Max Rescues the Lavender Farm: Addition & Subtraction Sprint!

About this Grade 2 Mixed Add Subtract Drill

At age 7 and 8, your child is building the mental flexibility to handle problems that ask them to both add and subtract in a single equation. This is a crucial stepping stone because real life rarely presents situations in isolation—a child might earn three stickers, lose one, then earn two more. Mixed-add-subtract problems teach students to slow down, read carefully, and track what operation comes next, rather than rushing through math on autopilot. This skill strengthens working memory and number sense simultaneously, preparing them for multi-step word problems in Grade 3 and beyond. When students practice switching between + and − on the same page, they're also cementing their understanding that these operations are distinct tools, not interchangeable shortcuts. The ability to follow a sequence of operations, even with just two steps, is foundational to algebraic thinking later on.

What your student will practice

• Identify whether to add or subtract in each step of a mixed equation
• Solve two-operation problems left to right with accuracy
• Recognize and correct common errors like ignoring the second operation
• Build fluency and confidence with sums and differences up to 20

Common mistakes to watch for

The most common error Grade 2 students make is solving only the first operation and stopping—for example, seeing "8 + 5 − 3" and writing "13" without subtracting the 3. This happens because students focus so hard on the first calculation that they lose sight of the remaining work. Another frequent mistake is reversing the operation: they see a minus sign but add instead, or vice versa, especially when they're working quickly. Watch for students who write the intermediate answer but forget to use it: they calculate "7 + 4 = 11" but then treat the next part as a fresh problem rather than continuing from 11. Slow down the process and ask, "What comes next?" to catch these patterns early.
