# Math — 4

### Found a problem? Check here.

#### 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: This site will require a free account. 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
• Lesson 61, yarn — Really, you could use any type of string. Floss would work; thread is probably too weak.

Lesson 1 (Materials: It’s not needed today, but I suggest that this year they have a math notebook, a spiral notebook or something, unless they have a lot of trouble with physically writing. If they do, you could see if they like an online scratch pad better.)

Welcome to your first day of school! I wanted to give you one important reminder before you begin. Many of your lessons below have an internet link for you to click on. When you go to the different internet pages for your lessons, please DO NOT click on anything else on that page except what the directions tell you to. DO NOT click on any advertisements or games. DO NOT click on anything that takes you to a different website. Just stay focused on your lesson and then close that window and you should be right back here for the next lesson. Okay?

Parents:

1. If you didn’t get here through My EP Assignments, I suggest you go there and create an account.
2. This course has an offline version and a printables workbook. Go to the top of the course page for book links.

Please decide about buying books or printing out the worksheet packets for the year. You’ll want those worksheets available when they come up in the curriculum. Scroll up above Lesson 1 to see the book options.

• 458 x 34 = 500 x 30 = 15,000
• In the US, 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 writing numbers they use decimal points where we would use commas, and commas where we would use decimal points. That’s how they do it in Europe.

2. Solve the word problems. Make sure you write the label on your answer: 12 apples, \$4.50, 6 children, etc.

Fractions

Lesson 51

2. 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? Four! Four is half of eight. One way to read fractions is 4 out of 8.
3. These are all the same amount.
• one half
• five tenths
• five out of ten
• 0.5
• 50%
4. 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.
5. 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 out of the 10 cookies, you ate one half of them. 5/10 and 1/2 are the same amount.
6. 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.
7. Choose equivalent fractions. Play with it to make equivalent fractions. How are they made?
8. Choose Reduce Fractions. You are going to find an equivalent fraction by dividing the top and bottom by the same number. If the numerator and denominator are both even, then divide by 2. Then see if you can do it again. If the numerator and denominator both end in either 0 or 5, then divide both by 5. If the numerator or denominator could both be divided by 3, then divide both. You are finding equivalent fractions.

Lesson 52

1. Identify the fraction that doesn’t match the picture. One fraction shows the fraction in the picture. One is an equivalent fraction. One doesn’t belong. Which one?
2. Match the equivalent fractions. Choose Level 1. I suggest slow relaxed mode.
• If the fraction is 1/3, then look for a picture that shows one out of three parts colored in.
• It may have 3 out of 9 squares colored in, but notice that it has one out of three lines colored in. 1/3 and 3/9 are equivalent fractions.
• 1/3 is 3/9 reduced.

Lesson 53

1. Compare the fractions. You compare them by looking at their numerators.
2. Which fraction is the largest amount? Choose level 10.
• 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
• You can also try to picture which is bigger. One of out five slices of a circle, one fifth, is not as much as three out of four slices of a circle.

Lesson 54*

1. *Complete the worksheet.

Lesson 55

Lesson 56

Lesson 57

1. Read about mixed numbers or mixed fractions and do the questions.

Lesson 58*

1. When you work with fractions, you need to always reduce your answer. That means that you want your answer to have the smallest numbers possible. You may add to get 3/9 as your answer. But then you should stop and see if there is an equivalent fraction with smaller numbers. If the denominator and numerator are both even, then you can divide the top and bottom number each by 2 in order to reduce it. Then check to see if you can reduce it more! 3/9 can be reduced to 1/3 by dividing the numerator and denominator both by 3.
2. Learn about reducing, or simplifying fractions.
3. Choose reduce fractions.
4. Remember that you ALWAYS should reduce your answers when working with fractions.

• Label the times.
• Change the PM times to 24 hours by adding the 12 hours that has passed in the AM. 1PM is the 12 hours of the AM + 1 hour passed in the PM = 12 + 1 = 13:00.

Fractions

Lesson 136

1. 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. So that means that the numbers 2, 3, 4, 6, 8, 12 are all factors of 24. The numbers 5 and 7, for example, 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.

Lesson 137

Lesson 138

1. Fraction workshop — Click on “add fractions with the same denominators.” Do 10.
2. You need to simplify your answers. Do you remember what that means? It means to find the equivalent fraction 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.
3. Do ten more using mixed fractions with the same denominator.

Lesson 139

1. Fraction workshop — Click on “subtract fractions with like denominators,” ones that are the same.
2. Complete ten.
