An introductory 15-minute lesson for 6th-grade students exploring long division through the lens of accessibility and UEB Braille. Students learn the DMSB steps while understanding how math is represented tactually for blind learners.
"First, Divide: How many times does 2 go into 2? One time. We write '1' above the 2. In Braille, this '1' would be placed in the quotient's position."
"Next, Multiply: 1 multiplied by 2 is 2. We write '2' under the first 2 of the dividend. In Braille, this product would be positioned carefully below."
"Then, Subtract: 2 minus 2 is 0. We write '0' below. Again, in Braille, this subtraction result is recorded in its proper place."
"Finally, Bring Down: We bring down the next digit, which is 4. Now we have 4. We repeat the steps... Divide: 2 goes into 4 twice. Multiply: 2 times 2 is 4. Subtract: 4 minus 4 is 0. Our quotient is 12."
"Notice how, whether you're looking at it on the board or feeling it in Braille, the steps are the same, but the way we organize and represent the numbers is adapted for the medium."

[Display Slide 4: Practice Time!]
"Okay, your turn to think! Our new problem is 36 divided by 3. Think for a moment, how would you set this up? For those of you working visually, picture it on your paper. For our blind student, imagine using your abacus or Braille tools to lay out this problem. What would be the first step?"
[Lead discussion on similarities/differences. Facilitate sharing of ideas.]
[Display Slide 5: You Did It!]
"You all did a wonderful job today! Remember, math is a universal language, and tools like Braille ensure that everyone can speak it fluently. It's so important to understand and respect the different ways we all learn. Keep up the great work!"
