Lesson Introduction Video
- This short, animated introduction video would start by posing a problem for the students.
- Sample Problem: The workers at Pizza Planet sold 228 pizzas on Saturday. They sold 134 pizzas on Sunday. How many pizzas did they sell on both days?
- The narrator would then explain that this problem can be solved using addition. (228 + 134 = _____)
- The narrator would state that place value models can help us add bigger numbers.
- Using animated place value models, the narrator would demonstrate how to show each number using place value. (228 as 2 hundreds, 2 tens, 8 ones and 134 as 1 hundred, 3 tens, and 4 ones)
- Then, the narrator would add the place value models together. (3 hundreds, 5 tens, 12 ones)
- Next, the narrator would demonstrate how to regroup using the place value models. (3 hundreds, 6 tens, 2 ones)
- Finally, the narrator would give the answer to the problem, while it is shown both as a number sentence and place value models on the screen. (228 + 134 = 362)
