Weekly Math Task: Daylight Savings Time Trivia

We created an activity to help your students learn about Daylight Savings Time. Students work on connected devices to answer Daylight Savings Time trivia and math questions. With all 7 questions this would be a great 25-30 minute activity. If that’s too long, you could cut the 5th and 7th problems and make it a 10 minute warm-up.

The activity starts with a simple question to remind them what Daylight Savings Time is. Students estimate how the spring time change will affect when the sun sets. This seemingly simple problem might be harder for some students than you think. You can always remind them that they are about to “spring forwards” because daylight savings time is about to begin.

Spring Forward

– Task 1: Spring Forward Fall Back –

The next task tells students that Daylight Savings Time lasts for 34 weeks. It asks them what percentage of the year this is. Some of your students may need a reminder that there are 52 weeks in the year. As a challenge, you could ask them how many days in the year and make them compute the number of weeks with the scratchpad calculator. It is always good to show your work; students make fewer errors and teachers can see their thought process. That’s why we encourage use of the scratchpad (plus, it is fun to share the student work with the class, and even ask for volunteers).

Task 3 presents some trivia relating to Daylight Savings Time. According to Wikipedia, it was first started as a way to save energy used on lighting. If the sun sets later in the day, people do not need to turn the lights on until later. The goal was to best align when people would be awake with when the sun would be up.

Daylight Savings Time History

– Task 3: Daylight Savings Time History –

Did you know that Arizona and Hawaii do not observe Daylight Savings Time? If you did then you could correctly answer the next task. Students are asked to tap one of the two states on the map that do not observe Daylight Savings Time. When you review this task, feel free to add in a fun anecdote about why Hawaii does not change their clocks. (Hint: they are closer to the equator, making their winter and summer sunset times more similar than in other states. Interesting!) So why not Arizona? You’ll have to read on because task 7 is about why Arizona doesn’t observe Daylight Savings Time.

The next task asks students to compare sunset times between Colorado and Arizona during daylight savings time. You may need to remind students that Daylight Savings Time happens during the summer. In the Winter, Colorado and Arizona both have the same time.

Task 6 explores the interesting fact that the Navajo Nation recognizes Daylight Savings Time while Arizona does not. During Daylight Savings Time, (spring through fall) the Navajo Nation has the same time as Utah, New Mexico and Colorado but a different time from Arizona. For this task, students are asked to sketch a route on the map to show where they would have to change the clock 5 times without turning around. To get 2 clock changes, students draw a line that goes from Arizona to the Navajo Nation (or one of the other states) and back to Arizona. They then need to do this again, ending with one final trip to the Navajo Nation. In the winter, the entire map is on Western Standard Time so there would not be any clock changes necessary.

– Task 6: The Navajo Nation –

The final task encourages students to think critically about energy savings, climate and Daylight Savings Time. A fun piece of Daylight Savings Time trivia is that Arizona does not change their clocks in an effort to save energy. “Whoa? In task 3 we said Daylight Savings Time helped save energy, now you’re saying the opposite!” In Arizona, having an earlier sunset means natural cooling happens faster. This reduces the need for air conditioning in the evening. Since Arizona is so hot, lots of their energy goes towards cooling homes and businesses. This is less true in other places where it is not so hot in the day and cool at night.
Home Energy Use By Sector

– Task 7: Home Energy Use by Sector –

This task gets students thinking critically about how the timing of the sunset relates to home energy use. Students share ideas with a partner and one of them writes their answer on the scratchpad. There are also hints on the scratchpad.

We recommend this activity as a review of Daylight Savings Time or as a fun warm-up just before or after we change the clocks. To preview the activity, click the link below. Or, login to wootmath.com and search for “Daylight Savings Time” in the Shared Gallery.

How to Use Woot Math to Help with Final Preparation

How to Use Woot Math to Help with Final Preparation

Students are constantly struggling with study skills, especially in 9th grade as we start to think about end of year testing. It is difficult to “know where to start,” which is fair, considering there is a lot of material to cover! They are overwhelmed by the information and are still learning how to manage their time.

I was hoping to relieve some of this stress by creating personalized study plans for each student. I know, I know, a lot of you are rolling your eyes thinking, “How will I have time to do this?!” Using Woot Math and a quick worksheet, I was able to make study plans for all three sections of Algebra 1, on the spot, during a 45 minute class period. I know, it is very hard to believe.

In my Algebra 1 classroom, I start preparation by gauging students knowledge. What do my students need to know to be successful? Where are they struggling? What have they mastered? I answer all of these questions with a pre-test using Woot Math! If you want to check it out right away, click the link below. Continue reading to see how I use the poll.

My final is separated into four distinctive units: number patterns, graphing, writing equations, and systems of equations. I took five key questions from each unit and created a set of twenty questions. In class, I had all of the students work on the poll using the “self-pace” feature with automatic feedback turned on. You can see my student’s results below.

woot-math-alg1-review

Once students have completed their poll, they sit with me and we analyze their results using the results page shown above. I quickly count how many they got correct out of the five questions per unit and calculate their scores. Then, working together with me we create their own personalized study plan. I made this very quickly using a word processor.

alg-1-test-plan

I have used study plans in the past and students respond very well to them, and they continually request them. Parents are thankful that their students have a plan of attack to be successful during finals. Special education teachers are grateful for the guidance, not only for the students but for themselves! This allows students to clearly understand where their skills are lacking and where they shine. Also, meeting with students one-on-one to check in before finals is a great way to instill confidence in your students.

