Math Lesson 3 Step by Step Instructions 3 Level A: Converting Liquid Measurement 1 K. Choih 3 2008 Converting Liquid Measurement (2 hour class lesson) CASAS Competencies: " CASAS Scale Levels: 181 3 200 " 1.1.7-5 Identify product containers and interpret weight and volume Outcomes: " Learners will be able to change units in the customary system. Specifically, the learner will convert units of liquid capacity including: fluid ounces, cups, pints, quarts, and gallons.
" Learners will be able to convert from larger to smaller units and vice versa. Teacher Preparation and Materials: " Containers and liquid measurement cups/glasses in cup, pint, quart, and gallon size " One gallon of apple juice " 8 oz. paper cups for learners (16 8 oz cups are used in the lesson 9s Warm Up).
" One gallon of water " Precut cThe Gallon Man d parts 3 use different colored paper for each part " One tape dispenser for one or two pairs " Copies of Worksheet 1, 2, and 3 Why? Introduction/Warm-up: Discuss the importance of liquid measurement: for preparing food from a recipe, for determining how much food to purchase for a party, etc. Demonstrate how to convert from larger to smaller liquid ... more. less.
measurement units and vice versa using a gallon of juice and at least 16 8 oz.<br><br> cups, and extra cups if there are more learners. Step by Step Do: Give learners a cup. Say: I have a gallon of apple juice here.<br><br> Here is an 8-ounce cup. How many cups do you think we can get out of this gallon juice? Why?<br><br> As learners are calling out numbers, write the different numbers on the board. Okay, let 9s find out if anyone guessed the answer. Pour each learner about 8 oz.<br><br> in his/her cup. How many cups are there? There are 16 cups in a gallon.<br><br> So, for this class, did I buy enough apple juice for everyone? Should I have bought more? Did I get too much juice?<br><br> Should I have bought less? Math Lesson 3 Step by Step Instructions 3 Level A: Converting Liquid Measurement 2 K. Choih 3 2008 What?<br><br> Using the containers that are cup, pint, quart, and gallon size, ask students if they can identify the unit size of each container. Ask students what size containers they have bought or usually buy at the store and what kind of liquid is in the containers they buy. Step by Step Today we are going to take a look at the different liquid measurement units and how to convert from one measurement unit to another.<br><br> Just as you saw with the apple juice, if you know how many people you have to serve drinks to, you can choose from either a smaller or bigger unit containers. You won 9t have too much or too little. First of all, what is liquid?<br><br> What are some examples of liquids? Write cliquid d on the board and any learner responses. Yes, we will be talking about how to measure liquid amounts.<br><br> So then, how can we measure liquids? Write any units (containers) that learners mention on the board. Then the next question is, what does cconvert d mean?<br><br> Provide some time for learners to respond and write cconvert d on the board. After learners get a chance to respond, have them repeat the word, convert, several times. Convert means to change from one unit of measurement to another.<br><br> A good example is what we just did. How many cups did we get from the gallon of apple juice? Yes, 16 cups.<br><br> We just converted one gallon to 16 cups. We changed the gallon unit of measurement to a smaller unit of cups. Are gallons and cups the only liquid measurement units?<br><br> What are some other units that you may know of? What kind of liquids do you buy at the store? What are the names of the different size containers that tell us the liquid amount?<br><br> Write any responses on the board. Teacher should provide any units that are missing. Do!<br><br> As the different containers are taken out and placed in front of the learners and the learners try to identify them, write the units mentioned on the board. Once all of them are said, turn to the board and have learners repeat each word several times. Controlled Practice: Using the different unit containers, make a conversion chart.<br><br> Have learners pour water into cups/pint/quart/gallon containers. Pour two cups into a one pint container, two pints into a one quart Math Lesson 3 Step by Step Instructions 3 Level A: Converting Liquid Measurement 3 K. Choih 3 2008 container, four quarts into a gallon container and so on.<br><br> You can do the reverse by dividing the water in a quart container into two pints, and so on. As the learners are measuring water from/into different containers, write on the board the conversion chart. 2 cups = 1 pint 2 pints = 1 quart 4 quarts = 1 gallon (1 cup = 8 fluid ounces) Explain when to multiply and when to divide when converting the different measurement units.<br><br> Smaller unit to larger unit divide Larger unit to smaller unit multiply Pair/Group Practice: In pairs, have learners create cThe Gallon Man d. Give each pair a set of precut Gallon Man parts. Teacher should model taping the body parts on Mr.<br><br> Gallon one the board. Once the Gallon Man is complete, review the conversion chart. Individual Practice: Handout Worksheet 1.<br><br> Students work alone on the first 7 questions. Students can find a partner for questions 8 and 9, if they 9d like. Students who finish before you are ready give the assessment, Worksheet 2, can work on Worksheet 3, a word find exercise.