InCA Assignment for 1/15

We will have a pairs quiz in class Thursday, January 16 (i.e., tomorrow). It will include content on everything we have done so far. You will be assigned pairs at the start of class and be given the whole period to work. Fair warning: You will NOT be permitted a graphing calculator during this test.

Today, you should review. There are several links below to work on, but in class you’ll be given instructions to complete at least one IXL module to a score of 80+.

New instructions to log in to IXL

  • Go to http://www.clever.com and click “Log in as a student”
  • Search for Ithaca High School (if necessary) and select “Log in With Google”
  • The system will connect to your ICSD Google account and you’ll be taken to a “homeroom” page. From there, you can click the IXL icon to log in.

Once you are logged in, complete one of the following to a score of 80+

There are others linked below, but you are expected to complete one of these three.

InCA Assignment for 1/14

There will be a quiz on Thursday, January 16 on what we’ve done so far in Unit 4, including evaluating/simplifying expressions with radicals and rational powers.

Period 3

We spent some more time with “nth” roots (the general term for any radical: square root, cube root, fourth root, etc. We observed that evaluating an expression with a radical is similar to but subtly different from solving an equation with a power. See the notes for more details.

Period 8

We played a review relay race game to quickly recap the work we’ve done so far in this class. Tomorrow, you’ll have some time to work on the review sheet posted below as well as to do some IXL work.

InCA Assignment for 1/13, plus Quiz Warning

My two periods are still not quite in sync with each other, so check for your period below. Both periods will have a quiz on the unit so far on Thursday, January 16

3rd Period

We finished the lesson started Friday about simplifying radical expressions

InCA Assignment for 1/10

All InCA students will have a Homework Quiz on Monday of the following assignments (these assignments came out in different orders for different periods, but the numbering is the same):

  • HW 4.2 – Evaluating Rational Powers
  • HW 4.3 – Multiplying/Dividing Radicals
  • HW 4.4 – Simplifying Radical Expressions with Rational Roots

Review the homework keys and videos for the past few days to prepare!

3rd and 8th periods did different things today (you’ll be aligned again come Monday)

3rd Period

We returned to our work with fractional exponents and used them to simplify radical expressions

8th Period

Rational exponents are equivalent to radicals, therefore the shortcuts that we can use working with exponents extend to radicals as well. Today we discussed multiplying and dividing radical expressions.

InCA Assignment for 1/9

3rd and 8th periods did different things today:

3rd period students

We spent some time noticing some things about the powers reference list you’ve created. Many powers evaluate to the same thing (2^6, 4^3, and 8^2 for example, as do 3^4 and 9^2) and you were challenged to come up with why. After that, we played a competitive game where you tried to find as many different ways of expressing the number 256 using multiplication and exponents.

Your homework tonight is to repeat the game with the number 32. A reminder of the rules:

  • The only operations allowed are exponents and multiplication
  • Each term of your expression must have an exponent
  • You may have at most one exponent = 1

Rational exponents are equivalent to radicals, therefore the shortcuts that we can use working with exponents extend to radicals as well. Today we discussed multiplying and dividing radical expressions.

A reminder: because I want you to be able to work through this chapter without relying on the calculator, we will have a daily Powers Quiz. I will choose 10 powers from the reference table you made and ask you to evaluate them without using the calculator in a brief, timed quiz. We will do this every day through the unit, and only  your highest grade on any one quiz will be the one used in your Unit 4 grade.
