This week we started division. We reviewed the following division vocabulary and facts:

  • divide - To separate into equal groups. The opposite of multiply.


  • division box - Used to write a division question.

  • divisor - The number of equal groups or the number of items in each equal group.

  • dividend - The number being divided into equal groups

  • quotient - The number, not including the remainder that results from dividing.

  • remainder - The amount left over when a number cannot be divided equal.

  • A number divided by 1 equals that number.

  • 0 divided by any number equals 0.

  • No number can be divided by 0.

On Monday, we will continue with division by dividing 1-digit numbers into 2-digits and 3-digits.

Math 3 - Order of Operations

Use this strategy when determining the order of operations.

PEMDAS

1. Please-The “P” stands for Parentheses (brackets), Always do the operations in inner brackets First!!
2. Excuse- Exponents are next. Do all the square roots or powers.
3. My Dear- Multiply and or Divide from the left to the right.
4. Aunt Sally- Add and Subtract from the left to the right.


What we do is write out the problem in a notebook, then start from the beginning. “P” for parentheses.

For example:
5 x (9-4) +6 =
5 x 5 +6=

So far we have added the numbers in brackets, following order of operations, and our answer has been written underneath the sign of operation in brackets. Now we will Multiply my dear!
5 x 5 + 6=
25+ 6=

Finally Aunt Sally, we will add
25 + 6= 31

  2. Any number times 1 equals that number. (Example 15 x 1 = 15)
  3. Any number times 10 always ends in 0.
  4. Any number times 5 always ends in 5 or 0.
  5. Even numbers end in 0, 2, 4, 6, or 8.
  6. Odd numbers end in 1, 3, 5, 7, or 9.
  7. An even number times an even number always equals an even number.
  8. An odd number times an even number always equals an even number.
  9. An odd number times an odd number always equals an odd number.
