What's included

36 live meetings
27 in-class hours
Homework
1-2 hours per week. Students will be expected to complete 4-8 pages of homework each week. Assignments will be posted in the Classroom on MONDAYS. We do not go over every question in the homework, but 15 minutes per class is set aside to discuss tricky problems.
Assessment
Students are assessed constantly during their work in class. Throughout the activities, we discuss our thinking and our strategies for approaching problems. Upon request, I will provide a written evaluation for your student.

Class Experience

US Grade 2 - 4
Beginner - Intermediate Level
I believe success in math depends on a child's ability to not only understand numerical concepts, but to be able to apply those strategies to problems by using mathematical thinking.  My approach in this class is to give students the tools they need to be able to solve problems, and then allow them to experiment, fail, and try again until they get the answer.  Throughout the year, we work on developing strategies, understanding relationships, and building confidence.  As I tell my students, there is always one right answer in math, but there is not just one way to get there.  

This class uses Dimensions Math, a Singapore Math curriculum.  Singapore Math is a mastery-based approach to math, where students progress from concrete examples (real life), to pictures, and finally apply their knowledge to the abstract, using numbers and algorithms.  Students do a lot of hands-on work, as well as, mental math.  Instead of mimicking procedures, they learn how to think mathematically and apply what they know to solve problems.  

I specialize in personalized learning, and I try to meet the needs of each and every student in my class.  This class size is small--I max at 5 students--so each child has a chance to participate often, gain confidence, and so that I can give every student the attention they need.  Because the class is structured this way, it is very important that students are at the right math level. It's perfectly okay if you enroll your child in the wrong level at first.  (Sometimes it's easier to tell where a child fits in, just by having them play games in a few classes!) However, be aware that I may suggest moving them up or down a level once I get to know them.  

If you'd like more help placing your child, please see the prerequisites below, or reach out to me with any questions.   

********************
CLASS FORMAT 
********************
This class is for students working in Level 3A (roughly 3rd grade) in the Dimensions (or other Singapore) curriculum.  Class time consists of instruction of the material, as well as time to practice through games and other activities.  The general format is as follows, though I do change things based on the topic we are covering and the needs of the students.  Often games have many "teachable moments" where instruction is integrated.   

5-10 minutes:  Instruction in math or in the game we are playing
20-25 minutes:  Game play or activity
15 minutes:  Review of the workbook pages

Students are expected to be working on math outside of class.  At the beginning of each week I post workbook pages from the Dimensions 3A workbook.  These pages are highly recommended, as they offer additional practice and are scaffolded to help students develop better mathematical thinking.  We DO NOT go over every problem in the workbook pages, however, I do reserve about 10 minutes at the end of each class to review the pages or answer specific questions students may have.  

***********************
2024 SCHEDULE 
***********************
This class begins the week of July 29, 2024 and ends the week of January 6, 2025.  Level 3B follows this class and will begin in January 13, 2025.

*********************
PREREQUISITES
*********************
Singapore Math is structured a little bit differently than other math programs.  In order to succeed in this level 3 class, your child should know the following skills: 

-Adding and subtracting 3-digit numbers easily
-Place value understandings:  hundreds, tens, ones
-Has been introduced to multiplication & division and knows some facts

If you're not sure about what level is best for your child, you can get a placement test here: https://www.singaporemath.com/placement-tests/

Learning Goals

By the end of the semester, students will know the following: 
-Adding & Subtracting 4-digit numbers
-Place Value to 10,000
-Multiplication and Division of 2- and 3-digit numbers
