Measurement in a Junior class

MEASUREMENT

In a junior math class, non-standard units of measurement are often used to introduce students to the concept of measurement before moving on to standardised units.

Non-standard units of measurement are arbitrary units that are not based on any established system of measurement. Examples of non-standard units of measurement include using paperclips to measure length or using marbles to measure weight.

Using non-standard units of measurement can help students develop an understanding of the basic principles of measurement, including the concepts of units, precision, and accuracy. By using non-standard units, students can also practice estimating measurements and comparing the relative sizes of different objects.

Once students have developed a basic understanding of measurement using non-standard units, they can then move on to using standardised units of measurement such as inches, feet, grams, and kilograms. Standardised units are important because they allow for accurate and consistent communication of measurements across different contexts, and they are widely recognised and understood within various professions and industries.

In measuring hands and feet using non-standard units, you can use common objects as your units of measurement. For example, you can use paperclips, pencils, or even your own fingers to measure the length of a hand or a foot.

Our Mission in Team Koru

Understand the concept of measurement and units of measurement.
Students will practice measuring the length of hands and feet using non-standard units.
Students will compare and contrast measurements using different non-standard units.

Materials:

Scissors

Paper

Pencils
Template
Different counting materials to use as non standard measuring units

Procedure:

Introduction:

Begin by asking students if they have ever measured anything before, and what units of measurement they are familiar with.

Explain that today, we will be learning about non-standard units of measurement.
Show students some examples of non-standard units, such as paperclips and pencils.

Measuring Hands: Have students trace around their own hand and foot.

Demonstrate how to measure the length of a hand using 4 different objects to measure the length of their hand and foot and explain that they should count the number of paperclips that fit between the tip of the middle finger and the tip of the thumb.

Have the students record their measurements on the template given, and then share their results with the class.

As a class, compare and contrast the measurements 

Wrap-Up 

Review the concepts of non-standard units and measurement, and ask students to share what they learned today.
Have students reflect on what they learned and what they found challenging about measuring with non-standard units.
Collect the reflections and discuss any common themes or misconceptions.
