Max Conquers the Roman Colosseum: Addition and Subtraction Sprint!

About this Grade 2 Mixed Add Subtract Drill

At age 7 and 8, your child is building the mental flexibility needed to handle problems where they add and subtract in the same problem. This skill moves them beyond simple, single-operation math into the real world, where we constantly shift between gaining and losing. When a child buys snacks with pocket money, receives birthday gifts, and spends allowance, they're practicing mixed operations without realizing it. Grade 2 mixed-add-subtract work strengthens working memory—the ability to hold multiple steps in mind—and develops number sense that becomes the foundation for multi-digit computation and word problems in later grades. Students who master this now approach more complex math with confidence rather than anxiety. These drills train automaticity, so children can solve mixed problems fluently without counting on their fingers, freeing up mental energy for problem-solving strategy.

What your student will practice

• Solve mixed-add-subtract problems with accuracy in the correct left-to-right order
• Recognize when to switch operations and apply the correct symbol
• Build fluency with two-step calculations within numbers 0–20
• Apply mixed operations to simple word-problem contexts

Common mistakes to watch for

The most common error is when students solve only the first operation and ignore the second. For example, given 5 + 3 − 2, they'll stop at 5 + 3 = 8 and write 8 as their final answer. Another frequent pattern is reversing the order—subtracting first when they should add, or vice versa, because they focus on the operation symbol closest to them rather than reading left to right. Watch for students who recount from the beginning for every step instead of using their first answer to start the next calculation; this is slow and error-prone. If your child circles only one operation or skips the second step entirely, slow down and have them point to each symbol before solving.
