Content Understanding Goal
Students will understand that when regrouping using a strategy that makes most sense to them, there is significance to the numbers. For instance, they will comprehend that the digit 1 can represent values such as 10, 100, or 1000.
Lesson 1:
Lesson Goal: Students will understand place value (ones, tens, hundreds, thousands) and the values of each digit

Task:  Students will be able to underline the correct digit for the desired place value

Lesson 2:
Lesson Goal: Students will understand how to express numbers in model form and then add them

Task: Students will be able to identify the amount of model blocks used in a problem to find the sum of them.
Lesson 3:
Lesson Goal: Students will use what they know about place value to write numbers in expanded form and add them whether it’s in a numberline or stacked on top of each other like the standard algorithm
Task: Students will be able to write the numbers in expanded from using the appropriate amount of digits and zeros in a number

Lesson 4:
Lesson Goal: Students will add numbers using the standard algorithm, making sure they are stacking their numbers up one on top of each other 
Task: Students will be able to show their work and answer why they have 1’s on top of their problem

Lesson 5:
 

Lesson Goal: Students will understand that when adding numbers that equal more than 10, they will need to regroup 

Task: Students will be able to explain what regrouping is and talk through their strategies to demonstrate the significance of the numbers.
