Max Conquers the Soccer Stadium: Multiply by 10 Sprint!

About this Grade 2 Multiplying By 10 100 Drill

Multiplying by 10 and 100 is a foundational pattern that helps second graders begin to understand how our number system works. At age 7-8, children are developing the ability to see mathematical patterns and shortcuts—multiplying by 10 is one of the most powerful shortcuts they'll encounter. When a child recognizes that 3 × 10 = 30, they're not just memorizing; they're learning that adding a zero is a quick way to make a number ten times bigger. This skill builds mental math flexibility, prepares them for multiplication facts, and helps them handle larger numbers with confidence. In real life, kids notice this pattern everywhere—buying 10 stickers for a dollar each, or seeing that a team's 10 perfect shots in a game adds up quickly. Students who master this pattern develop stronger number sense and spend less cognitive energy on basic multiplication later.

What your student will practice

• Multiply single-digit numbers by 10 using the pattern of adding one zero
• Multiply single-digit numbers by 100 using the pattern of adding two zeros
• Apply the 10 and 100 multiplying patterns to solve word problems with real quantities
• Explain why multiplying by 10 or 100 shifts digits and changes place value

Common mistakes to watch for

The most common error is that students write the number twice instead of adding zeros—for example, writing 3 × 10 = 33 instead of 30. You'll also see children forget to add any zero at all, or add the wrong number of zeros (like 3 × 100 = 30 instead of 300). Watch for hesitation when the problem includes a multi-digit number, like 12 × 10; some second graders will add only one zero to get 12 instead of 120. Spot these mistakes by asking the student to explain what they did or by checking if their answer makes sense (Is it 10 times bigger?).
