What Your Child Will Learn
- Solve multiplication problems where one factor is 10 using skip-counting by tens as a strategy
- Recognize patterns in products when multiplying any number by 10 (e.g., 3 × 10 = 30, 4 × 10 = 40)
- Apply the commutative property of multiplication to understand that 10 × 5 equals 5 × 10
- Translate real-world scenarios (groups of 10 objects) into multiplication expressions and solve accurately
How to Use This Worksheet
- Step 1: Before starting, review skip-counting by 10s together. Have your student count aloud by tens to at least 100, pointing to fingers or a hundreds chart to reinforce the sequence.
- Step 2: Work through the first 2-3 problems together as a model. For each problem (e.g., 5 × 10), ask your student to identify how many groups of 10 they have and skip-count aloud that many times.
- Step 3: Have your student complete problems 3-7 with light support. Encourage them to use physical objects (bundled straws, base-ten rods, or drawn circles representing 10s) if needed to visualize each multiplication.
- Step 4: For problems 8-10, allow independent work. Remind your student that if they get stuck, they can skip-count by 10s on their fingers or use a number line marked in tens.
- Step 5: Review all answers together. For any incorrect responses, replay the problem using objects or drawings to show why the answer should be the product of the other factor and 10.
Tips for Parents & Teachers
Many Grade 1 students struggle to see the pattern when multiplying by 10—explicitly show that the single number just gets a '0' added (e.g., 6 becomes 60 when multiplied by 10). Use tens frames or bundles of 10 base-ten blocks to visualize this concrete connection before moving to abstract notation.
Watch for students confusing multiplication with addition. If a child writes 3 × 10 = 13 (adding instead of multiplying), redirect by asking, 'How many groups of 10 do we have?' and physically group items into 3 sets of 10 to reinforce the meaning of multiplication.
Use skip-counting as the primary strategy at this level. Have students verbally skip-count by 10s (10, 20, 30, 40...) while pointing to each problem, which builds fluency and helps them internalize the pattern without memorization.
Frequently Asked Questions
Why is multiplying by 10 considered 'hard' for Grade 1 when it seems like just adding a zero?
For Grade 1 students, the conceptual understanding of multiplication itself is still developing. Many students at this level are just beginning to understand that 3 × 10 means '3 groups of 10,' not just the rule 'add a zero.' The challenge is connecting the abstract notation to concrete quantities and skip-counting strategies, not just memorizing a trick. Focusing on the meaning helps students build flexible multiplication thinking.
My student can skip-count by 10s but still gets confused when writing the answer. What should I do?
This is very common at Grade 1 level. Have your student skip-count aloud while writing the numbers: '10, 20, 30...' and write down each number they say. This bridges the auditory/verbal skip-counting with the written answer. Gradually they'll notice the pattern and connect their voice to the written form.
Should I teach the '×10 = add a zero' rule, or stick with skip-counting?
At Grade 1, prioritize skip-counting and visual/concrete understanding first. The 'add a zero' rule is a shortcut that works but can confuse students later (e.g., when multiplying 10 × 0.5). Building strong conceptual understanding now—knowing that 7 × 10 means 7 groups of 10—gives them a foundation for deeper multiplication learning in higher grades.
How can I help my student see that 10 × 5 and 5 × 10 are the same?
Use physical objects arranged in two different ways: show 10 groups of 5 objects, then reorganize them into 5 groups of 10 objects. Have your student count the total both ways to see that the answer is identical (50). This concrete demonstration of the commutative property is more meaningful than just stating the rule.
