Class Experience

In this class students will learn how to determine if two or more triangles are similar using the ratio, unit rate, or slope of the triangles. They will compare two different proportional relationships represented in different ways. This class will explain the difference between similar and congruent, use coordinate points and graphs.
I teach with slide presentations, where I show and explain examples, work through problems with the students, and then I provide practice problems for them to work on their own, including worksheets, if requested.
I strongly encourage interaction between students and myself because communication and understanding of the vocabulary is so important.

Learning Goals

Students will be able to use the ratio, unit rate, or slope to determine if a set of triangles are similar to each other.

Utah Teaching Certificate in Elementary Education

I'm Mrs. Essmeier, and I love teaching Mathematics. There are so many wonderful patterns to discover with numbers. Understanding why you use certain equations and how these concepts work is an important part of mathematics. My objective is to help my students to understand the connection between the math they learn and the real world in which they live. Mathematics is something you will use every day in one way or another. The more you know and understand, the more you will use. 

I provide one on one tutoring for one, two, or three days for one week or ongoing. My tutoring includes the topics found in the curricula for most 6th through 10th grades - number sense, equations, functions, graphing, geometry, fractions, decimals, and more.
I teach Monday - Friday. Please contact me to request times (include time zone) and days available.

I retired from teaching school after 39 years, but I'm not tired of teaching. I've been on Outschool since the fall of 2020. My various degrees include a Bachelor of Arts degree in Elementary Education, a Masters degree in Mathematics Education, a Math Specialist enhanced level 2, and an ESL endorsement. My teaching experiences include grades 2nd, 3rd, 4th, 5th, and 6th for 30 years. I then moved to the middle school and taught 7th and 8th grade for nine years.
I do hope to help many more learners understand and appreciation the beauty and need for mathematics.
