 Hi kids, our lesson for today is about addition problems. Addition work problems arise in any situation where there is a gain or an increase of something as a result of combining two or more numbers. It is very important to know the given number facts in the problem so that we can figure out the addends in the number sentence. And when we add the addends, then we find the sum. Then we can say that we have already solved the addition problem. Now let's try to solve addition problems in your book. There are three roses and five daisies in a flower vase. How many flowers in all are there in the vase? The given number facts are three and five. Three plus five equals eight. So there are eight flowers in the vase. Jack eats two big buns and three small buns. How many buns in all does Jack eat? The given number facts are two and three. Two plus three equals five. Jack eats five buns. In a birthday party, there were four blue balloons and six red balloons. How many balloons in all were there? The given number facts are four and six. Four plus six equals ten.
