### Making Pretzels—Do the Math

Tuesday, April 26 is not only Hug a Friend Day, it's also National Pretzel Day. So let your students make pretzels (or toast frozen ones) and share a fun snack together as they learn about tally charts and graphs.

Excel Math Lessons help build students who are confident in mathematics and prepared for higher-order thinking skills and advanced math education. In fact, many students develop a love for math as they progress through the Excel Math program. Take a look at our proven lessons for Kindergarten through Grade 6 at www.excelmath.com. More than just worksheets, these lessons really work! Read the glowing reports from administrators, teachers and parents:

Now let's make some pretzels and try some edible math. Have your students wash their hands. Give each student a small sheet of parchment paper or foil and a small piece of bread dough (you can use refrigerated bread or biscuit dough or make your own). Provide cookie sheets, an oven or toaster oven, oven mitt, kosher salt, and a permanent marker. Also provide gluten-free dough or pretzels for students who have gluten allergies.

Let each student initial one corner of his parchment paper or foil sheet. Have him roll the dough into a thin snake shape. Then hold one end of dough in each hand and place it on the parchment paper or foil as if to form an oval. Twist the ends together as shown to form a pretzel shape as shown:

Some students may prefer to leave their pretzels as sticks or to give them a curved look. Others may want to create their own unique design (heart, face, initial, etc.). Sprinkle the pretzels with salt. Give each student a wet wipe to clean up messy hands and also to wipe down the work space. After shaping the pretzels, point out that the pretzel ends look a bit like arms reaching up to give yourself a hug. Let your students demonstrate crossing their arms to give themselves a hug.

Place the pretzels in a 350-400 degree oven (or toaster oven) for 8-12 minutes or until golden brown. Let cool and then serve. Hand out napkins. (You could also provide assorted mustards for dipping or cinnamon sugar to sprinkle on top, and water or juice to drink. Or bring melted chocolate, vanilla yogurt and mini pretzel twists to create covered pretzels. These are a bit more messy. Make sure none of your students have allergies to the ingredients.) If you like, bring hard stick and twist pretzels and do a taste test to see which type of pretzels your class prefers. Create a class tally chart to keep track of how many students prefer hard vs. soft pretzels. You could also show stick vs. twist preferences. Depending on which types of graphs your class is studying, have each student make a bar graph, a picture graph or a circle graph showing the class preferences for pretzels. Here's a Tally chart we created:

Have your students create their graphs using pencil and paper. Once you check them for accuracy, let the students get creative and use an online charting or graphing website to create a 3-D look and add color and text to the graph. The online graphs can be printed, emailed, or embedded on your class website. Here's a bar graph created from ChartGo.com:

Create your own chart or graph

The National Center for Education Statistics also has some free charts and graphs for students. This pie graph (from http://nces.ed.gov/nceskids/createagraph/) uses the same data as our bar graph above:
While your students enjoy the pretzels, talk about how math is used in our everyday lives —financial, measurements (length, distance, volume, temperature), computing, modifying recipes, cooking, listening to music, sports, medicine, carpentry, etc. Students who finish their graphs early can create a poem describing some of the enjoyable ways they (or their parents) use math.

### Running a Marathon and Celebrating Patriot Day

The Boston Marathon happens each year on Patriot Day. On Monday, April 18, Boston will hold its 120th marathon and residents of two states will have a holiday for Patriot Day, extending the due date for filing their taxes until Tuesday, April 19.

The Boston Marathon is the world's oldest annual marathon. It has distinguished itself as the pinnacle event within the sport of road racing by virtue of its traditions, longevity and the fact that entry into the race is via qualification.

So how long is a marathon? Take a guess and we'll reveal the distance below.

Next week security will be extra tight for the marathon. Spectators planning to watch the Boston Marathon from anywhere along the course should expect a significant presence of uniformed and plain clothed police officers.

In 2015 drones were banned along the entire Boston Marathon route for the first time in the history of this race.

Spectators approaching viewing areas on the course, or in viewing areas on the course, may be asked to pass through security checkpoints.

Memorial wreaths have been placed around Boston in memory of the victims of the bombings that took place during the race three years ago.

In 2014, Rita Jeptoo of Kenya set a women's course record when she finished in 2:18:57. The men's course record was set in 2011.

Excel Math uses the back of most tests to introduce students to multi-paragraph word problems.

Some of these story problems revolve around sports events such as a marathon, bike race, skating, sledding, walk-a-thon, swim meet or a basketball game.

Eventually, students begin creating word problems of their own. These are called "Create A Problem" exercises and help to merge math with literacy. Here's a Create A Problem page from Excel Math Grade 2.

The answers are given in bold type, as shown in the Teacher Edition. Take a look at Lesson samples from Excel Math on our website: https://excelmath.myshopify.com/

To answer the initial question, a marathon is 26 miles 385 yards (26.21875 miles)  or 42.195 kilometers. The states that celebrate Patriot Day are Maine and Massachusetts.

### 4-4-16 Square Root Day

On 4/4/16 we celebrate Square Root Day. The date of this unique day changes depending on the year.

For example, the last time we had a day of this kind was on 3/3/09.

Square Root Day only comes around once in a great while—whenever the month and day are square roots of the year, such as 5/5/25 or 6/6/36.

Some suggestions for enjoying square root day include finding the square roots of various numbers, rooting around to create a succulent garden or soaking an avocado seed in water to watch the roots grow, cooking up some root vegetables, square dancing, squaring off for a contest, or anything else involving squares or roots.

Serve a snack of square crackers (hand out 4 to each student and let them eat as many as necessary to leave the square root of 4). Provide gluten free crackers for students who may be allergic to gluten.

Also serve cheese cubes. Give each student two cubes and ask them to square that number and write down the answer on a piece of paper.

Do the same with 3, 4, 5 and 6.

If your students need help multiplying, let them try some Online Basic Fact Practice for a fun way to practice addition, subtraction and multiplication.
Excel Math lessons give students lots of practice learning basic math facts, solving word problems, working with decimals, and much more.
