Max Rescues Motorcycles: Speed Addition & Subtraction!

About this Grade 1 Mixed Add Subtract Drill

At age 6 and 7, children are building the mental flexibility to switch between adding and subtracting in the same problem—a skill that feels like real "grown-up math" to them. Mixed-add-subtract problems help your child see that numbers can move in different directions and still make sense. When a child solves 5 + 2 - 3, they're learning to hold multiple steps in their mind and work left to right, which strengthens working memory and logical thinking. This foundation is crucial because all future multi-step math depends on it. In real life, kids use this every day: they earn allowance (adding), spend it (subtracting), and earn more (adding again). By practicing these mixed problems now, you're teaching your child that math is flexible and that they can handle complexity—skills that build confidence and mathematical resilience far beyond first grade.

What your student will practice

• Solve addition and subtraction problems in sequence, left to right
• Keep track of the answer after each operation before moving to the next
• Recognize when to add versus subtract based on symbols in the problem
• Build mental math speed with mixed problems using numbers to 10

Common mistakes to watch for

The most common error is that children forget the intermediate answer and restart the problem from scratch each time. For example, in 4 + 3 - 2, they'll add 4 + 3 to get 7, but then forget they have 7 and try to subtract 2 from 4 instead of from 7. Another frequent mistake is reversing the operation—reading the minus sign as plus or vice versa because they're moving quickly. You'll spot this by looking at their work: if their final answer doesn't match the symbols shown, ask them to say aloud what operation comes next. This simple check helps them slow down and self-correct.
