1st Grade Math Practice: 20 Questions on Shapes & Measurement
A free practice set for 1st grade students on geometry and measurement — 8 easy, 8 medium, 4 hard. Naming 2D and 3D shapes, counting sides and corners, halves and quarters, comparing lengths, measuring with non-standard units, and telling time to the hour and half hour. Four options per question, with a parent-friendly explanation behind every answer. Built by the SOMATH team on the Upper West Side.
Who this is for. A 1st grader working on the Common Core geometry (1.G) and measurement (1.MD) standards — or a kindergartener who is reading well and ready for a stretch. The first 8 questions warm up with shape names, sides, and corners. The middle 8 step up to attributes, halves and quarters, and comparing lengths. The last 4 are real 1st-grade challenge work: measuring with non-standard units, telling time, and reasoning about shape composition.

How to use this practice set
Sit with your child. Read each question out loud, then read the four choices A, B, C, D. Let the child point to or say their answer before tapping Show answer. The explanation under each answer is written so a parent can read it aloud — we never just give the letter, we always show why.
All 20 questions stay inside Common Core 1st grade geometry and measurement standards. We cover naming and attributes of 2D and 3D shapes (1.G.A.1, 1.G.A.2), partitioning shapes into halves and quarters (1.G.A.3), ordering and comparing lengths (1.MD.A.1, 1.MD.A.2), and telling time to the hour and half hour (1.MD.B.3). Nothing here requires a ruler with inches or centimeters — that's a 2nd-grade skill.
8 easy questions — shape names, sides, corners
Question 1 of 20 · Easy
How many sides does a triangle have?
- 2
- 3
- 4
- 5
Answer: B — 3
A triangle always has 3 straight sides and 3 corners (vertices). The prefix tri- means "three" — like in tricycle (three wheels) or triplets (three babies). It doesn't matter how big or skinny the triangle is — if it has exactly 3 straight sides, it's a triangle.
Question 2 of 20 · Easy
Which shape has 4 equal sides and 4 square corners?
- Circle
- Triangle
- Square
- Rectangle
Answer: C — Square
A square has 4 sides that are all the same length and 4 corners that are all square (right angles). A rectangle (choice D) also has 4 square corners, but its sides are not all equal — usually two sides are longer. Every square is a special rectangle, but not every rectangle is a square.
Question 3 of 20 · Easy
How many corners does a rectangle have?
- 2
- 3
- 4
- 6
Answer: C — 4
A rectangle has 4 corners and 4 sides. Corners are the "points" where two sides meet. Squares also have 4 corners — in fact, every shape with 4 straight sides (a quadrilateral) has 4 corners. Look at a door, a book, or a picture frame — they're all rectangles with 4 corners.
Question 4 of 20 · Easy
Which shape is round and has no corners?
- Square
- Circle
- Triangle
- Rectangle
Answer: B — Circle
A circle has zero straight sides and zero corners — just one smooth, curved edge that goes all the way around. The other three shapes are all polygons, which means "many sides," and every polygon has straight sides and corners.
Question 5 of 20 · Easy
A hexagon has how many sides?
- 4
- 5
- 6
- 8
Answer: C — 6
A hexagon has 6 sides and 6 corners. The prefix hex- means "six." You see hexagons in beehives and on soccer balls. A pentagon has 5 sides (penta = 5), and an octagon (like a stop sign) has 8 sides (octo = 8).
Question 6 of 20 · Easy
Which solid (3D shape) looks like a ball?
- Cube
- Cone
- Sphere
- Cylinder
Answer: C — Sphere
A sphere is the 3D version of a circle — a perfect ball with no corners and no flat sides. A cube is like a box (think of dice). A cone has a point on top and a circle bottom (think of an ice cream cone). A cylinder is like a soup can — two circle ends and one curved side.
Question 7 of 20 · Easy
Which object is shaped like a cube?
- A pencil
- A die (one die from a dice game)
- A pizza
- A cereal bowl
Answer: B — A die
A cube has 6 square faces, all the same size. A regular game die is the classic example — that's why we call it a "cube." Sugar cubes and most building blocks are also cubes. A pencil is more like a long thin cylinder or hexagonal prism, a pizza is a flat circle, and a bowl is closer to a hollow sphere.
