During the Lesson: • Presentation • Processing Question • Abstraction In a grade 1, there are 18 boys and 15 girls. How many boys and girls are there in all? The boys and girls are grouped this way. Group of tens together and the ones together. Using place value chart. Given Number 18 15 Ask: • • • • • • • • Tens 1 1 Ones 8 5 How many tens are there in 18? 1 What is the place value of 1 in 18? 10 How many ones are there in 18? 8 What is the value of 8 in 18? How many tens are there in 15? 1 What is the value of 1 in 15? 10 How many ones are there in 15? 5 What is the value of 5 in 15? 5 Illustrate the response of the pupils this way. Group of 10 Group of 1 2 3 13 3 2|Page • • What have you notice in one’s column of the table? How many are there? Let us count. (13) Write 13 on the table. You can regroup the ones to gain another group of 10. You can regroup 13 ones as 1 tens and 3 ones. So, there are 3 tens in all in the total. There are 3 ones remaining after regrouping. This means that the sum of 18 and 15 is 3 tens and 3 ones or 33. C. After the Lesson: • Application Circle a group of 10. Write the new tens and ones. Then write the number. The first ones is done for you. 1. 4 tens 10 ones. Regrouping is 5 tens 0 ones or 50 2. ___ tens ____ ones. Regrouping becomes: ___ tens ____ ones or ______ 3. ___ tens ____ ones Regrouping becomes: ___ tens ____ ones or _______ • Closure Regroup to find the number then write it. The first one has been done for you. 1. 2 tens and 16 ones 2. 3 tens 6 ones 3. 8 tens and 10 ones 4. 4 tens and 19 ones 5. 2 tens and 11 ones 3|Page VI. REMARKS: VII. REFLECTION: Day 2 of 4_Days IV. V. SUBJECT MATTER: PROCEDURE A. Before the Lesson: • Review / Preparation Adding 2 -3-digit number with regrouping using expanded form. Checking of assignment Singing of Rap Song Number in the Teens (Have a Group of 10 ) A Place Value Song B. During the Lesson: Present a story word problem. • Presentation Benny has 16 balls. Danny has 19 balls. How many balls are there in all? Ask question about the story word problem. Benny Danny 16 balls 19 balls Group the tens together and ones together using place value chart. Benny Danny Tens 1 1 Ones 6 9 Using Place value chips will look like this: 4|Page How many white chips under ones place column? There are 15. Regrouping 15 means 1 ten and 5 ones. 1 ten is added to Tens Place Column and what is left under ones place is 5. It now looks like this: So, Benny and Danny have 35 balls all together. • Abstraction C. After the Lesson: • Application What can you notice when there are more than 10 in ones place column? Regroup the tens and ones. Write the number on the blank. The first one has been done for you. 1. 2. 3. 4. 5. 2 tens 6 tens 4 tens 3 tens 1 tens 15 ones 17 ones 10 ones 13 ones 19 ones _____35_______ ______________ ______________ ______________ ______________ • Closure Regroup the following. This first is done for you. 4 tens and 15 ones 3 tens and 18 ones 2 tens and 16 ones 5 tens and 11 ones 6 tens and 0 ones VI. REMARKS: VII. REFLECTION: 55 5|Page Day 3 of 4 Days I. OBJECTIVES A.

They need to read about different kind of animals. There are two shelves with books about animals. Let them count the number of books. Shelf A • Processing Question Shelf B How many books or animals are there in all? Step 1 Write the numbers in column. Align the numbers with the same place value. Tens 1 + Ones 5 4 Step 2 Add the numbers in the ones place. Tens 1 + Ones 5 4 9 Step 3 Add the tens. Tens 1 + 1 Ones 5 4 9 Present more examples. 7|Page • Abstraction How do we add one to two-digit numbers without regrouping? Align the numbers with the same place. We add these in the ones place first then those in the tens place. C. After the Lesson: • Application Answer the worksheet. • Closure Find the sum. 11 + 3 VI. REMARKS: VII.

During the Lesson: Here is the list of the number of fruits in Lola’s fruit stand. • Presentation • Processing Question 28 oranges 27 mangoes 7 watermelons 36 apples 43 bananas How many apples are there if Lina will add 7 more? Show the addition fact with the representation below. + Tens • • • 3 6 7_ Ones How many objects are there in one place column? (13) How many tens and ones are there in 13? (1) Since there are 1 group of 10 in 13, we regroup them and place 10 in the Tens Place column. Tens Ones 9|Page • • • • • Abstraction How many objects left in the ones place? (3) And how many are there in Tens Place? (4). It looks now like this: Tens Ones 4 3 What do you call the way of putting tens from the ones place? (Carrying / Regrouping) After regrouping the ten to the tens place, what should we do next? (add the tens) How many apples are there in all? (43) How do we add 1 to 2- digit numbers with regrouping? Align the numbers with the same place. We add first the ones, regroup if necessary. Group tens with other tens then add the tens to get the sum C. After the Lesson: • Application • Closure Show the sum of the following addition fact using place value chart. 34 28 37 12 53 + 29 + 56 + 49 + 78 + 29 1. Put a check (/) if the sum is correct and a cross (X) if it is not correct. If the sum is not correct, correct them. _____1. 34 + 46 = 70 _____2. 25 + 69 = 84 _____3. 29 + 63 = 92 2.
