TEN POWER
Mastering the Make-a-Ten Strategy
Our Mission
We want to add big numbers fast. Adding to 10 is easy, so let's use that!
Why use 10?
- \(10 + 2 = 12\) (Fast!)
- \(10 + 5 = 15\) (So Easy!)
- \(10 + 8 = 18\) (You got it!)
10
Step-by-Step Power
Example: \(9 + 4\)
1
Fill the Gap
9 is so close to 10. It only needs 1 more.
9 + ?
2
Decompose
Break 4 into 1 and 3. Give the 1 to 9!
9 + (1 + 3)
3
Final Jump
\(10 + 3 = 13\). Fast and simple!
10 + 3 = 13

SOLVE: \(8 + 5\)
8 needs 2
5 splits into 2 & 3

10 + 3 = 13

Lesson: Number Neighbors | Grade 1
45-60 MIN
Instructional Goal
Students will use the "Make a Ten" strategy to solve addition problems within 20 by decomposing a smaller addend to reach a benchmark of 10.
Essential Questions
Materials Needed
- Double Ten-Frame Mats
- Two-color counters
- "Strategy Sprint" Sheets
- 10-sided dice (or 1-9 dice)
- Missing Neighbor Cards
The Game Plan
1
Direct Instruction: Ten Power (15 min)
Use the Ten Power Slides to model the strategy. Focus on the language of "breaking apart" the second addend. Key prompt: "If I have 9, how many more do I need to make a full ten? Where can I get that 1 from?"
2
Small Group Game: Missing Neighbor Match (15 min)
Students play in pairs using the Missing Neighbor Cards. One student shows a card like "8 + __ = 10". The partner must find the 'Missing Neighbor' (2) to complete the set. This reinforces the benchmark of 10.
3
Guided Practice: Strategy Sprint (15 min)
Students use dice to generate problems. They must use the Double Ten-Frame Mat to visually move counters to "Make a Ten" before recording the final sum on their Strategy Sprint Sheet.
Teacher Tips & Misconceptions
Common Pitfall
Students may forget to subtract the "borrowed" amount from the second addend (e.g., doing \(9+4\) as \(10+4\) instead of \(10+3\)).
The Fix
Always use two different colored counters. This makes it visually obvious that the piece was moved from one frame to the other, not added from thin air.
Support
Provide cards that already have the ten-frames partially filled. Focus solely on 9 + __ and 8 + __ before moving to 7 or 6.
Extend
Challenge students to solve subtraction problems like \(14 - 6\) using the "Back to Ten" strategy (\(14 - 4 = 10\); \(10 - 2 = 8\)).
