Jack is collecting eggs from his family's chicken coop. He found 18 eggs yesterday and 21 eggs today. How many eggs did Jack collect in total? How many eggs did Jack collect yesterday? How about today? Did Jack collect the same number of eggs yesterday and today? When did he collect fewer eggs? When did he collect more eggs? What does the problem want us to do? Let us read the problem together and let us solve this together. Sophie collected 8 leaves. Nora collected 24 leaves. How many more leaves does Sophie need to collect to have the same number as Nora? Sophie’s leaves Nora’s leaves Counted 8 and 24 counters for the leaves collected by Sophie and Nora. Eight were removed from 24. Sixteen remained. Sophie should collect 16 more shells. By finding the missing addend, 8 + 16 = 24 Sophie has to collect sixteen more leaves so that they both have the same number of leaves. How many leaves did Sophie collect? How many leaves did Nora collect? What does the problem want us to do? Sophie has 8 leaves while Nora has 24 leaves. The problem asks for the additional number of leaves Sophie must collect to have the same number of leaves as Nora. Explain what this addition number sentence means, and give the missing number. 12 + ___ = 26 Eight tells the number of leaves collected by Sophie. Twenty-four tells the number of leaves collected by Nora. The blank tells the number of leaves Sophie needs to collect so that she will have the same number of leaves as Nora. What number should be in the blank so that Sophie will have the same number of leaves as Nora? How many more leaves should Sophie collect to have the same number of leaves as Nora? How did you get 16 the number of leaves Sophie needs to collect? Practice at home.  MATH 1 Adding 3 or More D Addends with Sums Up A to 100 Without Regrouping QUARTER 2 WEEK 8 Y Answer the following addition number phrases on your show-me- board. 3 + 7 + 3 6 + 5 + 4 5 + 2 + 3 9 + 4 + 6 5 + 3 + 7 To add 3 addends with sums up to 100 without regrouping  add, plus, addends, sum The table below shows the number of toy cars collected. What is the table about? How many toy cars were collected by Mark? How many toy cars were collected by Simon? How many toy cars were collected by James? Who collected the greatest number of toy cars? Who collected the least number of toy cars? What are the addends in each addition number sentence? How many addends are there in each addition number sentence? How many addends are there in the addition number sentence? How did you add the three addends?  Observe the algorithm for adding numbers. The addends were added two at a time. Adding the digits in the ones place (2 addends at a time) first. Then, add the digits in the tens place (2 addends at a time). Both ways give the same sum. However, the second procedure is more effective than the first one. Use your show-me-board to answer these. 31 + 12 + 42 = ___ 33 + 41 + 5 = ___ 62 + 3 + 32 = ___ 41 + 22 + 11 +1 3 = ___ 11 + 12 + 15 = ___ How do you add three or more addends? Write in columns and add. 1) 22 + 15 + 12 2) 34 + 22 + 11 3) 45 + 13 + 20 4) 2 + 25 + 41 5) 30 + 14 + 22 + 3 Practice at home.  MATH 1 Solving and Creating D Problems Involving the A Addition of Whole Numbers QUARTER 2 WEEK 8 Y Try adding more than 2 addends. 23 + 12+ 12 62 + 24 + 11 11 + 20 + 8 5 + 40 + 22 20 + 15 + 12 + 12 To create and solve problems involving addition of whole numbers  add, plus, addends, sum Four cousins picked guavas. The number of guavas each child picked is shown in the table.  What is the table about?  What are the names of the cousins?  Did they pick the same number of guavas?  Who picked the greatest number of guavas?  How many guavas did Sandra pick? Now it is your turn to think of a question about the information presented in the table. How did you create the questions? How did you solve the questions? Answer each question. The table below shows the number of Shirts collected. 1. What is the table about? 2. How many shirts were collected by Francis? 3. Who collected the greatest number of shirts? 4.
