Musings on Kids' Money and Math

Of Slugs and Budgets – Teaching Money Management to Kids

When my oldest son, Nathan, was four years old, I caught him crying silently in bed one night. I had gone back into his room to tuck him in as he liked to spend a few minutes “reading” to himself before saying goodnight. Seeing him crying concerned me.

“Nathan, what’s the matter?” I asked.

He lifted the book he had been reading and turned to the page where a cartoon representation of a slug was sitting behind a ticket booth. The sign read: Hugs and Kisses $1.00 50¢ 25¢ 05¢. The book he was sharing with me was called The Unhuggables: the truth about snakes, skunks, spiders, and other animals that are hard to love.

“He looks so sad,” Nathan sniffed, pointing to the slug, who did, indeed, look pretty sad. “No-one wants to give him a hug.”

Not being a huge fan of slugs, myself, but relieved that this was what made him upset, I had to quickly figure out what purpose slugs served.

“Oh, honey,” I stalled, “Slugs are misunderstood. They’re actually quite useful. They decompose a lot of dead leaves and that’s a very good thing because it puts nutrients back into the soil which helps flowers grow. But not many people know this otherwise I’m sure they would be giving him hugs and kisses.”

I actually impressed myself that this little bit of information about slugs surfaced in my brain. I guess I really was listening in biology class. And the good news is that hearing this seemed to satisfy Nathan.

“We should tell people that slugs are good,” he said.

“Yes, we should,” I agreed. Five minutes later, he was asleep.

Budgets are like slugs. They’re often misunderstood. And because of that, people find them unhuggable.

But budgets actually serve a very important function. Budgets help us get the things we want in life: a new car, a house, college education for our kids, more time with our family, the ability to travel to exotic places… Money is the tool that can help us achieve those desires. A budget helps us use that tool effectively.

So teaching our kids how to budget is important if we want them to achieve their goals in life. Kids budgeting? Of course! The good news is, teaching them is pretty simple. Here are three ways to give your kids hands-on experiences with budgeting (excerpted from the book Raised for Richness):

The Birthday Party – ages 7+

Decide how much you are willing to spend on your child’s birthday party. Get CASH in that amount (that’s your budget) and put it in an envelope labeled ‘(Sara’s) Birthday Party’. You’ll use the envelope to help you keep track of your running expenses.

Then have your child help you make a list of all the expenses related to the party. Making a list will help you stay focused when you’re shopping. And thinking of these in advance will teach your child to be organized. She’ll need to consider number of guests, party games, food, party favors, paper plates, etc.

Now the fun part…you get to go shopping. As you buy items, write the total on the envelope and keep a running balance. Using cash will underscore the value of a dollar (it makes a difference if you can SEE the money) and help you stick to the budget.

Tweens and teens can go a step further and come up with the “flow” of the party…when to play games, when to eat, etc.

Clothing Allowance: Tweens and Teenagers

This is a great back-to-school-shopping activity, but can still be used any time of the year. Tweens and teens are quite capable of shopping for themselves. They may make mistakes along the way, but those are great learning opportunities. So giving them a lump sum of money and putting them in charge of spending within the limits of a budget is good practice.

Just like the birthday party activity, begin by deciding how much you’re willing to spend on clothing. Consider how long you expect those clothes to last. In other words, are they shopping for all their fall/winter clothes? Then have your child make a list of needed items: 2 pair of jeans, three t-shirts, socks, warm jacket, etc.

Again, get CASH in the needed amount. Tell him that he needs to buy all the items on the list and any money left over is his to keep! This usually gets kids to think carefully about their purchases and look for good deals. Instant savvy shoppers!

The Cell Phone: Teenagers

Parents have been handed an unbelievable tool to help teach teens how to budget. It’s the cell phone. Yup, that object of love and hate. Done correctly, it becomes an object of learning. Here’s how.

Teens need to stay connected to their friends. This is normal as they figure out their place in the world. Cell phones keep them connected. Using their “need” for a cell phone as the motivator, we can teach them basic money management skills such as budgeting and paying bills.

First, teens need to know that along with a cell phone comes responsibility. Keeping track of your cell phone, resisting the urge to text during dinner, and paying your phone bill. Kids paying bills? You bet! And the best time to teach them is while they are still hanging out with you.

