The Teen Bridge
14 = 10 + 4
Teen numbers are made of one full ten and some extra ones!
First Ten-Frame (Full 10)
Second Ten-Frame (4 Extra)
Let's Break Down 14
- 1 How many complete tens? 1 ten (10)
- 2 How many leftover ones? 4 ones
- 3 Putting them together: 10 + 4 = 14
Fourteen is just ten with four more!
Focus: Visualizing numbers as 10 and leftovers Slide 2 of 6

10 + 7 = 17 1 ten and 7 ones
Let's count! Point to each block on the left and count from 1 to 17 together. Ready? Go!
Goal: Understand multiple models of representation Slide 3 of 6
Partner Talk Challenge
Marshmallow Mystery
Think, Pair, Share!
"Sam brought 13 marshmallows to the campfire. He roasted some of them. Now he only has 5 left."
How many marshmallows did Sam roast?
Camp Buddy Prompts:
- What number do we start with? Is it bigger or smaller than 5?
- Can you count back from 13 to 5? Let's try it!
Visual Mystery Board
We have:
13 total minus ? roasted equals 5 left
Tip: Draw 13 circles. Cross out circles until you have exactly 5 left. Count how many you crossed out!
Let's talk with your neighbor!
Goal: Model word problems using subtraction/counting strategies Slide 4 of 6
Guided Modeling
Starry Night Problems
Addition Strategy
"Campers looked up and counted 9 stars in the sky. Then, the clouds cleared and they saw 6 more stars."
How many stars did they see in total?
Equation 9 + 6 = [ ? ]
Camp Counselor Strategy: "Make a Ten"
1
Start with the bigger number: 9 stars
2
Borrow 1 from the 6 to make ten: 9 + 1 = 10
3
Add the leftovers: 10 + 5 = 15
They saw 15 stars in total!
Goal: Solve addition word problems by bridging to ten Slide 5 of 6

Campfire Reflection
Let's Show Our Skills!
Amazing work today, math campers! Before we break for math centers, let's test our understanding on one last mystery number.
Your Challenge:
How would you represent the number 19?
- Using a double ten-frame
- Using base-ten blocks (tens & ones)
- Using tally marks
