Name: Lindsey Gramman EDEL 200 Sec 004/Group B1

Email Address: lrgramman@bsu.edu

Classroom Teacher: Mrs. Walker Grade 5

Lesson Objective: The students will make a chart of pictures from magazines they use in their everyday life that would be weighed using ounces/grams, pounds/kilograms, and tons placing the units from smallest to largest and grouping like units together.

IN State Standard: Standard 5- Measurement

Students understand and compute the areas and volumes of simple objects, as well as measuring weight, temperature, time, and money.

IN Indicator: 5.5.5

Understand and use the smaller and larger units for measuring weight (ounce, gram, and ton) and their relationship to pounds and kilograms. Example: How many ounces are in a pound?

Content:

• Understanding the smaller and larger units of measuring weight.

• The relationship between ounces, grams, and tons to pounds and kilograms.

Materials/Media: poster, blank sheets of paper, pictures to go on the poster, book: A Weighty Tale, my computer for the power point and song, scale, objects to weigh on the scale: paperclip, whole pineapple, 5 quarters, dollar bill, slice of bread, 2 pears, a picture of a car.

• Motivation

• Sing this song along with computer, bring copies for all.

“So there’s 16 ounces in a pound And 2000 pounds in a ton Now imagine a 10-pound cat on the ground Who loves to lounge in the sun What is the weight of the cat in ounces? (That’s tough!) Maybe but that’s the way the ball bounces. 16 ounces multiplied by 10 pounds (160 ounces, how does that sound?) You look confused, you just need more practice To keep all your math skills sharp like a cactus Here’s another one, you’re almost done A 4000 pound car is how many tons? 4000 pounds is 2 tons exactly (That’s a heavy car, is it a truck or a taxi?) 2 tons is right, you’re really coming along Learn the standard system by learning this song”

• Ask..

How many of you have a cat?

Do you know how many pounds your cat weighs? If none of the students have a cat, how many pounds are a different type of animal that the child has?

If your cat/animal weighs that many pounds, how many ounces do you think your cat weighs? (multiply by 16)

In the song it said two tons is 4000 pounds exactly, how many pounds is one ton?

Goal for Learner: Today we are going to learn the relationship of pounds, ounces and tons to grams and kilograms. At the end of the lesson I am going to have you make a chart of items you would use on an everyday basis that you would weigh/measure using the units that we will talk about arranging them from smallest to largest in groups.

• Procedure

New Information: Show PowerPoint.

• Introduce the meaning of weight and mass. (Weight of an object is the force of gravity that pulls down on the object. On the moon, there is no gravity so an object that weighs 6 pounds on earth may only weigh one pound on the moon.) (Mass is the amount of material makes up an object. Mass stays the same wherever it is and doesn’t depend on gravity.)

• There are two different systems in the world for measuring weight and mass. There is the Standard System that we use in the US and there is the Metric System that people use around the rest of the world.

• The standard system contains the units: pounds, ounces, and tons which measure weight, based on gravity. The metric system contains the units: grams and kilograms which measure mass, based on comparing it to already known mass.

• An ounce measures the weight of very small units. Items you would measure with ounces are a slice of bread, a small bird, quarters, or pieces of chocolate.

• Pounds weigh more than ounces. It is usually what unit of measure doctors will use when you go to weigh yourself at a doctor’s appointment. Some items that you would use pounds for is a soccer ball, animals, people, babies, furniture, dog food, and more.

• A ton is the biggest unit of measurement in the standard system. Some items you would weigh with tons is a car, whales, giraffes, a house, or even a large buffalo.

• In the metric system the smallest unit of measurement is grams. You would use the gram measurement to weigh things like a paper clip, an almond, a dollar bill, or a snail.

• The biggest unit of measurement in the metric system is kilograms. Some things that you would weigh using kilograms are Twizzlers (in a whole bag), picture frames, candles, and many more.

• 16 ounces in a pound.

• 2,000 pounds in a ton.

• 1,000 grams in a kilogram.

• There are 2.2 pounds in a kilogram and 28.35 grams in an ounce. Therefore, kilograms are more closely related to pounds and ounces are more closely related to grams.

• The smallest items you would weigh would be measured in ounces/grams and the items in between would weigh pounds/kilograms. The items you would weigh that you think would weigh the most, you would use tons.

Check for understanding

What is weight?

What are the two systems called that we use to measure weight?

What in the metric system is similar to an ounce? A pound?

What are some other objects you could measure with an ounce/gram? A kilogram/pound? A ton?

What are the smallest units of measurement? (grams and ounces)

What is the largest unit of measurement? (tons)

How many ounces are in a pound? (16)

How many pounds are in a ton? (2,000)

How many grams are in a kilogram? (1,000)

If there are 16 ounces in a pound, then how many ounces are in 5 pounds? (80)

How many ounces are in a ton? (32,000)

Guided Practice: During this the students will make predictions of what unit of measurement they will use for certain items that I brought in. After their predictions I will have them weigh their items using grams/ounces, and kilograms/pounds. They will do this with a scale that I will bring in.

Modeling: Predict what unit of measurement I would use then weigh one of the items I brought in on a scale. I will show them that if I put a paperclip on one side, I would not put a pound of weight in the other side. I would use a gram.

Checking for understanding: Observe the students as they work with the scale to see if they understand the different measurement units. Ask which items are lighter than others. Ask which items are heavier than others.

New Information

Read the book A Weighty Tale.

Go back through the book and see what pictures they have for each measurement.

Check for understanding:

• Did this book help you understand more about which unit of measurement you would use to weigh certain things?

• What are some of the things you noticed in the book that we talked about in the power point?

• What were those certain things measured in?

Practice: Give each student 12-15 cut out pieces of paper (both words and pictures on the papers). On the top of their own paper there will already be the labels in the correct order from smallest to largest (grams/ounces to tons). I will point out which units are grouped together and how they’re in order. After they do that, they will place the remaining of their cut outs on their paper where the item corresponds with the weight shown. For example, they will put the picture of a car underneath the tons label.

Modeling: I will show the students that the labels (words) go on top and the pictures go underneath the labels. I will then show how to glue the cut outs onto the paper.

Checking for understanding: Observe students as they work to see that they have a clear understanding. When they are finished, we will go through their papers as a group to see if they placed all of the cut outs in the right places.

Assessment

• Have students write on a blank piece of paper (will be provided) items that they use every day that would be measured/weighed using pounds/kilograms, ounces/grams, or tons.

• The students will make their own version of a chart like the one we used in the hands on activity with new items underneath the labels. The students will put the labels from smallest to largest on the top of their paper. They will then find the new pictures that correspond to those labels in magazines that I will bring into class.

Closure: We have all learned a great deal today and everyone did a fantastic job! I am proud of every single one of you! To review what we have learned today, what is weight? What is the heaviest unit of measurement? What is the lightest unit of measurement? How many ounces are in a pound? Which metric unit is similar to pounds? Which metric unit is similar to ounces? Now you all know that when you travel outside of this country, you will be able to verify that kilograms relate to pounds and grams relate to ounces when measuring items! This will make all your travels go very smoothly.

Extension: The students will use the scale to measure out more items. These items can include anything they have on them, rings, necklaces, bracelets, erasers, pencils, their Ipad, any items around our group that would not interfere with other groups.

• Evaluation

For assessment the students made their own chart with different items that could be grouped into each individual units of measurement. They also put the units of measure from smallest to largest.
