Mastering Making 10 Addition Strategy: Core Concepts & Mental Models
The Making 10 strategy is one of the most powerful mental math foundations in early elementary arithmetic. Rather than counting on fingers one-by-one, students decompose numbers to bridge to the friendly benchmark number 10.
๐ก Essential Strategies for Making 10 Addition Strategy
๐ฏ Identify the Anchor Addend
Look for the number closest to 10 (like 9, 8, or 7). Determine how many more are needed to reach 10.
โ๏ธ Decompose the Second Addend
Split the other number into two parts: the exact partner needed to make 10, and whatever amount is left over.
โก Add Friendly 10 + Leftover
Combine the anchor with its partner to make 10, then effortlessly add the remainder (e.g. 10 + 3 = 13).
โ ๏ธ Common Mistakes & Teacher Fixes
Why students stumble: Students may split 5 into 1 and 4 when working with 8, forgetting that 8 needs 2 to make 10.
๐ Key Mathematical Vocabulary
Decompose
To break a number apart into smaller parts (e.g., breaking 5 into 2 + 3).
Benchmark 10
The foundational base-ten number 10, which makes adding any single-digit remainder immediate and error-free.
Associative Property
Regrouping addends without changing the sum: (8 + 2) + 3 = 10 + 3 = 13.
โ Frequently Asked Questions
How do you solve a making 10 addition strategy problem step by step?
Here is a worked example: "Solve 8 + 5 using the Making 10 Strategy:". Solution: 1. 8 needs 2 to make 10. 2. Split 5 into 2 + 3. 3. (8 + 2) + 3 = 10 + 3 = 13. Answer: 13.
What is the core learning objective for making 10 addition strategy?
Add numbers within 20 by decomposing the second addend to make a ten first (e.g., 8 + 5 = 8 + 2 + 3 = 10 + 3 = 13). This directly aligns with Common Core Standard CCSS.MATH.CONTENT.1.OA.C.6.
What is the most common mistake students make with making 10 addition strategy?
A frequent pitfall is: "Decomposing the wrong amount from the second addend". Why students stumble: Students may split 5 into 1 and 4 when working with 8, forgetting that 8 needs 2 to make 10. How to fix it: Always ask first: 'How many more does the anchor number need to reach 10?' Write that number down first. (Example: For 8 + 5: 8 + 2 = 10, so 5 must be split into 2 and 3.)
