1 The One Penny Whiteboard Ongoing in the moment assessments may be the most powerful tool teachers have for improving student performance. For students to get better at anything, they need lots of quick rigorous practice, spaced over time, with immediate feedback. The One Penny Whiteboards can do just that.

2 To add the One Penny White Board to your teaching repertoire, just purchase some sheet protectors and white board markers (see the following slides). Net, find something that will erase the whiteboards (tissues, napkins, socks, or felt). Finally, fill each sheet protector (or have students do it) with 1 or 2 sheets of card stock paper to give it more weight and stability.

5 On Amazon, markers can be found as low as $0.63 each. (That s not even a bulk discount. Consider low odor for students who are sensitive to smells.)

6 The heavy-weight model works well.

7 On Amazon, Avery protectors can be found as low as $0.09 each.

8 One Penny Whiteboards and The Templates The One Penny Whiteboards have advantages over traditional whiteboards because they are light, portable, and able to contain a template. (A template is any paper you slide into the sheet protector). Students find templates helpful because they can work on top of the image (number line, graph paper, hundreds chart ) without having to draw it first. For more templates go to

9 Using the One Penny Whiteboards There are many ways to use these whiteboards. One way is to pose a question, and then let the students work on it for a while. Then say, Check your neighbor s answer, fi if necessary, then hold up your whiteboard. This gets more students involved and allows for more eyes and feedback on the work.

10 Using the One Penny Whiteboards Group Game One way to use the whiteboards is to pose a challenge and make the session into a kind of game with a scoring system. For eample, make each question worth 5 possible points. Everyone gets it right: 5 points Most everyone (4 fifths): 4 points More than half (3 fifths): 3 points Slightly less than half (2 fifths): 2 points A small number of students (1 fifth): 1 point Challenge your class to get to 50 points. Remember students should check their neighbor s work before holding up the whiteboard. This way it is cooperative and competitive.

11 Using the One Penny Whiteboards Without Partners Another way to use the whiteboards is for students to work on their own. Then, when students hold up the boards, use a class list to keep track who is struggling. After you can follow up later with individualized instruction.

12 Keep the Pace Brisk and Celebrate Mistakes However you decide to use the One Penny Whiteboards, keep it moving! You don t have to wait for everyone to complete a perfect answer. Have students work with the problem a bit, check it, and even if a couple kids are still working, give another question. They will work more quickly with a second chance. Anytime there is an issue, clarify and then pose another similar problem. Celebrate mistakes. Without them, there is no learning. Hold up a whiteboard with a mistake and say, Now, here is an ecellent mistake one we can all learn from. What mistake is this? Why is this tricky? How do we fi it?

13 The Questions Are Everything! The questions you ask are critical. Without rigorous questions, there will be no rigorous practice or thinking. On the other hand, if the questions are too hard, students will be frustrated. They key is to jump back and forth from less rigor to more rigor. Also, use the models written by students who have the correct answer to show others. Once one person gets it, they all can get it.

14 Questions When posing questions for the One Penny Whiteboard, keep several things in mind: 1. Mi low and high level questions 2. Mi the strands (it may be possible to ask about fractions, geometry, and measurement on the same template) 3. Mi in math and academic vocabulary (Calculate the area use an epression determine the approimate difference) 4. Mi verbal and written questions (project the written questions onto a screen to build reading skills) 5. Consider how much ink the answer will require and how much time it will take a student to answer (You don t want to waste valuable ink and you want to keep things moving.) 6. To increase rigor you can: work backwards, use variables, ask what if, make multi-step problems, analyze a mistake, ask for another method, or ask students to briefly show or eplain answers

15 Eamples What follows are some sample questions that relate to understanding measuring liquid volume and masses as outlined in the Massachusetts Curriculum Frameworks that incorporate the Common Core Standards: 3 MD2

16 Eamples Each of these problems can be solved on the One Penny Whiteboard. To mi things up, you can have students chant out answers in choral fashion for some rapid fire questions. You can also have students hold up fingers to show which answer is correct. Sometimes, it makes sense to have students confer with a neighbor before answering. Remember, to ask verbal follow-ups to individual students: Why does that rule work? How do you know you are right? Is there another way? Why is this wrong?

26 Liters and milliliters are metric units used to measure volume the amount of liquid held in a container (beaker, glass, jar, mug, pitcher )

27 What metric units are used to measure liquid volume? Liters or milliliters.

28 What is liquid volume? The amount of liquid in a container like this beaker.

29 What metric unit would you use to measure the liquid in this beaker? Liters or milliliters ML Ounces, cups, pints, quarts, gallons can be used to measure liquids but are not part of the metric system.

30 A liter is about 1 quart. Here are 2 quarts of milk and a liter of ginger ale.

31 A very common size for soda is the 2 liter bottle.

32 How much is a liter? What common object comes in a liter size? A liter is about equal to 1 quart. Milk comes in this size.

33 What size soda is this? 2 Liters Abbreviation: Liter = L (l)

34 For small amounts, you can use a milliliter milliliters = 1 liter Abbreviation: ML (ml) = milliliter A milliliter is very small. 5 milliliters = 1 teaspoon. A milliliter is 1/5 of this. This beaker contains 1000 ml (milliliters)

35 1 ml 1 tsp Often medicine is given in milliliters. When this device if full of medicine it is 1 teaspoon. 1/5 of it is 1 milliliter. A milliliter is very small, you need a special syringe to give an accurate dose. It would be about the amount to fill from the bottom of your thumb to half way up your thumbnail.

36 How many milliliters are in a liter? 1000 milliliters = 1 liter

37 About how much liquid is a milliliter? 1/5 of a teaspoon From the tip of your thumb to half way up to your thumbnail.

38 What is often measured in milliliters? Medicine (you need a special syringe.)

39 About how many more milliliters need to be added to this beaker to make 1 liter? Approimately ml more.
