## Math — 4

#### You should know all of your math facts. If you don’t, please go to xtramath every day until you do. Math is easier, and therefore more fun, when you know the answers! (Parents: If this isn’t coming easily for your child, you can slow it down. Click on parent/teacher and log in. Choose the child’s tab. Choose Change Program. Choose 6 second addition. When it’s mastered, you can change to subtraction, etc.)

**Course Description: **Students will expand their understanding of graphing, measurement, fractions, decimals, geometry, estimation, place value, time and money. Students will be introduced to adding, subtracting, multiplying, dividing and simplifying fractions, as well as probability, order of operation, the coordinate plane, long division, angles, percents and averages. Students will practice their skills and new math vocabulary using worksheets as well as online games, quizzes and activities. Students will also be challenged by mental math problems.

**Materials:**

- Basic Supplies List
- Day 61, yarn — Really, you could use any type of string. Floss would work; thread is probably too weak.

Note: My family has not used this page yet so the links are untested and it has not been edited.

**00**x 3**0**= 15,**000** - In America we put a comma after every three digits, starting on the far right with the ones. They don’t do that everywhere. I remember being confused when I was first living in Macedonia because in numbers they use decimal points for commas and commas for decimal points.

**Fractions** **Day 51**

- Let’s start with a simple review.
- In the review it pointed out that one half, 1/2, is the same as two fourths, 2/4. What else is it the same as? If you had a pizza with 8 slices and you ate half, how many slices did you eat? 4! Four is half of eight. One way to read fractions is 4 out of 8.
- These are all the same amount.
- one half
- five tenths
- five out of ten
- 0.5
- 50%

- 1/2 , 2/4 , 3/6 , 4/8 , 5/10 are called
**equivalent fractions**. Equivalent means equal. Those fractions are all one half. The top number is half of the bottom number. The**denominator**is two times the**numerator.** - When we change an
**equivalent fraction**to its lowest terms, it’s called**simplifying or reducing**the fraction. That just means we take 5/10 (five tenths) and call it 1/2 (one half). If you ate 5 of the the 10 cookies, you ate one half of them. 5/10 and 1/2 are the*same amount*. - One way to find an
**equivalent fraction**is to multiply or divide the top and bottom numbers (the**numerator**and the**denominator**) by the same amount. Watch this presentation. - Hang the monkeys on the line. Sometimes they will match what is on the number line. Sometimes you will have to hang the monkey on an
**equivalent**fraction, one that equals the same amount but is written with different numbers.

**Day 52 **

- Match the fractions with the pictures.
- Match the equivalent fractions. (Hint: multiply the numerators and denominators by 2.)

**Day 53 **

- Compare the fractions. You compare them by looking at their numerators.
- Which fraction is the largest amount?
- 1/2 is greater than 2/5 because…
- 1/2 equals 5/10 (multiply top and bottom by 5)
- 2/5 equals 4/10 (multiply top and bottom by 2)
- 5 > 4

- Drag the numbers into the answer squares. Use the little buttons next to the answer to check your answer or to show a picture of the problem.
- It will require you to simplify your answers. Do you remember what that means? It means to find the equivalent fraction with that uses the lowest numbers. You do that by dividing the numerator and denominator (the top and bottom) by the
*same*number. If the top and bottom numbers are both even, then you know you can divide them both by two to make them smaller. - Fraction workshop — Click on add mixed fractions with like denominators. Type in 10 for the number of problems.

**Day 138 **

- Fraction workshop — Click on subtract mixed fractions with like denominators. Type in 10 for the number of problems.

**Day 140**

- Play this factors game.
**Factors**are the numbers that can be divided evenly into a number with no remainder. For example, you can divide 24 by 2 and 3 and 4 and 6 and 8 and 12. 2, 3, 4, 6, 8, 12 are all factors of 24. 5 and 7 are NOT factors of 24 because you can’t divide 24 by 5 and get a whole number. You would get a decimal, or have a remainder. - Thinking about what divides evenly into a number will help you simplify your fractions.

**Day 141***

- *Print and complete this worksheet, adding three fractions. If it is an improper fraction (the top number is bigger than the bottom number), divide the fraction to make it a mixed number.
