NYS Math Module 3

Module 3 combined a lot of old skills to further knowledge.  Students have worked on Area and Perimeter, double-digit by double-digit multiplication, and long division.  Each 4th grade teacher has tips and tricks for the students to remember the steps and formulas needed for these types of questions and math problems.

Area is the amount of space something takes up.  For example, the amount of carpet needed to cover the floor.  The formula for area is A=L x W (length times width).

Perimeter is the edge of a space or object.  For example, the fence needed to go around your backyard.  The formula for perimeter is P=S + S + S (side plus side).  You add up all the sides, no matter how many sides there are.

When multiplying double-digit by double-digit numbers (23 X 12), you need to remember to put a “magic zero” in before you start multiplying the number in the tens place.

Long division is similar to other division problems, however there are just more steps.  You need to remember to bring down all numbers.

Please see the examples below for reference.



NYS Math Module 2: Metric Conversions

This week our 4th grade students are working on metric conversions; moving from meters (m) to kilometers (km) and vice versa.  As well as, from meters (m) to centimeters (cm), liters (L) to milliliters (mL) and grams (g) to kilograms (kg).  When performing these conversions there are a few things that you must know:

  • 1,000 m = 1 km
  • 100 cm = 1 m
  • 1,000 g = 1 kg
  • 1,000 mL = 1 L

Here are a couple helpful websites:


Useful Websites

Hello!  I have added a new tab at the top of my page.  It is called “Useful Websites For Home”.  If you click on this tab, it will take you to a list of academic websites that your child can use at home.  Some sites will require logging in and that information will be sent home as soon as the username and password have been set.  The list will be updated as new sites are found.  Enjoy the resources! -Mrs. Dosch

Module 1, Topic A, Lesson 2

It is very important that students know what each number means.  For example, the number 639 means that there are 6 groups of one hundred, three groups of ten, and 9 ones.  In fourth grade, students need to know the place values up to the millions; ones, tens, hundred, thousands, ten-thousands, hundred-thousands, and millions.

The link below is a short YouTube video that shows a teacher that is teaching the main idea from the classroom math lesson.

Welcome to 4th Grade AIS

“You have brains in your head and feet in your shoes, you can steer in yourself in any direction you choose!” -Dr. Seuss

I am excited to introduce a new webpage for 4th grade AIS!  My goal is to to share what is taking place in our groups weekly.  This will include activity updates, extra practice information, a newsletter, and much more. I will also share any tips and tricks that could be helpful when completing grade-level work.
