♥ What is the MAGIC NUMBER? ♥

This product is to be used when finding the "Least Common Denominator (LCD) of Rational Expressions". Students will be given the denominators of rational expressions and asked to find their LCD. The denominators given maybe:

☒ Trinomials
☒ Binomials
☒ Monomials

There are 16 different rational expressions provided. These questions assess the following:

☑ Students are able to factor completely correctly
☑ Students are able to determine the LCD correctly

When completing the 16 questions, students will check for their answers on the Grid Form. Students are asked to match the number of the question with the letter of the answer. If a student chooses the correct answers, the sum of the numbers in the grid will be the same horizontally, vertically, and diagonally. The four corner boxes and the four center boxes will total the same amount, as well. If the students find that particular "same" sum, then they have the MAGIC NUMBER.

If the sums are not the same, then the student would need to check his/her work.

I always post the MAGIC NUMBER in the front of the class as a QR Code and students would come and check their findings against the QR Code. (See image above)

There are 2 options to use this product.
→ → Option 1: Individual Practice
→ → Option 2: Groups or Stations

In Option 1: Individual Practice students could work on this activity alone in the classroom, at home, or with a sub.

In Option 2: Groups/Sessions students will be divided into groups of 4 where each member of the group will be assigned a duty as described in the activity. Each student will select 4 questions to work with from the 16 provided. When completed students will map their answers to the grid and check to see their Magic Number.

Number of members of groups maybe adjusted based on attendance and so on. This activity could be used in groups of 2 or as Pair-Share. In this case, each student will get 8 questions to work with instead of 4.

This is a great way to review before a quiz or a test. This activity could even be assigned as a homework, recap of the lesson, review, individual practice, cooperative learning, or even while you're out. It is self monitoring. It is a good practice over this particular concept.

Research has shown that using self-assessment with students can positively effect self-efficacy and intrinsic motivation levels in students (Rolheiser and Ross).

This activity includes a suggested STEP-BY-STEP ANSWER KEY.
