Max Rescues the Lost Concert: Multiplication Race!

About this Grade 1 2 Digit By 1 Digit Drill

At age 6 and 7, students are building the mental math foundation that will support all future arithmetic. Two-digit-by-one-digit multiplication (like 12 × 3 or 23 × 2) teaches children to break larger numbers into manageable parts—a skill that develops flexible thinking and number sense. When a child multiplies 15 × 2, they're learning to see 15 as "ten and five," then multiply each part separately. This decomposition strategy is crucial because it connects to real-world situations: buying multiple packs of crayons, counting coins in groups, or figuring out how many minutes in several hours. Mastering these problems builds confidence with two-digit numbers and lays the groundwork for division, fractions, and multi-digit multiplication in later grades. It also strengthens the brain's ability to hold and manipulate information—a core cognitive skill for this age.

What your student will practice

• Multiply two-digit numbers by one-digit numbers using arrays or skip-counting
• Decompose two-digit numbers into tens and ones before multiplying
• Solve word problems requiring two-digit-by-one-digit multiplication
• Recognize multiplication patterns and build automaticity with facts

Common mistakes to watch for

The most common error is students multiplying only the tens place or only the ones place, forgetting to multiply both parts. For example, when solving 24 × 3, a child might compute only 20 × 3 = 60 and stop, or only 4 × 3 = 12 and stop, rather than combining them. Watch for answers that seem too small or for work that shows multiplication of just one digit. Another frequent mistake is reversing the digits in the answer, writing 84 instead of 48, which often signals the child hasn't visualized the tens and ones separately.
