Grade Levels

Measurement, grade by grade

Taught from Kindergarten through Grade 8. Each grade band below lists the skills its lessons teach, with one real problem from that band solved step by step.

Kindergarten–Grade 2

Taught through Measurement (Grades K–2), Telling Time (Grades 1–2) and Money (Grade 2) — 26 lessons.

Worked example · Grade 1 Telling Time

123456789101112

What time is shown on the clock?

  1. The short hour hand points right at the 3, so the hour is 3.
  2. The long minute hand points straight up at 12, which means 0 minutes.
  3. Hour 3 and 0 minutes: the time is 3:00.

Answer: 3:00

Grades 3–5

Taught through Measurement (Grades 3–5), Area & Perimeter (Grade 3), Elapsed Time (Grade 3) and Volume (Grade 5) — 24 lessons.

Worked example · Grade 3 Elapsed Time

How many minutes from 1:35 to 3:05?

  1. From 1:35 up to 2:00 is 25 minutes.
  2. From 2:00 to 3:00 is 1 hour = 60 minutes.
  3. From 3:00 to 3:05 is 5 more minutes.
  4. Add the jumps: 25 + 60 + 5 = 90.
  5. So 90 minutes pass from 1:35 to 3:05 (1 hour 30 minutes).

Answer: 90

Grades 6–8

Taught through Volume (Grade 8) — 5 lessons.

Worked example · Grade 8 Volume

A sphere has a radius of 8 cm. What is its volume in cubic centimeters? Use π ≈ 3.14. Round to the nearest hundredth.

  1. Volume of a sphere = ⁴⁄₃ × π × r³, with π ≈ 3.14.
  2. r³ = 8 × 8 × 8 = 512.
  3. 3.14 × 512 = 1607.68, and 4 × 1607.68 = 6430.72.
  4. 6430.72 ÷ 3 = 2143.5733…, which rounds to 2143.57. The volume is 2143.57 cubic centimeters.

Answer: 2143.57

Frequently Asked Questions

What measurement skills should elementary students learn?

Students progress from comparing length, weight, and size (K-1st) to measuring in inches and centimeters (2nd), mass, liquid volume, and area and perimeter (3rd-4th), converting customary and metric units (4th-5th), and volume of solids (5th, with spheres, cylinders, and cones in 8th). Both customary (inches, feet) and metric systems are taught.

How do I teach measurement at home?

Measurement is perfect for hands-on learning. Cook together (measuring cups, teaspoons), measure furniture and rooms, weigh ingredients, track temperature, time activities, and compare distances. Using real tools like rulers, scales, and measuring cups builds practical skills and mathematical understanding simultaneously.

When do kids learn to tell time and count money?

Telling time begins in 1st grade (hour, half hour) and progresses through 2nd grade (5-minute intervals) to 3rd grade (1-minute intervals and elapsed time). Money is a 2nd-grade topic here: identifying coins, counting coins up to $1, and making change.
