Max Rescues the Robot Factory: Multiply by 10!

About this Grade 2 Multiplying By 10 100 Drill

Multiplying by 10 and 100 is a foundational skill that helps second graders recognize patterns in our number system and build mental math fluency. At ages 7–8, children are developing their ability to see how numbers scale and grow, which directly supports their later work with place value, multi-digit multiplication, and even division. When students grasp that 3 × 10 = 30 or 5 × 100 = 500, they're not just memorizing facts—they're understanding how digits shift position and value. This skill appears everywhere in daily life: counting money in dimes or dollar bills, measuring distances, or organizing items into groups of tens. Fluency here builds confidence in math class and reduces anxiety around larger numbers, making future grade-level concepts feel manageable rather than overwhelming.

What your student will practice

• Recognize the pattern that multiplying by 10 adds one zero to a number
• Multiply single-digit numbers by 10 with accuracy and speed
• Multiply single-digit numbers by 100 and identify the two-zero pattern
• Apply multiply-by-10 and multiply-by-100 facts to solve word problems

Common mistakes to watch for

Many second graders add a zero without understanding *why*, leading to careless errors like writing 7 × 10 = 70 correctly but then saying 7 × 100 = 7000 instead of 700. Others confuse the direction of the pattern—thinking 10 × 3 means adding 10 to 3, rather than scaling. Watch for students who guess at the zeros instead of using a reliable strategy: if they can't explain 'I'm making the number ten times bigger,' they likely haven't built deep understanding. Ask them to show you using bundles of base-ten blocks or tallies—that concrete evidence reveals whether they truly grasp the concept.
