Teacher Script: Math Facts: Add 'Em Up!

Warm-Up: Fact Recall Race (5 minutes)

"Good morning/afternoon, mathematicians! Welcome to Math Facts: Add 'Em Up! Today, we're going to become even faster and more confident with our addition and subtraction facts. To get our brains warmed up, let's start with a 'Fact Recall Race'!"

"I'm going to flash some addition and subtraction facts on the board from our Math Facts Slide Deck. Your job is to solve them as quickly as you can. You can whisper the answer, or if you have a small whiteboard, you can write your answer and show it when I say 'Show me!' Ready? Let's go!"

(Display Slide 1 from Math Facts Slide Deck. Flash simple facts one by one, encouraging quick responses.)

Mini-Lesson: Strategies for Speed (10 minutes)

"Fantastic job, everyone! You're already showing off your amazing math brains. Now, sometimes, when a fact doesn't immediately pop into our heads, we can use some clever strategies to figure it out quickly. We're going to review a few of those now."

"First, let's look at Strategy 1: Counting On (or Back!)."
(Display Slide 2 from Math Facts Slide Deck)
"When you're adding, especially a small number, you can start with the bigger number and count on. For example, for 8 + 3, you can start at 8 and count on three: 9, 10, 11. So 8 + 3 equals 11. Who can give me another example of counting on?"

"And for subtraction, you can count back. For 9 - 2, start at 9 and count back two: 8, 7. What about 7 - 3? How would you count back?"

"Next up, Strategy 2: Doubles & Near Doubles!"
(Display Slide 3 from Math Facts Slide Deck)
"We all know our doubles, right? Like 4 + 4 = 8, or 7 + 7 = 14. These are super helpful! But did you know you can use them for 'near doubles' too? If you know 4 + 4 = 8, then 4 + 5 is just one more, so it's 9! Or if 7 + 7 = 14, then 7 + 8 is 15. It's like a math superpower! Can anyone think of a near double for 6 + 7?"

"And finally, Strategy 3: Fact Families!"
(Display Slide 4 from Math Facts Slide Deck)
"Fact families show us how addition and subtraction are related, like brothers and sisters! If you know 3 + 5 = 8, then you automatically know 5 + 3 = 8, 8 - 3 = 5, and 8 - 5 = 3. They all use the same three numbers! Look at the example on the board: 6, 4, and 10. What are all the fact family equations for these numbers?"

"To help us visualize these strategies even better, let's watch a quick video!" (Display Slide 5 from Math Facts Slide Deck and play the video.)

Practice Time: Worksheet Whirl (10 minutes)

"Excellent watching, everyone! Now it's time to put our amazing strategies into action. I'm handing out a Fact Fluency Worksheet. Your mission, should you choose to accept it, is to complete as many problems as you can, using the strategies we just discussed to help you. Focus on accuracy and try to get a little faster as you go!"

(Distribute the Fact Fluency Worksheet. Circulate the room, offering individual support, asking students what strategies they are using, and checking for understanding.)

"If you finish early, you can double-check your answers or try to create your own fact families!"

Quick Check: Quiz Time! (5 minutes)

"Alright, mathematicians, great effort on the worksheet! To wrap up our lesson and see how much your brains have grown today, we're going to do a super quick quiz. This helps me see what we've mastered and what we might need to practice a bit more."

(Collect the worksheets and distribute the Math Facts Quiz.)

"Please complete this quiz independently. Do your best, read each question carefully, and remember the strategies we talked about. When you're finished, please turn your quiz over. I'll collect them all at the end."

(Allow students to complete the quiz. Collect the quizzes.)

"Wonderful work today, everyone! You all did a fantastic job practicing your math facts and using those clever strategies. Keep practicing, and you'll be math fact superstars in no time!"

Fact Fluency Worksheet: Answer Key

This answer key provides the correct solutions and brief explanations for the problems on the Fact Fluency Worksheet.

Addition Facts

1. 4 + 5 = 9
   Thought Process: Start at 5, count on 4: 6, 7, 8, 9.
2. 7 + 3 = 10
   Thought Process: Start at 7, count on 3: 8, 9, 10.
3. 9 + 2 = 11
   Thought Process: Start at 9, count on 2: 10, 11.
4. 6 + 6 = 12
   Thought Process: This is a double fact. 6 and 6 make 12.
5. 8 + 5 = 13
   Thought Process: Start at 8, count on 5: 9, 10, 11, 12, 13.
6. 10 + 4 = 14
   Thought Process: Adding to 10 is often easy! 10 and 4 is 14.
7. 3 + 9 = 12
   Thought Process: Use the commutative property (order doesn't matter) and count on from 9: 10, 11, 12.
8. 7 + 8 = 15
   Thought Process: This is a near double. 7 + 7 = 14, so 7 + 8 is one more: 15.
9. 2 + 11 = 13
   Thought Process: Count on from 11: 12, 13.
10. 5 + 7 = 12
    Thought Process: Count on from 7: 8, 9, 10, 11, 12.

Subtraction Facts

11. 12 - 3 = 9
    Thought Process: Think: 3 + ? = 12. 3 + 9 = 12, so 12 - 3 = 9.
12. 10 - 5 = 5
    Thought Process: This is a double fact. 5 + 5 = 10, so 10 - 5 = 5.
13. 15 - 7 = 8
    Thought Process: Think: 7 + ? = 15. Count on from 7 to 15: 8, 9, 10, 11, 12, 13, 14, 15 (that's 8).
14. 11 - 4 = 7
    Thought Process: Think: 4 + ? = 11. Count on from 4 to 11: 5, 6, 7, 8, 9, 10, 11 (that's 7).
15. 9 - 6 = 3
    Thought Process: Think: 6 + ? = 9. Count on from 6 to 9: 7, 8, 9 (that's 3).
16. 13 - 8 = 5
    Thought Process: Think: 8 + ? = 13. Count on from 8 to 13: 9, 10, 11, 12, 13 (that's 5).
17. 16 - 9 = 7
    Thought Process: Think: 9 + ? = 16. Count on from 9 to 16: 10, 11, 12, 13, 14, 15, 16 (that's 7).
18. 8 - 2 = 6
    Thought Process: Count back from 8: 7, 6.
19. 14 - 6 = 8
    Thought Process: Think: 6 + ? = 14. Count on from 6 to 14: 7, 8, 9, 10, 11, 12, 13, 14 (that's 8).
20. 17 - 8 = 9
    Thought Process: Think: 8 + ? = 17. Count on from 8 to 17: 9, 10, 11, 12, 13, 14, 15, 16, 17 (that's 9).

Challenge! Fact Families

Numbers: 5, 6, 11

• 5 + 6 = 11
• 6 + 5 = 11
• 11 - 5 = 6
• 11 - 6 = 5
  Thought Process: A fact family uses three numbers to create two addition and two subtraction equations. Ensure all three numbers are used in each equation.
