Description

Overview:
This lesson helps to build procedural skill with identifying unit fractions on a number line (and ruler). The partitioning of number lines and rulers is used here to introduce the idea that fractional lengths are invariant. This work develops students' understanding that a length does not change if its position on a number line or ruler changes.

The guide is a basic way of introducing fractions in relation to measure but the connect isn't fully clear. An instructor will need to supplement different pieces as needed to make sure students conceptually understand what is going on.

There are some procedural assessments in this guide but very little conceptual elements. These conceptual elements are extremely helpful to make sure learners are understanding the maths

There wasn't much depth to the curriculum guide It does offer a few examples and some practice but there wasn't much depth with the fractional understanding. By supplementing this lesson, an instructor could develop a better conceptual lesson.

The materials offered in this guide serve to begin the conversation stated in the lesson objective and description; however, more explanation is needed in places. For example, there is mention of counting some lines as odd without giving sufficient explanation for why this is done and when it is to be applied. Likewise, an opportunity is missed in the guide to discuss why some rulers use 1/8, 1/16, 1/32, 1/64 and to attach those discussions to real-world matter and deeper understanding.

The measuring activities are appropriate for practice; however, the quality of the images is poor in places and makes it difficult to know what fraction is offered in the answer choices. Also, the second Khan Academy video focuses on the metric system and doesn't connect at all to the examples above and below the video which uses inches.

Quality of Instructional and Practice Exercises: Limited (1)

This guide offers a few examples and some practice; however, there are no answer keys and no variation in exercise type or format beyond videos and written problems with visuals. This resource could be made stronger by adding some real-world examples for students to explore from the beginning to better comprehend why there are different graduations on rulers, what patterns can be seen between them, and how to use the tools to measure actual objects around the classroom, etc.

This guide serves to give a brief overview of reading 8ths and 16ths; however, it could be made stronger if it connected deeper meaning between those two values. Use of real-world practice and examples would give students more opportunities for deeper learning and engagement.
