What Your Child Will Learn
Basic Addition Facts (K-1)
Young learners start by understanding addition as "putting together" or "combining." They use fingers, counters, and pictures to solve simple problems like 3+2=5. The goal is fluency with addition facts to 10, then to 20.
- Understand addition as combining quantities
- Use counting strategies (count on, count all)
- Recognize addition patterns (adding 0, adding 1, doubles)
- Achieve automatic recall of sums to 10
2-Digit Addition (Grades 1-3)
As students progress, they add larger numbers using place value understanding. They learn to line up tens and ones, add column by column, and "regroup" (carry) when a column sum exceeds 9.
- Add 2-digit numbers without regrouping (e.g., 23 + 45)
- Add 2-digit numbers with regrouping (e.g., 47 + 38)
- Understand place value (tens and ones)
- Use mental math strategies for compatible numbers
3-Digit & Multi-Number Addition (Grades 3-5)
Upper elementary students tackle 3-digit addition, multiple regrouping, and even adding three or more numbers in a single problem. These skills prepare them for real-world applications like budgeting and measurement.
- Add 3-digit numbers with multiple regroupings (e.g., 487 + 356)
- Add three numbers simultaneously (e.g., 23 + 45 + 67)
- Estimate sums by rounding
- Solve multi-step word problems involving addition
Teaching Addition Effectively
🧮 Use Manipulatives
Counters, blocks, or coins help young learners visualize addition. Physically combining 3 blocks with 5 blocks makes "3+5=8" concrete and understandable.
🔢 Teach Number Bonds
Show how numbers can be broken apart and recombined. Understanding that 8 = 5+3 = 6+2 = 7+1 builds number sense and mental math flexibility.
⚡ Practice Mental Strategies
Teach shortcuts like "make a ten" (7+5: think 7+3+2 = 10+2 = 12) or "add the tens first" (23+45: think 20+40=60, then 3+5=8, so 60+8=68).
📝 Daily Fluency Drills
Set a timer for 5 minutes and see how many facts students can solve. Track improvement over weeks to show progress and build motivation.
🎯 Spiral Review
Don't abandon simpler facts once students move to harder problems. Mix easy and hard on each worksheet to maintain fluency.
🌍 Real-World Contexts
Use word problems about toys, sports, food, and money. Contextual problems help students understand when to use addition in real life.
