1st Grade Math Problems: 40 Practice Questions With Answers
Practice 40 first grade math problems across 9 topics with step-by-step answers. Covers addition, subtraction, place value, shapes, telling time, and more. Reviewed by Cuemath’s expert tutors.
Finding the right math problems for 1st graders can be harder than it looks. Grade 1 covers a lot of ground: addition and subtraction within 20, two-digit place value, skip counting, measurement, shapes, telling time, and ordinal numbers. Most children need focused, topic-by-topic practice to build confidence before all of these skills are tested together.
This blog gives you 40 first grade math problems across 9 topics, all drawn directly from Cuemath’s Grade 1 curriculum and reviewed by Cuemath’s expert tutors. Each question comes with a step-by-step solution you can reveal with a click. Work through sections in order, or jump straight to the topic your child is practicing right now.
➕ 1. Addition Problems for 1st Graders
Objective: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
Addition in Grade 1 builds from counting all objects to counting on from the larger number, and finally to using known facts. By the end of first grade, students should recall all addition facts within 10 from memory and add numbers up to 20 using strategies like making ten or using doubles.
Where students make mistakes: Students often restart counting from 1 instead of using the count-on strategy. For 7 + 3, a student who counts from 1 says: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. A student using count-on starts from 7 and says: 8, 9, 10. Both reach the right answer, but count-on is faster and sets up mental math skills. Always start from the bigger number.
➖ 2. Subtraction Problems for 1st Graders
Objective: Demonstrate fluency for subtraction within 10; subtract within 20 using strategies.
Subtraction in Grade 1 covers three meanings: taking away, finding the difference, and comparing two quantities. Students move from using physical objects to drawing pictures to using number relationships. Key signal words that tell students to subtract include “left,” “fewer,” “more than,” and “difference.”
Where students make mistakes: Students often identify the wrong starting number in word problems. They may subtract the smaller number from the larger regardless of what the problem is actually asking. Teach students to first identify the starting quantity, then the amount being removed or compared.

🔢 3. Place Value Problems for 1st Graders
Objective: Understand that the two digits of a two-digit number represent amounts of tens and ones.
Place value is one of the most important concepts in Grade 1. Students learn that a number like 54 means 5 groups of ten (50) and 4 ones (4). This understanding extends to reading numbers up to 120, writing numbers in expanded form, and comparing two-digit numbers. Base-ten blocks are the main tool used to build this understanding.
Where students make mistakes: When reading a two-digit number like 34, students sometimes read it as “forty-three” because they see the 4 first and assume the larger single digit means a larger place value. Reinforce that the left digit always tells the tens. Use rods (each worth 10) and unit cubes (each worth 1) side by side with the written number until the connection is automatic.

🔄 4. Skip Counting Problems for 1st Graders
Objective: Count to 120, starting at any number less than 120.
Skip counting in Grade 1 builds the pattern recognition that underpins multiplication in Grade 3. Students count by 2s, 5s, and 10s, both forward and backward. Skip counting also strengthens understanding of even and odd numbers and helps students use the number line more efficiently.
Where students make mistakes: Students lose the pattern when skip counting backward. They often count backward by 1s instead of the correct interval. Keep a number line visible during backward practice. Have your child point to each number as they say it aloud before attempting it without the visual aid.
📊 5. Comparing and Ordering Numbers
Objective: Compare two two-digit numbers using the symbols >, <, and =.
Comparing numbers in Grade 1 means looking at the place value of each digit to determine which number is greater, lesser, or equal. Students compare the tens digit first. If the tens digits are the same, they compare the ones digits. Students also practice ordering a set of numbers from least to greatest.
Where students make mistakes: A common error when comparing 34 and 43 is comparing individual digits without thinking about place value: “The 4 in 34 is bigger than the 3 in 43, so 34 is bigger.” This is wrong. Teach students to always compare the tens digit first: 3 tens is less than 4 tens, so 34 < 43. Drawing base-ten blocks next to each number makes this error almost impossible.
📏 6. Measurement Problems for 1st Graders
Objective: Order three objects by length; measure lengths using non-standard units.
Measurement in Grade 1 focuses on two skills: ordering objects by length and measuring using repeated non-standard units like hand spans, paper clips, or cubes. Students learn that measurement must start at the edge of the object and that units cannot overlap or leave gaps. These skills build toward using rulers and standard units in Grade 2.
Where students make mistakes: Students often start measuring from somewhere in the middle of an object, not from its edge. They may also leave gaps between units or overlap them. When practicing with non-standard units, ask your child to lay units end-to-end carefully before counting, and always start from one end of the object.
🔷 7. Shapes Problems for 1st Graders
Objective: Distinguish between defining and non-defining attributes; build and draw shapes to possess defining attributes.
In Grade 1, students move beyond naming shapes to describing them by their defining attributes: the number of sides, the number of corners, and the type of lines (straight, curved, or both). They learn that the same shape can look different depending on its size or orientation, and that this does not change what kind of shape it is.
Where students make mistakes: Students identify shapes by appearance rather than by attributes. They may call a tilted square a “diamond,” or reject a very flat triangle as “not a real triangle.” Teach students to ask: How many sides? Are they straight or curved? How many corners? These attributes define the shape, not its size or orientation.
🕐 8. Telling Time Problems for 1st Graders
Objective: Tell and write time in hours and half-hours using both analog and digital clocks.
In Grade 1, students read analog and digital clocks to the hour and half hour. They learn that “half past” means 30 minutes after the hour. On an analog clock, the minute hand points to 12 for o’clock and to 6 for half past. At half past, the hour hand sits halfway between two numbers.
Where students make mistakes: The most common error is reading the minute hand as the hour hand. Students look at where the longer hand points and call it the hour. Teach the rule: the shorter hand tells the hour, the longer hand tells the minutes. At half-past times, the hour hand will be between two numbers, not pointing directly at one.
🏆 9. Ordinal Numbers Problems for 1st Graders
Objective: Use ordinal words and numbers to describe position; order objects first through twentieth.
Ordinal numbers describe position in a sequence: 1st, 2nd, 3rd, and so on. In Grade 1, students practice ordinal positions up to 20th. They also learn that position changes depending on which end you count from; 2nd from the front is a different position than 2nd from the back.
Where students make mistakes: Problems that ask about position from the back confuse many students. They count from the front by default, even when asked to count from the back. Encourage students to draw the line of objects and label positions from both ends before answering. A physical line-up with classmates is one of the best ways to build this intuition.
