Bell Ringer – Math journal entry

In yesterday's lesson, we explored the Properties of Exponents and introduced the concept of radicals. A radical, characterized by its radicand and index, is essential for simplifying expressions. Students learned to find perfect squares and cubes for given radicands, apply mathematical operations, and understand the significance of positive and negative indexes. As part of the classwork, students collaborated to complete odd problems from the Simplifying Radicals worksheet. For homework, they are tasked with finalizing this worksheet to reinforce their understanding of radicals.

Presentation Transcript

  1. Bell Ringer – Math journal entry • Yesterday we discussed Properties of Exponents. • Summarize yesterday’s lesson using mathematical vocabulary. • Underline the math vocabulary words you use. • Choose 2 of your math vocabulary words and define them using either your smart phone, the textbook under your desk, or a dictionary from the bookshelf.

  2. RADICALS Thursday, August 29, 2013

  3. Vocabulary • What is a radical? What is a radicand? What is the index?

  4. Simplifying radicals • Look at the index. • If the index is 2, find the greatest perfect square that will go into the radicand. • If the index is 3, find the greatest perfect cube that will go into the radicand. • If the index is n, find the greatest perfect factor of n that will go into the radicand. • Pull out those perfect squares, cubes etc. Anything left over stays in the radicand.

  5. Simplifying radicals • When simplifying radicals with variables… • Divide the exponent of the variable by the index. • Pull out that variable. • Anything left over stays in the radicand.

  6. Reminders • Even indexes must be positive or they are imaginary, not real. • Odd indexes can be negative. • The square root of a number can be re-written as that number to the ½ power. Likewise, the cube root can be written as the number to the 1/3 power. So, the rules of exponents apply! • Radicals are like parenthesis. Distribute to everything. • Even root with an odd power…need absolute value!

  7. Classwork • With your learning partner, do the ODD problems from the Simplifying Radicals worksheet.

  8. homework • Complete the Simplifying Radicals worksheet.

  9. Exit ticket • On your index card: • First and Last name • Block • Seat Preference (number)
