Algebra tiles can be used by all students, and here you will learn how to create algebra tiles that are fully accessible for braille readers. The advantage of using algebra tiles over matches and boxes is that algebra tiles are not limited to representing only positive values of x.
You can find extensive information about algebra tiles online.
Let’s look at the example 2x = x + 6.
How to Prepare
- Cut out shapes from foam. Small squares represent the value one, rectangles represent x, and larger squares represent x^2. Add braille labels to the tiles using a braille labeler. In the example, we need three rectangles and six small squares.
- Use Wikki Stix© on the table to symbolize the equal sign.
With Students
Place the algebra tiles on each side of the Wikki Stix©.
Ask the students to solve the equation by removing one rectangle from both sides. The tiles will show us that the answer is x = 6.
Distinguish between positive and negative numbers and variables using braille, texture, and/or colour. The algebra tiles pictured below represent the equation -2x + 2 = x + 6.
