Max Rescues the Farm: Multiply by 10 and 100!

About this Grade 1 Multiplying By 10 100 Drill

Multiplying by 10 is a gateway skill that helps first graders see patterns in how numbers grow. When students learn that 3 × 10 = 30, they're building mental shortcuts that make math faster and less intimidating. At ages 6 and 7, children are developing number sense—the intuition that tells them whether an answer makes sense. Multiplying by 10 shows them that numbers aren't random; they follow rules. This confidence with 10s also prepares them for place value and two-digit addition, skills they'll need within months. Beyond the classroom, understanding how 10 works helps kids count money, group objects on a farm or playground, and solve small real-world problems independently. These drills cement the pattern so it becomes automatic, freeing up mental energy for harder problems.

What your student will practice

• Recognize that multiplying any number by 10 adds a zero to the end
• Fluently solve single-digit number multiplication by 10 within 100
• Explain why 4 × 10 equals 40 using place value or groups of ten
• Apply the ×10 pattern to solve word problems with groups or skip-counting

Common mistakes to watch for

First graders often write 3 × 10 = 13 instead of 30, confusing the operation of multiplying with simple addition of the digits. Another common error is forgetting the zero altogether and saying 3 × 10 = 3. You'll spot this when a child can count by 10s correctly (10, 20, 30) but doesn't connect that to the multiplication symbol. Watch for inconsistency: a student might get 2 × 10 right but then write 5 × 10 = 5, showing they haven't internalized the pattern yet, only memorized one or two facts.
