Welcome to the website for the Whole Numbers Class. Here you can find things to help you get better at math including worksheets from class, interactive flash cards, and videos that explain how to do the problems.

Information about the Final Test

The final test is scheduled for Wednesday, July 13th, during our regular class time (12:45 - 2:00).

Here are videos that explain how to do some of the problems:

Lately we have been working on division.

Practice with a worksheet:
Like multiplication, word problems that require division usually involve rates

Wednesday 6/22

Over the last few classes, we have been working on multiplication.
Here are some things to remember:
  • We often say "times" when we multiply.
    5 x 2 is read as "5 times 2".
  • The result of multiplying is called the product
  • The order of the numbers being multiplied does not matter.
    5 x 2 is the same as 2 x 5

Practice with a worksheet:
There are some key words that tell us to multiply. For example:
  • "double" means to multiply by 2
  • "triple" means to multiply by 3

Word problems that involve multiplication usually use rates

Monday 6/13

Today we started looking at subtraction. Some important things to remember are:
  • The order of the numbers is important ("3 minus 1" is NOT the same as "1 minus 3")
     
  • For multi-digit subtraction, we start in the ones place and work our way left.
    For example, to do 347 - 182, we would start with 7 - 2
     
  • If the bottom digit is bigger than the top digit, we need to borrow/regroup
     
  • We can check our answer by adding
    For example, 34 - 15 = 19 ... Check the answer by adding ... 15 + 19 = 34

Be careful if you are borrowing from a zero, (also called "subtracting across zeros").

Here's a video that shows you how to borrow from zeros.


We also covered subtraction word problems. A subtraction word problem usually involves:
  • separating things
  • taking something away

Assignment due on Wednesday 6/15:
Remember to read carefully. Some of the word problems have extra information that you don't need.

Wednesday 6/8

We looked at addition today. Some important things to know include:
  • When adding multi-digit numbers, start in the ones place and work your way to the left
    (For example, when adding 26 + 37, we would start with 6 + 7)
     
  • If the result you get is a two-digit number, write down the number from the ones place and carry the number from the tens place. This is also called regrouping.
    (For example, to add 26 + 37, we would start with 6 + 7, which is 13... write down the 3 and carry the 1).

Addition word problems will usually involve:
  • putting things together
  • combining things
  • things that should be counted together
Watch out for extra information that you do not need, for example, information about oranges in a problem that asks about apples.

Monday 6/6

Today we work on place value as well as writing numbers as numerals and words.

We will start studying addition next week, but for now, it is very important that we can communicate the numbers to each other.

For everything else we do in this class, it will be very important for students to know their math facts.
