Max Rescues Lost Whales: Addition Sprint!

About this Grade 2 Addition No Regrouping Drill

At age 7 and 8, students are building the mental math foundation they'll use for their entire academic career. Addition without regrouping—sometimes called addition without carrying—helps second graders see that math is logical and predictable. When your child adds 23 + 14, they're learning to break numbers into tens and ones, which is crucial for understanding place value. This skill also builds confidence because students can solve these problems without the extra cognitive load of carrying, letting them focus on the core concept of combining groups. Mastering no-regrouping addition makes harder problems feel manageable later on. Right now, your child is developing the number sense that lets them estimate costs at a store, combine scores in games, or count supplies—skills they'll use every single day.

What your student will practice

• Add two 2-digit numbers with no regrouping accurately
• Align numbers correctly by place value in columns
• Apply the strategy of adding ones column first, then tens
• Recognize when a problem requires no regrouping

Common mistakes to watch for

The most common error second graders make is misaligning digits when writing problems vertically—putting the 3 in 23 under the 4 in 14 instead of stacking tens above tens and ones above ones. You'll spot this if their answers are wildly off, like getting 37 when adding 23 + 14. Another frequent mistake is adding across instead of down: they'll add 2 + 1 to get 3, then add 3 + 4 to get 7, writing 37 instead of correctly getting 37 through place value. Some students also forget to write the tens digit in their answer, writing just 7 instead of 37.
