✐ This product is a NO PREP - SELF CHECKING activity that engage students in evaluating a "Finite Geometric Series". There are 2 options (with same set of questions) available in this EMOJI.

The two options are:

☑ Option 1: students have to use the geometric sequence explicit formula to find "n - number of terms"

☑ Option 2: "n - number of terms" is always given

There are 5 different models illustrated in this activity and students have to utilize the information given to find the Arithmetic Series.

In this activity students will be given:

☑ A List of terms of an Geometric Sequence (2 Questions)

☑ The first term, the common difference, and number of terms (3 Questions)

☑ The first term, the last term (or "n" in the second option), and number of terms (2 Questions)

☑ The first few terms of the Geometric Sequence and number of terms (3 Questions)

☑ The first few terms of the Geometric Sequence and the last term (2 Questions)

Students will work with sequences that are:

☑ Integers

Students should feel comfortable with:

☑ Using the Explicit Formula of an Arithmetic Sequence: an = a1 * (r)^(n-1) to find number of terms (in OPTION 1)

☑ Using the formula for evaluating Finite Geometric Series: Sn = (a₁ *(1 − r^n))/(1 − r)

☑ Using the exponents property: if a^n = a^m, then n = m

Students would need to solve the mystery Emoji by following the color key.

My students are fascinated with an additional coloring option that I have included where they could pick their own colors. They have become very very creative. I am including this option in this emoji and I truly hope that your kids will love it as much as mine have.

Please, take a look at the PREVIEW before purchasing to make sure that this creative activity meets your expectations. After seeing the preview, If you would like to modify it in any way, please don't hesitate to contact me via Q and A. I will update and include a second version in this product JUST FOR YOU ☻

✶ ✶ ✶ My students truly were ENGAGED AND LOVED THIS ACTIVITY. They had a BLAST COLORING and finding the mystery picture much better than the textbook problems.✶ ✶ ✶

This RELAXING EMOJI could be used in: math centers, group work, a way to check for understanding, a review, recap of the lesson, pair-share, cooperative learning, exit ticket, entrance ticket, homework, individual practice, when you have time left at the end of a period, beginning of the period (as a warm up or bell work), before a quiz on the topic, substitute planning, and more.

A suggested Step-by-Step Answer Key is included.

☺Would love to hear your feedback☺. Please don't forget to come back and rate this product when you have a chance. You will also earn TPT credits. Enjoy and I ☺Thank You☺ for visiting my ☺Never Give Up On Math☺ store!!!

Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the formula to solve problems. For example, calculate mortgage payments.
