4th Grade Math
Unit 6 goals:
4.NF.5 Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100. For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.
4.NF.6 Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
4.NF.7 Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.
Questions to guide our learning:
How are decimals and fractions related?How can I model decimals using the base-ten blocks?
How can I write a decimal to represent a part of a group?
How does the metric system of measurement show decimals?
How are tenths and hundredths related?
What role does the decimal point have in our number system?
When can tenths and hundredths be used interchangeably?
When we compare two decimals, how do we know which has a greater value?
When you compare two decimals, which digit is the most important?
How does the value of the digit change from tenths to hundredths?

Math Challenges!
I will try to post new challenges weekly or as needed for those kiddos that get done early and/or need an extra challenge in class!
#1 Self-extend your current problem solving. Use the worksheet in class or make your own. Check to make sure you have done each item:
- Did you explain your thinking and how you solved your problem?
- Did you figure the problem out in more than one way?
- Did you make the numbers larger to make the problem harder?
- Did you create your own own problem similar to the current problem?
#2 Research about fractions
Create your own questions about fractions.
Research to find your answers.
Create a project to share your learning.

#3 Math Vocabulary Menu: Choose one activity to do for this unit’s vocabulary. Put a check in the box once you use that topic. For each unit within one nine weeks, you have to choose a different choice. You have the whole unit time to complete your project. Choose from the vocabulary list above.
#4 Pickle Math:
Go to the pick math website (http://mathpickle.com) and pick a puzzle or project to solve. If you need to print a worksheet, let Mrs. Germaine know.

#7 Explain Everything:
Create a video through Explain Everything. Use the app to explain a fraction concept such as equivalent fractions, improper and mixed numbers, adding and subtracting fractions, ordering fractions, comparing fractions, measuring using fractions, or your own idea! You can also use it to explain a concept that you are learning about. Let Mrs. Germaine know when you are finished so we can share with the class.

#8 Keynote:
Use the Keynote app to create a game to practice a fraction concept such as adding and subtracting fractions, making equivalent fractions, comparing fractions, changing mixed numbers to improper fractions measuring with fractions, or anotehr concept.
You can also use it to explain a concept that you are learning about.