Question 8 of 20 · Easy
Which object is the longest?
- A crayon
- A pencil
- A school bus
- A paperclip
Answer: C — A school bus
Length is how far something stretches from one end to the other. A school bus is much longer than a crayon, pencil, or paperclip. In 1st grade, before we use rulers, we just compare objects by lining them up or by thinking about which one is obviously bigger or smaller (1.MD.A.1).
8 medium questions — attributes, halves and quarters, lengths
Question 9 of 20 · Medium
Which statement is TRUE about every rectangle?
- All four sides are the same length.
- It has 4 straight sides and 4 square corners.
- It has 3 sides.
- It is round.
Answer: B — 4 straight sides and 4 square corners
Every rectangle has 4 straight sides and 4 square (right-angle) corners. Choice A is only true for a square, which is a special kind of rectangle — not every rectangle. This is the kind of "defining attributes vs. non-defining attributes" question 1st graders work on in 1.G.A.1: the size, color, or orientation of a rectangle can change, but the 4 sides + 4 right angles cannot.
Question 10 of 20 · Medium
A square is cut straight down the middle into two equal pieces. Each piece is called:
- A quarter
- A whole
- A half
- A third
Answer: C — A half
When you split a shape into 2 equal pieces, each piece is one half of the whole (1.G.A.3). Two halves together make the whole back again. If you split a shape into 4 equal pieces, each piece is called a quarter or fourth — like a quarter of an apple or a quarter of a dollar.
Question 11 of 20 · Medium
A pizza is cut into 4 equal pieces. You eat 1 piece. What fraction of the pizza did you eat?
- One half
- One quarter (one fourth)
- One third
- The whole pizza
Answer: B — One quarter (one fourth)
When a whole is split into 4 equal pieces, each piece is one quarter (also called one fourth). Eating 1 of the 4 equal slices means you ate one quarter of the pizza. The other 3 quarters are still left.
Question 12 of 20 · Medium
Which of these is NOT a way to cut a square into two equal halves?
- A straight line from the top edge to the bottom edge through the middle
- A straight line from the left edge to the right edge through the middle
- A straight line from one corner to the opposite corner
- A wavy line drawn anywhere across the square
Answer: D — A wavy line drawn anywhere
To make halves, the two pieces must be the same size. Straight lines from edge to edge through the middle (A and B) make two equal rectangles. A straight line from corner to corner (C) makes two equal triangles. A wavy line drawn anywhere usually makes pieces that are not the same size, so it doesn't make halves. The key word in 1.G.A.3 is equal.
Question 13 of 20 · Medium
A pencil is 8 paperclips long. A crayon is 5 paperclips long. How many paperclips longer is the pencil than the crayon?
- 2
- 3
- 5
- 13
Answer: B — 3
"How many longer" means subtract: 8 − 5 = 3 paperclips. The trap is choice D (13) — that's the two lengths added together, not the difference. This problem is exactly the 1.MD.A.2 standard: measuring with non-standard units (paperclips) and comparing.
Question 14 of 20 · Medium
Three sticks: Stick A is shorter than Stick B. Stick B is shorter than Stick C. Which stick is the longest?
- Stick A
- Stick B
- Stick C
- You can't tell
Answer: C — Stick C
This is the classic transitive reasoning question in 1.MD.A.1. A < B and B < C, so A < B < C. Stick C is the longest, Stick A is the shortest, Stick B is in the middle. We never measured anything — we just compared sticks two at a time and put them in order.
Question 15 of 20 · Medium
How many flat faces does a cube have?
- 4
- 5
- 6
- 8
Answer: C — 6
A cube has 6 flat faces, and every face is a square. Pick up a die from a board game — you can see 3 faces at once (top, front, side), but it has 3 more on the bottom, back, and other side. Total: 6.
Question 16 of 20 · Medium
Which clock shows 3 o'clock?
- The hour hand points to 3, the minute hand points to 12.
- The hour hand points to 12, the minute hand points to 3.
