There are a variety of ways that students learn and process information. Differentiating the approach to teaching to create a safe space for all students to learn by providing multiple means of representation is a great skill to have as an educator. Providing options ensures that all students have an equitable chance in expanding their knowledge. There are many ways that this can be done.
One way to do this is to introduce content in multiple forms. This could be doing a lecture, watching a video with closed captions, text to speech for any required readings, or any other fun way to present content. Another key in introducing content is to incorporate a variety of cultural perspectives. In math, you can discuss the different ways that cultures solve specific problems. For example, when teaching geometry, you can discuss varying architecture approaches or geometric art.
When it comes to math, there are many vocabulary words and symbols that students must know to be able to understand the math. Having a place to post vocabulary words and their definitions and math symbols and what they mean will create an equitable opportunity for all students to utilize this tool. This is also a great opportunity to address biases in math language and symbols. I would have a poster of all the relevant math vocabulary and symbols used and also have a handout to provide to each individual student.
Another way to provide multiple means of representation is to expand the knowledge of your students. This can be done by expanding or referring back to previous understandings or experiences. You want to build on what students already know. If you ask students to answer a word problem about a topic that they do not know about, this will only confuse students more. Students will also question "why do I need to learn this?" Explaining to students the importance of why we are learning what we are will help with their engagement as well. If students understand the purpose, it takes away that question that will distract or confuse them.
