Assessing Concepts of Geometry & Measurement in Adults

Instructor: Yuanxin (Amy) Yang Alcocer

Amy has a master's degree in secondary education and has taught math at a public charter high school.

Assessing adults in their mathematical comprehension is just as important as assessing this in younger students. Learn what techniques you can use to assess geometry and measurement in this lesson.

Assessing Adults in Math

Assessing how well adults understand mathematical concepts in geometry and measurement is important because it allows you, their teacher, to gauge whether they have successfully learned a concept or not. And, with the right assessments, the degree of understanding can also be found. It's actually crucial for you, as their teacher, to know just how much or how well your adult students understand these topics.

Regardless of the topic you are teaching, there is a set of different assessment techniques you can use. These include the following:

  • Formal testing is giving a test where each student does his or her own work without any input from the teacher or other peers.
  • Dialogue is the use of conversation to gauge a person's understanding of a matter.
  • Peer assessment is when fellow students check each other's work.
  • Feedback is when a teacher asks the student how he or she felt about the work. Feedback also includes asking the student what part of the problem was confusing.
  • Questioning is asking your student various questions so as to understand how and what your student is thinking as he or she is solving a problem.
  • Scaffolding is teaching in a way so as to connect with what your student already knows. It assesses what your students already know and helps you build on it.

You can use all of these techniques, or you can pick and choose the ones that suit your situation the best. Let's take a look at how you can do so.

Assessing Geometry and Measurement Skills

Let's talk about how you can use the above-mentioned techniques for assessing geometry and measurement skills. Assessing your students doesn't just happen at the end of a lesson; assessing your students happens throughout the lesson from the beginning all the way to the end.


Assessments are important in the beginning as they can tell you whether your students are ready for the lesson or not. For example, you can use questioning before you begin a lesson to see if your students have the required background knowledge to complete the lesson. If your lesson is about using a right triangle to help solve trigonometric problems, then you can ask your students whether they know/remember the trigonometric relationships that exist in a right triangle such as sine equals the opposite side over the hypotenuse. If your students don't, then you can take a moment to reteach those relationships.


As you are going through your lesson, use dialogue to converse with your students to make the lesson more memorable. Also, teach with scaffolding in mind so you can link the new information to things your students already know. For example, say you're teaching the properties of circles. You can relate the information about circles to real-world circles your students know such as wheels and pies.

You can use peer assessment after your students have completed some homework or a worksheet. With peer assessment, your students go over each other's work and explain to each other when there is something wrong. As the teacher, as you walk around and listen to your students, you'll know which students understand the material and which need more help.
