How to take notes and actually USE them! Ms. Ricco

Why are your required to take notes? Notes are meant to be a resource for you to use often when you are learning new material. Notes define key terms that you need to know in order to use math language correctly. Notes provide step-by-step instruction on how to solve math problems and why they are solved that way. Example problems are given in notes to guide you when you are to solve problems on your own.

Contents of your notes Definitions and examples of new terms. Review of old terms. Detailed, step-by-step instructions on how to complete the new concept. Multiple example problems demonstrating the step-by-step process.

How to use your notes Your notes are meant to be used any time that you do not remember how to solve a problem. Step 1: Identify the concept of the topic that you are working on. Step 2: Located in your notebook or binder the section in which you have taken notes on that concept.

How to use your notes (part 2) Step 3: Identify an example problem from your notes that is similar to the problem you are stuck on. Step 4: Follow the step-by-step instructions for how to solve that type of problem. Step 5: It is always good practice to check your answers.

Let’s practice! I am going to provide a sample of the type of lesson that will given in math class. Act as if this is a normal lesson and take the notes and work along with the example problems. If you already know this topic, that is great! But please participate in the activity to get practice.

Converting Measurements Objective: I can convert between centimeters, meters and kilometers using multiplication and division. Vocabulary Convert – to change from one form to another. Metric system – the universal system of measurement used throughout the world. (In England and the United States this is not the metric system is not typically used.

Converting Measurements Centimeter Meter Kilometer 1.0 cm = 1.0 cm 1.0 cm = 0.01 m 1.0 cm = 0.001 km 1.0 m = 100.0 cm 1.0 m = 1.0 m 1.0 m = 0.01 km 1.0 km = 10,000.0 cm 1.0 km = 100.0 m 1.0 km = 1.0 km This conversion table will help you convert from one unit of measure to another because you know the relationships between units.

Using the Conversion Table (Method 1) Example: How many centimeters are in 7 kilometers? Method 1: Step 1: Identify the relationship between units. Since we are going from kilometers to centimeters, we pick the conversion where the kilometer is 1 and centimeters is on the other side of the equal sign 1 km = 1,000 cm

Using the Conversion Table (Method 1) Example: How many centimeters are in 7 kilometers? Step 2: Replace the ones from the conversion table with the value given in the question. 1 km = 1,000 cm becomes 7 km = 7,000 cm *You have found the answer! 7 km = 7,000 cm*

Using the Conversion Table (Method 2) Example: How many centimeters are in 7 kilometers? Method 2: Moving the Decimal Step 1: Identify the relationship 1.0 km = 1,000.0 cm

Using the Conversion Table (Method 2) Example: How many centimeters are in 7 kilometers? Step 2: Take note of how many spaces the decimal moves and in which direction in the relationship you identified in step one. 1.0 km = 1,000.0 cm the decimal moves three numbers to the right.

Using the Conversion Table (Method 2) Example: How many centimeters are in 7 kilometers? Step 3: Replace the 1 in the conversion table relationship with the value you were given in the question. 1.0 km = 1,000.0 cm becomes 7.0 km = ? cm Step 4: Move the decimal the same number of digits in the same direction as you identified in step 2. 7.0 km = 7,000.0 cm

Let’s try another! (Method 1) Example: Billy has a card that has a perimeter of 0.40 meters and he wants to decorate the border with stickers that are 1 cm. How many stickers will he need? Step 1: Identify the relationship from the conversion chart. 1.0 cm = 0.01 m

Let’s try another one! (Method 1) Example: Billy has a card that has a perimeter of 0.40 meters and he wants to decorate the border with stickers that are 1 cm. How many stickers will he need? Step 2: Replace the values from the conversion chart with the values from the question. 1.0 cm = 0.01 m becomes 40.0 cm = 0.40 m Answer is 40, 1 cm stickers

One more! (Method 2) Example: Kayla wanted to put a fence around her yard that had a perimeter of 0.5 km. How many meters of fencing does she need? Step 1: Identify the relationship 100.0 m = 0.1 km Step 2: Count how many spaces and in what direction the decimal moves. From km to m, the decimal moves three spaces to the right

One More! (Method 2) Example: Kayla wanted to put a fence around her yard that had a perimeter of 0.5 km. How many meters of fencing does she need? Step 3: Replace the 1 with the value you know So 1.0 m = 0.1 km becomes ?m = 0.5km Step 4: Move the decimals the same amount of spaces identified in step 2 So 0.5 km = 500.0 m

Your turn! Remember, choose whichever method you like the best and follow all of the steps. Both methods will get you the correct answer!