- The hour hand points to 3, the minute hand points to 6.
- Both hands point to 3.
Answer: A — Hour hand on 3, minute hand on 12
At exactly an o'clock time, the minute hand always points to 12 (zero minutes past), and the hour hand points to the hour number. So 3 o'clock = short hour hand on 3, long minute hand on 12. Choice C (minute hand on 6) would be 3:30, the half hour. This is 1.MD.B.3.
4 hard questions — measuring, time, composing shapes
Question 17 of 20 · Hard
Sam lines up 3 erasers in a row to measure his book. Each eraser is the same size. The book is exactly the length of 3 erasers. Then Sam uses smaller paperclips instead, and the book is 12 paperclips long. About how many paperclips equal 1 eraser?
- 2
- 3
- 4
- 12
Answer: C — 4
If 3 erasers cover the same length as 12 paperclips, then we split the 12 paperclips into 3 equal eraser-groups: 12 ÷ 3 = 4. So 1 eraser = 4 paperclips. 1st graders don't formally divide yet (that's 3rd grade), so coach this as "make 3 equal groups from 12 — how many in each group?" using fingers or by counting up: 4, 8, 12. This is a real 1.MD.A.2 challenge problem about measuring the same object with two different non-standard units.
Question 18 of 20 · Hard
Two triangles are pushed together along their long sides to make one new shape. The new shape has 4 straight sides and 4 corners. Which shape did they make?
- A circle
- A pentagon
- A rectangle (or square)
- Another triangle
Answer: C — A rectangle (or square)
When two equal triangles join along a matching side, they form a quadrilateral — a 4-sided shape. If the triangles are right triangles (with a square corner), they form a rectangle or a square. This is 1.G.A.2: composing larger shapes from smaller ones. Many pattern-block sets show this on day one — two triangles snap into a rhombus or rectangle.
Question 19 of 20 · Hard
It is now 2:30. Where does the hour hand point?
- Exactly on the 2
- Halfway between the 2 and the 3
- Exactly on the 3
- Exactly on the 6
Answer: B — Halfway between the 2 and the 3
At the half hour, the minute hand is on the 6 (30 minutes past), but the hour hand has moved halfway from the 2 toward the 3 — because the hour is half over. This is the part of 1.MD.B.3 that trips up most 1st graders. Choice A (exactly on 2) is the common mistake; choice D (on the 6) confuses hour and minute hands.
Question 20 of 20 · Hard
A pizza is cut into 4 equal quarters. Maya eats 1 quarter. Her brother eats 1 quarter. What fraction of the pizza is left?
- One quarter
- One half
- Three quarters
- The whole pizza
Answer: B — One half
The pizza has 4 equal quarters. Maya ate 1, her brother ate 1, so 2 quarters are gone and 2 quarters are left. Two quarters of a pizza is the same as one half of the pizza — because two fourths equal one half. This is a real composing-fractions question (1.G.A.3) and a great place to bring out a paper plate and actually cut.
How to coach a 1st grader through these
Three habits from our Upper West Side classroom:
- Pull out the real object whenever you can. When the question is about a cube, hand your child a die or a building block. When it's about halves, fold a square napkin in half together. 1st graders learn shapes and measurement with their hands first, then with their eyes, then with words — in that order.
- Always count sides and corners out loud. When naming any 2D shape, point and count: "one, two, three, four sides … one, two, three, four corners." This single habit is what 1.G.A.1 is asking for: noticing the defining attributes instead of guessing by appearance.
- Use words like "equal," "half," and "quarter" every day. "Let's split this granola bar into two equal pieces — halves." "I'll cut the apple into four quarters." Children who hear these words at the kitchen table by 1st grade learn fractions much faster in 2nd and 3rd grade.
If your child gets stuck on a question:
- "Can you draw the shape?"
- "Can you count the sides and the corners?"
- "Can we find something in the room that's that shape?"
If those three don't unlock it, the issue is usually a vocabulary gap — a word like quarter, vertex, or equal the child hasn't owned yet. That's exactly what we diagnose in our free 30-minute evaluation.
