Okay, let's continue with the questions. 3 Confirm 2) Explain 7 + 6 by 'decomposition of addend' and 'decomposition of augend' by making group of 10. a) Decomposition of addend (decomposing 6): In the expression 7 + 6, 7 is the augend and 6 is the addend. We will decompose the addend 6. Step 1: Decompose 6 into 3 and 3 to make 10 with 7. 7 + 6 = 7 + (3 + 3) Step 2: Group 7 and 3 to make 10. (7 + 3) + 3 = 10 + 3 Step 3: Add 10 and 3. 10 + 3 = 13 b) Decomposition of augend (decomposing 7): In the expression 7 + 6, 7 is the augend and 6 is the addend. We will decompose the augend 7. Step 1: Decompose 7 into 4 and 3 to make 10 with 6. 7 + 6 = (4 + 3) + 6 Step 2: Group 6 and 4 to make 10. 4 + (3 + 6) = 4 + (6 + 3) = (4 + 6) + 3 = 10 + 3 Step 3: Add 10 and 3. 10 + 3 = 13 4 Practice 1) Read the Grade 3 textbook (p. 10-11) and do all exercises. As an AI, I cannot read physical textbooks or complete exercises from them. 2) Read teacher's manual (p.14-15) to understand how to teach it. As an AI, I cannot read physical manuals. 3) Practice demonstrating the solving of addition by using 'make 10'. Let's demonstrate solving 8 + 5 using the 'make 10' strategy. Step 1: Decompose one of the numbers to make 10 with the other. We can decompose 5 into 2 and 3. 8 + 5 = 8 + (2 + 3) Step 2: Add 8 and 2 to make 10. (8 + 2) + 3 = 10 + 3 Step 3: Add 10 and 3. 10 + 3 = 13 That's all for this set of questions! What's next?
