### Giving Students Feedback in Your Math Class

New math standards are asking teachers to facilitate discussions and encourage collaborative problem solving among students in the math classroom.

Giving students effective feedback and helping them to "explain their thinking" will let you determine their depth of understanding. It will also give you a chance to clear up any misconceptions before moving on to more difficult concepts.

Excel Math lessons have discussion questions and teaching tips built into the Teacher Edition for Kindergarten through Grade Six.

Create A Problem Exercises begin with Grade 2 and provide a template for students to write and solve their own word problems, merging math with literacy. In Excel Math we suggest the teacher help students verbalize the problem-solving strategies they use as they solve problems.

Describing the process can help their classmates understand that at times there can be several correct ways to solve one problem. Remind your students to show their work as they solve the problem so if they have errors in the solution, they can find and fix them more easily.

Explain that making mistakes and correcting them is the way to improve and learn. Excel Math includes a unique CheckAnswer system beginning in Grade 2 that lets students check their own work. Most of the time, students can find and correct their mistakes on their own.

When they need more help, a parent or teacher can help them work through the problem to find the correct answer.

Here are three steps to giving students effective feedback:
1. Ask if they understand the question or problem:
a. What information are they trying to obtain? Have them circle the question.

b. What information have they been given? Have them draw a line under the information that will be needed and cross out the information that will not be needed.

c. Do they have the information that they need to get the answer? Find out if the information they have is enough to answer the question.
2. If there is not enough information, ask the student to tell you what information they would need to answer the question or solve the problem.

3. If there is enough information, ask the student to tell you if they underlined the correct information that will be needed. Did they underline too much or little information to solve the problem? If so, have them fix it.

After following these three steps with your students, try using questions and statements rather giving answers when someone is having trouble remembering what to do to solve a math problem. You could ask:
What do you think you need to do first to find the answer?
Do you understand what the question is asking? Tell me in your own words. (This is a good place to make sure any vocabulary words used in the problem are clearly defined and understood.)

What steps should you take to find the solution?

Show me how you figured that out.

Tell me about the problem-solving strategy you used.

What other ways could you have solved this problem?
Take a look at the strategies you use to give your students feedback.

Do any of them need to be modified? Could you use the buddy system to have students help each other find the solutions? Share your suggestions in the Comments box below.

### Happy Mole Day!

Know the math behind chemistry? Then you’ve likely heard of Avagadro’s number (6.023 × 1023) that’s used as a basic unit of measure in chemistry.

This number is more commonly referred to as a mole.

Mole Day is observed on October 23rd from 6:02 am to 6:02 pm, and can include anything mole related.

Activities can range from eating guacamolĂ© to making a felt mole, experimenting with molecules, or researching the creation of mola textiles. The punnier, the better.

Here's a colorful framed mola our relatives picked up in their travels to Panama. The mola or molas is handmade textile art native to the islands of Panama.

Using the fabric of their choice, students can make a small stuffed toy mole to help them remember that a mole in chemistry is actually 6.023 × 1023.

See our blog post from several years ago for a creative felt mole pattern:
Celebrate Mole Day In the Classroom

In  Excel Math, we help students apply math to everyday life. For over 40 years, Excel Math has help students excel in math. In fact, schools that use Excel Math see improved test scores and high student engagement with elementary mathematics—even after the first year!

Here's what teachers and administrators are saying:
"I’ve used Excel Math for many years . . . and loved it!  In Laredo, Texas, I started using Excel Math with excellent test results. Each year produced 95% to 100% of the students passing their Texas State Tests. This also includes the two years I taught in Houston. I’m currently in Oklahoma, and will again use Excel Math with my 4th graders.
I was nominated and won Teacher of the Year for my school campus, Hoover Elementary. I completely believe this happened because of the EXCELlent Math program you provide!!! I’ve used Excel Math for many years . . . and love it! I’m VERY excited to use this program again, and can’t wait to compare the scores from last school year to this. Thank you so very much!!"
— Susan Vilar, 4th Grade Teacher, Hoover Elementary School, Tulsa, OK

### Base Ten Pumpkins for 10/10

Print a set of cards for each student or have them share the cards.

Provide acorns, pumpkin seeds, buttons or raisins for counters.

Or have each student cut the pumpkin shapes from an extra set of cards.

 Pumpkin Seeds

This is a great way to welcome in the harvest season with math!

Complete instructions and colorful patterns are included in the Free Base Ten Cards PDF file.

You may want to roast some extra pumpkin seeds and salt them slightly so your students can snack on the seeds while doing the math.

Excel Math lessons for Kindergarten through Grade 6 have an intricate spiraling process that helps math concepts "stick".

Students learn math for the long term when they use Excel Math.

And because math concepts stay in front of students on a regular basis, they are able to retain concepts from week to week, month to month, and year to year without drill and kill and without having to cram for the test.

Schools using Excel Math see test scores rise, even the first year after Excel Math is used.

Here's what one teacher told us:
"I love Excel Math! Some of my slower students were so excited about the CheckAnswer component. I was surprised and pleased by their response. I could see their confidence improving right away!"

— Jennifer Price, 4th Grade Teacher, West Virginia

### Every Day Should Be World Teachers' Day!

October 5 is World Teachers' Day, a time set aside to honor and thank teachers.

According to recent research, top-notch teachers help students succeed.

This comes as no surprise to most educators.

Effective teachers can boost the test scores of students who have previously struggled.

However, one day a year just doesn't seem enough to properly thank those individuals who have mentored and guided a generation or more of our children.
Here at Excel Math, every day gives us a chance to recognize educators.

This month we're giving teachers a FREE Glossary of Math Terms in English and Spanish to thank you for the time and effort you spend educating, nurturing and challenging students.

Feel free to copy the Glossary for your students and colleagues.

Let us know how long you've been teaching and what ages you teach in the comments box below.  Continue reading . . .

### Celebrating Pythagorean Theorem Day!

Any day is a good time to celebrate math, but today's date can actually be written as a mathematical theorem!

Pythagorean Theorem Day occurs any time the date aligns to the Pythagorean Theorem.

This theorem suggests that for any right triangle with with sides of length a, b and c:
a2 + b2 = c2

The date Aug. 15, 2017, when written as 8 - 15 - 17, can be used to form the triangle side lengths 8, 15 and 17.

We can use those lengths to write the Pythagorean Theorem:
82 + 152 = 172

Check this by doing the math to see if the solution is correct: 64 + 225 = 289
Can you figure out when the last Pythagorean Theorem Day was held?

Can you guess when the next one will be?

With Excel Math, students gain confidence in math. Math concepts build on each other in an intricate spiraling process.

This approach helps students see that math concepts are related and progressive.

Excel Math lessons introduce students to new concepts while reviewing previously-taught concepts. These proven lessons give students an opportunity to master the old, while being challenged with the new.

Students work with a variety of math concepts each day. They tackle a variety of word problems. They learn to evaluate and solve problems, rather than perform algorithms by rote.

Students receive immediate feedback on their progress through Excel Math’s unique CheckAnswer system.

All of this for just \$12 per student for an entire year of lessons and tests! Download an order form here.

Help your students build confidence in math and retain math concepts for the long term with Excel Math for Kindergarten through Grade 6.

Take a look at sample lessons and download sample packs on our website.

The last Pythagorean Theorem Day was just last year: 1/15/16
The next one will be in three years: 12/16/20
