as our illustrative example.<br />422021043815<br />Adding in reverse order<br />326 300+20+6<br /> +258 200+50+8<br />Add the numbers in the hundreds place.Add the numbers in the tens place.Add the numbers in the ones place.Then add their sum to get the total sum. 500<br />300+20+6<br />200+50+8 500+70<br />300+20+6200+50+8 500+ 70+14<br />500+70+14=584Adding in column separately<br />389692160679EXAMPLE: <br /> 526<br /> + 278 <br /> 14<br /> + 9<br /> 7<br />Arrange the numbers vertically.Add the numbers in the ones place.Then add the tens place and place the sum under the tens place.Then add the numbers in column. 804<br />Tocheck;<br />Add it upward.<br />Subtract the sum to one of the addends.<br />Add the numbers in the addends and in the sum if your answer in the sum is the same as in the addends, then your answer is correct.<br />-479127-394796WORKSHEET NO. 4<br />-42100503688715NAME: ___________________________________DATE: _____________ <br />YEAR & SECTION: ________________________RATING: ___________<br />19051-3913<br />Using any of the given ways, add the following and write the answer in the space provided.
