About Adding Whole Tens and Hundreds
What this skill is
Adding whole tens and hundreds applies basic addition facts to place value multiples (30 + 40 = 70 because 3 tens + 4 tens = 7 tens).
When children learn it
Adding whole tens and hundreds is taught in 1st through 3rd grade, aligned to 1.NBT.C.4 and 2.NBT.B.8.
Teaching Tips
- Focus on the basic single-digit fact (3 + 4 = 7), then attach the trailing zero (70).
- Use base ten rod pictures to model adding tens.
Common Mistakes
- Adding trailing zeros incorrectly (writing 30 + 40 = 700).
- Misaligning place value columns when adding whole tens to 3-digit numbers.
