What Your Child Will Learn
- Skip count by tens starting from any given number to solve multiplication problems involving groups of 10
- Recognize that multiplying by 10 creates a pattern where the number of tens equals the product (e.g., 3 × 10 = 30)
- Apply skip counting strategies to solve word problems that involve equal groups of 10 items
- Demonstrate fluency in identifying multiples of 10 up to 100 through repeated addition and multiplication
How to Use This Worksheet
- Step 1: Begin by reviewing skip counting by tens aloud as a class. Use a number line or hundreds chart and have students echo each number (10, 20, 30, 40, etc.). This activates prior knowledge and reinforces the rhythm and pattern of tens.
- Step 2: Introduce each multiplication problem one at a time. For the first 2-3 problems, model using ten-frames or base-ten blocks to physically create the groups. For example, if the problem is 2 × 10, build two groups of 10 blocks together and count the total.
- Step 3: Have the student transition to drawing or circling groups. For problems 3-6, ask them to draw circles or boxes representing groups of 10, then count by tens to find the answer. This bridges concrete manipulatives to pictorial representation.
- Step 4: For problems 7-10, encourage independent skip counting without drawing. Student should point to each ten on a number line or hundreds chart while saying the multiples of 10 aloud, then write the final number as their answer.
- Step 5: After completing all 10 problems, review the answers and look for the pattern together. Ask: 'Do you notice all our answers end in zero? Why do you think that is?' This metacognitive reflection solidifies understanding of the × 10 pattern.
Tips for Parents & Teachers
Many Grade 1 students struggle with the abstract concept that 10 × 4 means 'four groups of ten.' Use concrete manipulatives like ten-frames, bundled sticks in groups of 10, or base-ten blocks to make the grouping visible before moving to symbolic representation. Have them physically count out four bundles of 10 objects to reinforce the connection.
A common mistake is having students skip count incorrectly (saying '10, 20, 30, 40, 60' instead of '10, 20, 30, 40, 50'). Practice skip counting by tens daily using a number line or hundreds chart, and have them touch each number as they count to maintain accuracy and build automaticity.
For hard difficulty, challenge students to solve problems where they must determine HOW MANY tens are in a given number (e.g., 'How many tens are in 50?'). This reverses the thinking and deepens their understanding of the multiplicative relationship between groups and totals.
Use consistent language when presenting problems: 'three groups of ten' and '3 × 10' should be used interchangeably so students understand these represent the same mathematical idea. Avoid switching randomly between different ways of expressing the same multiplication fact.
Frequently Asked Questions
Why is 'counting by tens' considered multiplication if my child is just skip counting?
Skip counting by tens IS multiplication in its most concrete form for Grade 1 students. When your child counts '10, 20, 30, 40' to solve '4 × 10,' they are demonstrating multiplication—they are finding the total of four groups of ten. This skip counting strategy is the foundation for understanding that multiplication means equal groups, and it's developmentally appropriate for Grade 1. As students progress, they'll move from counting strategies to memorized facts, but the counting method builds genuine understanding of what multiplication means.
My Grade 1 student can skip count by tens but still guesses randomly on the multiplication problems. What should I do?
This is very common at the hard difficulty level. Your student may not yet see the connection between skip counting and multiplication symbols (×). Use language that explicitly links the two: 'We're going to count by tens THREE times because we have 3 groups of 10.' Point to the '3' in '3 × 10' and say 'this number tells us how many times to skip count.' Consider using a recording chart where they write down each number they say while skip counting, then circle or highlight the final number as the answer. This visual record helps solidify the counting-to-answer connection.
Should my child memorize the × 10 facts, or is skip counting enough?
For Grade 1 at hard difficulty, skip counting is the appropriate strategy and should not be rushed into memorization. However, through repeated practice with these 10 problems, your child will naturally begin to notice and remember patterns (all answers end in zero, each answer is 10 more than the last). This natural pattern recognition is the beginning of fact fluency. Your role is to celebrate when they notice the pattern themselves rather than drilling facts. By the end of Grade 1 or early Grade 2, this repeated experience will have built both understanding and automaticity.
