Math 2 - Week 8 Completion

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

• division - Sharing or grouping a number into equal parts. A quick way of subtracting.



• 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 (Jackson) - Lesson 8: Introduction to Decimals

We completed Lesson 8 through p. 109 in your textbook.

Vocabulary words:

1. decimal - A number with one or more digits to the right of the decimal point. Examples: 0.5 (five tenths); 0.25 (twenty-five hundredths)


2. decimal point - A symbol used to separate dollars from cents in money and to separate the ones place from the tenths place in decimals.

HOMEWORK:

Read p. 112 (Adding and Substracting Decimals) and complete sections A and B on p. 113.

Math 3 (Jackson) - Starting Decimals on Monday, June 2

We reviewed the answers to the GED Mini-Test (Lessons 5-7) on pages 100-103 in your textbook.





Complete the GED Practice - Fractions given out in class. We will review the answers on Monday, June 2.


Monday, June 2 - Agenda

• Review GED Practice - Fractions word problems


• Start Introduction to Decimals, p. 104

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

Math 2 - Math Facts and Patterns

A good mathematician looks for patterns. In our first few classes we discovered the following math patterns and facts.

1. Any number times 0 equals 0. (Example: 3 x 0 = 0)
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.

Math Trick - Age

Impress your friends with this math trick. Ask the friend to do steps 1-6 on a calculator or piece of paper. Then ask for their result. With the result, you can tell them their age.

1. Pick a number, any number between 1 and 9
2. Multiply this number by 2
3. Add 5
4. Multiply it by 50
5. If the person has already had a birthday this year add 1758. If they haven't, add 1757.
6. Subtract the 4 digit year that they were born.

RESULT: You should now have a number, the first digit(s) being your original number and the last two the person's age!