This structure knows no limits! Whether you are teaching math, history, science, you could use this as a tool for your classroom! You can add reflective questions to the study plans to encourage students to think about their goals and not just memorize formulas.

How do you prepare your students for finals? Do you let them run free and learn study skills on their own? Or do you have an awesome game that you play? Whatever it is, we at Woot Math would love to hear about it! Good luck studying! Woot! Woot!

Study Time – Fun with Statistics

Task #1

The activity starts with a tap-an-image problem. Students tap the outlier in the data.
 
Task 1: Tap the Outlier

– Task 1: Tap the Outlier –

This is a good refresher if your students are familiar with the concept of an outlier. If they aren’t, it is a good opportunity for instruction. I recommend lingering a little on the context here. Discussing what the data means primes a discussion about hard work and a growth mindset. Although the data is not real, it helps students understand what an outlier could be in a real world context.

Task #2

Task 2 is a review of different types of correlation. We thought it was a weak correlation. Since there is only one outlier, some students may argue that it is strong correlation. After your students submit a response, you can have a discussion by de-selecting the “Reveal Answer” option. Then you can view and discuss the results of the class without revealing the right answer. You can also press the “Assign Groups” button to automatically create groups for small-group discussion.
 

– Assign Groups Feature –

Task #3 and #4

Tasks 3 and 4 both provide an equation of a line representing best fit, and students are asked to determine a test score given study time. They also highlight an interesting feature of the short answer task type. While designing a task, you can set it to accept equivalent forms of the correct answer. Click on the gear icon to set the various equivalence options.

 

– Edit Equivalence Options –

For this task we turned off operations because an answer of 0.1*3+0.5 doesn’t seem like they have quite figured it out yet. If operations were on, the tool would accept 0.1*3+0.5 as a correct answer. We left fractions on because converting 0.8 to a fraction is helpful extra practice. There’s nothing wrong with that.

– Task #3: Accepted Answers –

In the answer blank you can also separate multiple correct answers with a semicolon. As long as the number comes first, the software will give you access to the equivalence tools. If you do a letter or word first, it will treat the answer as a string and let you change the number of typos allowed. The way we have the answer box setup, it will accept responses of 0.8, 80%, B- or any fractional equivalent to 0.8. This way your students will not get it wrong if they think outside the box, interpreting a grade of 0.8 as a B-.

Weekly Math Poll – Systems of Inequality

Task #1
The context of the problem is a business that makes hats, both by machine and by hand. In the first problem, students need to model an inequality between their budget, $2000, and the cost of making each type of hat. Often students don’t know where to start with word problems, so this task provides some supports in the scratchpad. If you think your students don’t need the extra support, feel free to remove it by clicking on scratchpad settings after you have copied the task into your account.

Student view of task with scratchpad

Task #2
The next problem is another opportunity for them to model an inequality from a word problem. Some students may be able to intuitively see that if over 50% are made by hand then y>x. Others will need some help, so the scratchpad has some steps to get them working. When reviewing the problem with the class, you can always use this pre-saved bookmark called “Great Work!” (Note: you can access bookmarks by clicking on the “Bookmarks” tab when viewing results.)

Task #2 with steps illustrated on the scratchpad

Notice how the scratchpad helped the student get started with writing down what they know, then putting it together to solve the problem. If students write the final answer as y/(y+x)>0.5 (or any variation of it) they will get it right, make sure you go over that this is the same as y>x before the next problem.

Task #3
This is a great example of how you can spice up a multiple choice question. There is a pre-made graph and a blank table on the scratchpad to help them connect different representations of y>x.

Scratchpad with different representations of y>x

Task #4
This problem has the inequality from task 3 on the scratchpad. The major advantage of this is even if your students got it wrong in task 3, they won’t be building off a mistake moving forward. If you are running a teacher led poll, they won’t be able to look ahead. This task is harder than the last one, remember to remind them to use a table or plot some points. If you want, you can always add hints on the scratchpad by going to “Scratchpad Setting” when editing the task.

Scratchpad with inequality from previous task on the scratchpad

The final problem gives them practice with testing points in a system of inequalities while remembering the parameters of the original problem. Students are given a graph of the system of inequalities to help them draw connections between different representations. Remind them as they work that they can draw on the graph (using the scratchpad) to plot points and see which of the shaded regions they are in.

Happy Pi Day 3.14 – Quizzes & Resources

Pi Day celebrates the mathematical constant (π), as March 14 can also be expressed as 3.14, the first three digits of pi. Pi is the ratio of a circle’s circumference to its diameter, which is a constant. That is – for any size circle, the ratio is the same (π).

Happy Pi Day

 

The first large-scale celebration of Pi Day was organized by Larry Shaw at the San Francisco Exploratorium, where Shaw worked as a physicist. Then in March 2009, Pi Day became a national holiday in the United States. And a fun note? March 14th is also Albert Einstein’s birthday. Don’t worry, unlike Pi, this history lesson won’t go on forever. Onto the math!

Use these two warm-ups or exit tickets