<br><br> Step by Step Controlled Practice: Using the container props, ask learners if they know which measurement units are used for each container. Math Lesson 3 Step by Step Instructions 3 Level A: Converting Liquid Measurement 4 K. Choih 3 2008 Here are some containers of different liquid measurement units.<br><br> Ask one of the students to put the containers in size order from small to large or large to small. Thank you. So the smallest container is called a cup.<br><br> The next one is a pint. This is a quart, a half-gallon, and the largest is a gallon. Have the gallon of water ready.<br><br> Now, let 9s find out how we can convert, or change, from one unit to another. Have each learner or pairs (depending on how many measuring cups are available) measure a cup of water using measuring cups/glasses. Make sure the water level is at eye level.<br><br> You may need to lower your head for a more accurate and better reading. Show learners how to read the measuring cup. How many ounces does a cup have?<br><br> Help learners with the reading. Do you think we can pour both cups into this pint container? Hold up the pint container.<br><br> Could you both pour your cup of waters into this pint container, please? Likewise, have learners measure water first hand and combine or separate the water using various containers. Teacher provides various amounts to combine or divide into.<br><br> Let 9s try how many cups go into one pint. Let 9s try how many pints go into a quart. Let 9s try how many quarts go into a gallon.<br><br> Ask learners again for the different conversion information and write it on the board. 1 cup = 8 ounces How many ounces in a cup? 1 pint = 2 cups How many cups in a pint?<br><br> 1 quart = 2 pints How many pints in a quart? 1 gallon = 4 quarts How many quarts in a gallon? etc.<br><br> This is how liquid measurement is converted. We can use multiplication or division when converting to different units. When we change a larger unit into a smaller unit, we multiply.<br><br> We are cutting a big piece into smaller pieces, so we need to have a larger number of smaller pieces. Math Lesson 3 Step by Step Instructions 3 Level A: Converting Liquid Measurement 5 K. Choih 3 2008 When we change a smaller unit to a larger unit, we divide.<br><br> We are combining several smaller pieces together to get a larger piece, so we need a smaller number for the bigger piece. On the board, write the conversions using multiplication or division. 1 cup into ounces 1 x 8 = 8 ounces 1 pint into cups 1 x 2 = 2 cups 2 cups into pints 2 ÷ 2 = 1 pints 4 cups into pints 4 ÷ 2 = 2 pints 8 quarts into gallons 8 ÷ 4 = 2 gallons etc.<br><br> We do need to remember which numbers to use when we are converting. Next, we are going to do an activity that will help you remember the numbers that you need to use when converting from one unit to another. Students are to be paired and given tape.<br><br> Hand out a set of cThe Gallon Man d parts that have been precut to each pair. Pair/Group Practice: We are going to make cThe Gallon Man d using different parts of liquid measurement units. Each body part will be represented by a measurement unit.<br><br> If the units are connected, that means that they are equal, the same. Let 9s start with Mr. Gallon 9s head in (color).<br><br> Teacher models the activity by taping Mr. Gallon 9s head on the board. The cGallon d in (color) is the middle part of the body, the torso.<br><br> Please tape his torso to his head. His torso will be 1 gallon. Teacher also tapes the torso (gallon) part on the board.<br><br> Next, Mr. Gallon needs some arms and legs. How many total arms and legs should Mr.<br><br> Gallon have? We will use the 4 (color) quarts for his arms and legs. Teacher tapes the 4 quarts, 2 arms and 2 legs.<br><br> What we just taped is just half of the arms and legs, the part between the shoulder and elbow and hip and knee. Did you know that the lower part of our arms and legs have 2 bones? So, now we need to tape 2 of the (color) pints to each (color) quart.<br><br> Teacher tapes 2 pints to each quart completing the arms and legs of Mr. Gallon. Next are the hands and feet.<br><br> We have 5 fingers and toes, but Mr. Gallon isn 9t quite human. He 9s a lot like us but he only has 4 fingers and toes.<br><br> Math Lesson 3 Step by Step Instructions 3 Level A: Converting Liquid Measurement 6 K. Choih 3 2008 But we have 2 bones here, so we are going to connect 2 fingers and toes to each lower arm and leg bones. Teacher tapes 2 (color) cups to each pint pieces.<br><br> Now we can use Mr. Gallon 9s body parts to convert different liquid measurement units. Here 9s a gallon.<br><br> Point to Mr. Gallon 9s torso. How many quarts in one gallon?<br><br> How many quart pieces are connected to the gallon piece? How many pints in one quart? How many pints are connected to a quart piece?<br><br> Teacher asks other basic combinations. Using Mr. Gallon, can you tell how many pints are in a gallon?<br><br> Teacher points to all the pint pieces connected to the quarts and then to the gallon. How about how many cups in pint/quart/gallon? After learners seem comfortable answer questions, have the learners ask questions to others in class.<br><br> Individual Practice: Handout Worksheet 1 (students should work alone for the first 7 questions. They may find a partner for questions 8 and 9). Learners who finish before you are ready give the assessment, Worksheet 2, can work on Worksheet 3, a word find exercise.<br><br> So what? Assessment: Use Worksheet 2 to assess student understanding of liquid measurement. Discussion: Ask learners what they might be able to do with the information learned.<br><br> Why do you need to know the different liquid measurement units?
