Count bundles of 10 and loose sticks to add two-digit numbers
Name:
Date:
Key:
10 1 Bundle = 10 sticks (1 Ten)
•
1 Single Stick = 1 stick (1 One)
Add Tens first, then Ones!
Guided Model Example Look how we count bundles, then singles:
10 10
24 sticks
10
13 sticks
Tens (bundles): 2 + 1 = 3 tens (30)
Ones (singles): 4 + 3 = 7 ones (7)
Equation: 24 + 13 = 37
1 Count the sticks in each group, then add:

3 Story Challenge: Craft Time!
Find the Grand Total
Sam collected 2 bundles of 10 and 5 loose sticks. Maya collected 2 bundles of 10 and 4 loose sticks. How many popsicle sticks do they have in all?

Topic: 2-Digit Addition (Tens & Ones)
Standard: CCSS Math 1.NBT.C.4 & 2.NBT.B.5
Worksheet Solutions Guided Model: 24 + 13 = 37 (2 tens + 1 ten = 3 tens; 4 + 3 = 7 ones)
1 Problem 1 32 + 15
Groups Counted:
Group A: 32 (3 tens, 2 ones)
Group B: 15 (1 ten, 5 ones)
Bundles: 3 + 1 = 4 tens (40)
Singles: 2 + 5 = 7 ones (7)
Final Equation & Sum
32 + 15 = 47
2 Problem 2 16 + 23
Groups Counted:
Group A: 16 (1 ten, 6 ones)
Group B: 23 (2 tens, 3 ones)
Bundles: 1 + 2 = 3 tens (30)
Singles: 6 + 3 = 9 ones (9)
Final Equation & Sum
16 + 23 = 39
3 Problem 3 25 + 24
Story Characters:
Sam: 25 (2 tens, 5 ones)
Maya: 24 (2 tens, 4 ones)
Bundles: 2 + 2 = 4 tens (40)
Singles: 5 + 4 = 9 ones (9)
Total Popsicle Sticks
25 + 24 = 49
Exit Ticket Quick Check Solution Target Equation: 31 + 26 = 57 Sticks
1. Count Bundles (Tens): 3 bundles + 2 bundles
3 + 2 = 5 tens (50)
2. Count Singles (Ones): 1 stick + 6 sticks
1 + 6 = 7 ones (7)
3. Addition Equation: Total sticks combined
31 + 26 = 57
3-Point Scoring Rubric:
- 1 Point: Correct tens counted (3 + 2 = 5 bundles)
- 1 Point: Correct ones counted (1 + 6 = 7 singles)
- 1 Point: Accurate equation (31 + 26 = 57)
Diagnostic Notes & Differentiation Strategies Support for Emerging Learners
Reversing Place Value
Students write 23 instead of 32 for 3 bundles and 2 singles. Prompt: "Which number counts the groups of 10? That goes first!"
Hands-On Concrete Support
For struggling students, provide real wooden craft sticks and small rubber bands. Have them physically build and combine the bundles on a Place Value Mat.
Fast-Finisher Extension
Ask: "If you added 1 more bundle of 10 to Problem 3, what would the new total be?" (59 sticks). Challenges mental addition by 10.
