Units Of Measurement

Want hands-on Length Activities For Year 1? You’re in the right place! Our measuring length using informal units teaching resources will help your first grade/year 1 students learn to compare and order the length of several objects and make learning about length a breeze!

Before kids are introduced to measuring length using formal measuring tools like rulers and tapes, they need to be taught the essential skills and steps of the measurement process, known as non-standard measurement.

Teaching Length in Year 1

To build a deep understanding of the measurement process and the skills needed to measure accurately kids need to practice measuring using informal non-standard units like pop sticks, paper clips and blocks.

So what is non-standard measurement?

Non-standard measurement is using an informal unit to measure objects. It’s used by students in Foundation Stage, Kindergarten, Nursery, Reception and Year 1. The purpose of non-standard measurement is to focus the child on key measuring skills rather than reading tricky scaled instruments. Universal non-standard-measurement skills included learning to:

  • select the right tool to measure the object being measured
  • select the same unit and not different units when measuring an object
  • measure without gaps or overlaps
  • start and end the measuring in the right spots
  • measure it straight
  • be precise

The main difference between teaching measurement in Year 1 and the years below is the notion of using a uniform non-standard unit to find out how “much’ something measures. Previously students have not used units to say how big or small something is. Instead they have learnt to compare objects directly against each other to find out which is the biggest or smallest. 

When teaching Length to Year 1 Students your teaching programs should focus on:

  • using everyday language to compare 3 or more objects:

long, longer than

short, shorter than,

tall, taller than

  • Using direct comparison to compare objects. This involves placing two objects side by side, and lining them up, to see which is longer.
  • Using indirect comparison of two lengths – using a non-standard unit e.g. counters, cubes, paperclips, to decide which object is the longest or shortest
  • Learning to measure and compare the objects by lining up items from the same starting point
  • Understand that in order to compare objects the unit of measurement (non-standard unit) must be the same
  • Given a range of measuring materials which they can select freely to perform the measuring task. This encourages students to select the right tool for the job
  • Use a piece of string to indirectly compare & order the length of objects
  • Recognise that informal units must be uniform and used end to end without gaps or overlaps
  • Discuss why two groups of students might get different measurements for the same object
  • Estimating – encourage students to estimate their answer before completing the task, then review their guess, discussing how to make a good estimation
