 Our lesson in math today is addition. Kids, what do you think? Shall we have more or shall we have less when we add? Let's try to find out. Have a look of this sample. One apple plus one apple equals two apples or one plus one equals two. So when we add, we can see that we have more. Look at this addition sentences. One plus one equals two. Two plus two equals four. Four plus four equals eight. Notice that the sums show greater numbers. So it means when we add, we have more. This is an addition sentence. Three plus two equals five. We call the numbers that we add together add ends. The answer in addition is called sum. We use the plus sign when we add. Numbers can be added in two ways. Horizontally, four plus five equals nine. The add-ins are four and five. The sum is nine. Vertically, four plus five equals nine. Still, the add-ins are four and five. And the sum is nine. Now let's do some drills in addition. One plus three equals four. Three plus three equals six. Four plus one equals five. Five plus three equals eight. With that object, you can also use your fingers in addition. Three plus four equals seven. Zero plus five equals five. Two plus two equals four. Five plus four equals nine. Five plus five equals ten. Find the sum. Five plus two equals seven, right? Six plus one equals seven, right? Four plus eight equals twelve, right? Now kids, do the addition drills in your book. Good luck!
