Max Rescues the Falling Leaves: Addition Race

About this Grade 2 Addition Drill

Addition is a cornerstone skill that Grade 2 students build on daily, both in math class and in their everyday lives. At ages 7-8, children are developing the mental flexibility to work with two-digit numbers and understand that addition involves combining groups—a concept that applies when sharing snacks, combining toy collections, or even counting the days until fall activities begin. This grade level marks the shift from concrete manipulatives (like blocks or fingers) toward more abstract thinking, where students learn addition strategies such as counting on, making tens, and recognizing number patterns. Mastering these strategies strengthens their number sense and prepares them for multi-digit addition, subtraction, and eventually multiplication. When students can add fluently and with confidence, they free up mental energy to tackle word problems and apply math to real situations. Strong addition skills also build mathematical resilience—the belief that they can solve problems through strategy and practice.

What your student will practice

• Add two-digit numbers using place value and regrouping strategies
• Fluently recall and apply basic addition facts within 20
• Demonstrate addition using mental math and multiple solution strategies
• Solve real-world addition problems presented in word form

Common mistakes to watch for

Many Grade 2 students struggle with regrouping (carrying the one) when adding two-digit numbers, often writing the full sum in the ones place instead of moving tens to the tens column—for example, writing 28 + 15 = 313 instead of 43. Others reverse the process or forget to add the regrouped ten altogether. You'll spot this pattern when a student's answer is far too large for a simple addition problem, or when they've written two digits in a single column. Watch also for students who count on their fingers from 1 each time rather than counting on from the larger number, which signals they haven't internalized efficient strategies yet.
