Max Rescues the Circus Animals: Multiply by 10!

About this Grade 1 Multiplying By 10 100 Drill

Multiplying by 10 is one of the first big shortcuts young mathematicians discover, and mastering it opens doors to understanding place value and number patterns. At ages 6-7, children are developing their ability to recognize that 3 × 10 always equals 30—not through repeated counting, but through recognizing a reliable pattern. This skill builds number sense, which is the foundation for all future multiplication and helps children see math as logical rather than random. When a child understands that adding a zero means "making groups of 10," they're not just memorizing; they're thinking like a mathematician. This worksheet gives your child repeated, low-pressure practice so the pattern becomes automatic. You'll notice them naturally applying this shortcut when solving word problems or counting money—skills they use in real life, from organizing toys to thinking about time at school.

What your student will practice

• Recognize that multiplying any single-digit number by 10 adds one zero
• Solve multiplication by 10 problems fluently without counting on fingers
• Apply the multiply-by-10 pattern to solve one-step word problems
• Explain why 5 × 10 equals 50 using groups or place value language

Common mistakes to watch for

The most common mistake is when children add the zero but forget which number it attaches to—for example, writing 3 × 10 = 03 instead of 30, or randomly placing zeros. Another frequent error is children who haven't grasped the pattern yet will try to count by ones or use their fingers repeatedly instead of applying the shortcut. You can spot this by watching whether they pause and count laboriously or instantly recognize the pattern. If a child consistently writes numbers backward or in the wrong place, it often signals they haven't internalized that the zero goes on the right side, not the left.
