Purchasing this product will provide you with a complete lesson to teach your students to rationalize the denominator.
It includes a powerpoint presentation of 11 slides. These slides introduce the problem, give students a guided opportunity to brainstorm, and three worked examples. These slides cover simple denominators with one radical, and more complex cases where the students need to multiply by the conjugate.
You will also worksheets. Two worksheets of the same difficulty level (and solutions!) are included. I love using different versions of the same worksheet in my practice. Students can work in pairs with each student having a different worksheet. Suddenly they're asking each other questions like "can you explain what you do on step 2" instead of "what number did you write next." Or, you can use one as a worksheet for homework and the second as a quiz.
