Teacher Introduction

A little about Sra. Dyroff: I am from the happiest country in the world; Colombia, South America! This is my eighth year teaching in North Carolina, but I have 23 years of experience as an Early Childhood Educator. I have taught all elementary levels from K through 4th, and have thoroughly enjoyed each one of them. I joined the Casa team in January of 2014 and love being part of this great family!

I have a Bachelor of Science in Early Childhood Education, a Master of Science in Multidisciplinary Studies and lower elementary Montessori certification from the North American Montessori Center. I hold a North Carolina Teaching License for Elementary Education K-6.

I am married and have 3 kids and 2 cats. Nicole is 25, Luna is 12, and Camilo is 9 and a Casa student since pre-K.  My family is my #1 priority. I love learning, reading, and binge watching on Netflix. I am looking forward to a great year with all of my new 3rd and 4th grade students and delighted to have some returning students. We have an exciting year planned and I can’t wait to get started! Bienvenidos!

A little about Sra. Bohorquez: Hello parents! My name is Liliana Bohorquez. I am originally from Cali, Colombia. I have a Bachelor’s degree in Animal Science. This will be my 3rd year working with Sra. Dyroff. I am very happy to have the opportunity to assist her and your children.

I have lived in the United States for the last sixteen years. During this time, I have worked as a Quality Control Supervisor in poultry and fish processing plants. Before coming to Casa, I worked as a Teacher’s Assistant in a Montessori school located in Greenville, NC where I implemented a small Spanish curriculum for young children. I really enjoy mentoring children and helping them to meet their needs.

I have a nine-year-old daughter who is a student at Casa. I love animals, and recently adopted a dog.

I am looking forward to meeting you and your children!

Everyday Math-http://everydaymath.uchicago.edu/






3rd Grade: Earth Systems, Structures and Processes

  • Compare the structures of the Earth’s surface using models or three-dimensional diagrams.

4th Grade:

  • Energy: Recognize that energy takes various forms that may be grouped based on their interaction with matter.
  • Nutrition: Understand food and the benefits of vitamins, minerals and exercise.


3rd Grade: Fractions

Focuses of the Unit:

During this unit, students will:

  • Explore the meaning of fractions and develop an understanding that fractions are numbers.
  • Represent fractions using drawings, number lines, and symbols (such as ¼)
  • Use their knowledge of fractions to solve word problems.
  • Compare two fractions by reasoning about their size.

Ideas for home support:

Fractions in our world:  Look for fractions in your everyday life to help your child make sense of fractions.  Talk to your student about where you see and use fractions in your life (at home, at the grocery store, on your job, etc.).  Look around the house and locate items that have or use fractional amounts.  Challenge your student to find fractions in their world.  Discuss opportunities such as:

  • If we want to share a pan of brownies with the four people in our family, how can we share them equally? How much does each person get?  What if you have a friend over?  How does that change each person’s share?
  • The tea pitcher holds 2 gallons, but right now it is one-half full. How much tea do we need to make to fill up our pitcher for dinner?
  • If we cut a whole pizza into 8 equal slices and our family ate 4 slices, what fraction of the pizza did we eat? How can we describe that fraction two ways? (1/2 or 4/8)

Parts of a Whole:  At school, third graders will be exploring ways to combine fractions to make a whole.  (For example ½ + ½ = 1).  Cooking provides a great experience for practicing and putting these ideas to use.  If a recipe calls for 1 cup of sugar, give your student the ½ cup measuring cup and ask how we can measure that amount with that measuring cup.  What other cups could you use to make that same amount (1/4 cup, 1/8 cup, 1/3 cup, etc.).  Then have them check their guesses by pouring those into a one-cup measuring cup to see if it fills the cup.

4th Grade: Fractions

During this unit, students will:

  • Use models to understand equivalent fractions.
  • Use different strategies to compare fractions with different numerators and denominators while understanding the size of the whole matters.
  • Decompose fractions into smaller fractions using equations and models.
  • Add and subtract fractions and mixed numbers with like denominators.
  • Solve word problems involving addition and subtraction of fractions.
  • Use models to multiply a whole number by a fraction and solve word problems using these models.
  • Understand how decimals and fractions are related (1/10=0.1) and make comparisons using this understanding.

Social Studies

3rd- Culture

  • Understand how diverse cultures are visible in local and regional communities.