Next, it’s important to establish what part of the phone bill your child will be responsible for. For example, you may pay the family plan fee but maybe your teen pays the additional phone line fee, texting, and upgrades…

Now comes the fun part. Kids learn to budget their money in the context of something the love…their cell phone! Upgrades? They pay. Overages? They pay. Lost phone? They pay. Unpaid bill? No phone. See how simple it is? Okay, so it’s going to take a few months before everyone understands how the whole thing works, but when that happens, it’s a thing of beauty. Kids are happy; as long as they budget their money correctly, they stay connected to their friends. Parents are happy, their kids are learning real life skills. It’s a win/win.

Although a lot of parents are willing to pay for their kids’ cell phones because it offers peace of mind, how about the peace of mind that comes with knowing your child is ready to take on the financial challenges that await her out there? Don’t miss this silver platter opportunity. With teens, when you get the chance, take it!

Sum of Interior Angles of Triangles

This is a super easy, super fun activity where students discover the interior angle measurements of different polygons. I start with the triangle (see photo) and then have them work in groups to prove other interior angle measurements.

Collaboration and communication in the math classroom is so important and this is an easy way to do it. Teams can then do a 1-2 minute presentation which helps develop their public speaking skills.

Common Core State Standards in Mathematics – Geometry

Why give students the definitions? Why not give them enough information so that they can create the definitions on their own? The Common Core state Standards in Mathematics along with the National Council of Teachers of Mathematics Standards emphasize allowing students to be actively involved in creating their learning. Through this, they will learn to:

-reason abstractly and quantitatively
-construct viable arguments and critique the reasoning of others
-attend to precision
-look for and make use of structure

Besides, the reason I like to teach this way is that it’s waaaay more fun and the learning is deeper. It’s a win/win.

Really, Texas? No calculators?

I just read that the Texas State Board of Education is getting rid of calcuators in the elementary grades. It’s a good thing, too, because I’ve no doubt that every kindergarten through fifth grade teacher hands their students calculators so that these teachers can get out of doing what they love doing…teaching.

Honestly.

Although not approved yet, it’s only a matter of time. Because, as we all know, politicians know best. And, yes board members, you are politicians.

I remember my first year of teaching in 1987. I had a set of calculators in my classroom. I found them in the cupboard left by the teacher who’s room I had taken. One day in the teacher’s room during lunch I mentioned the calculators. The entire room turned and stared at me. Turns out, I had the only set of calculators the school owned and, unbeknownst by me, they had been looking for them for months. Considering where Texas is heading, I guess we were pretty lucky to have that one set.

I love calculators. They should not be removed from the classrooms. First of all, kids LOVE them and any good teacher knows that you don’t dismiss what kids love. You figure out how to weave it into your curriculum.

Here’s why I love calculators. They provide excellent opportunities to practice number sense and estimation skills…skills we adults use countless times during the day. Even board members.

Give this one a try: Enter the number 65. What is the fewest number of steps you can take to get the display from 65 to 35? Can you picture the kids doing the math in their heads to see if they can do it in one step?

Or how about: What two numbers under 20 multiply to get 255? What is the fewest number of tries you can do it in?

Priceless oportunities. And ones that good teachers will not be willing to give up.

When my oldest son was in preschool he asked me how many days there were in a year. Now, because he had an elementary math teacher as a mom, he was pretty savvy about things like adding and subtracting. He was also quite familiar with a calendar and knew there were 12 months in a year.

So, instead of telling him the answer, I asked him how he could use the calendar to figure it out. He quickly realized that if he added all the months together he would arrive at the answer.

“And how would you do that?” I asked.

He grabbed that awful cheating tool, the calculator, and proceeded to flip the calendar adding together the last number in each month. By the time he got to the end, his calculator read: 365.

“So how many days are there in a year?” I asked.

“365,” he replied.

And that was the end of that. He problem-solved his answer. He was four years old.

But here’s the thing. He didn’t know how to do double-digit addition. What he did know, though, was that he needed to perform addition in order to arrive at the answer. He understood the concept, not necessarily the specific skill needed. And, hey, as far as I’m concerned, the concept is the important part.

Here’s another example. I was teaching fourth grade and we were doing a math project where we were building a scale model town. One group of diehard football fans convinced me to let them build a stadium. After some consideration, I decided to allow them to do it using a different scale than the rest of the class. At one point they were trying to figure out how many people would be seated in each of the stadiums’ sections.

“How would you figure it out?” I asked.

“We need to divide but we don’t know how to divide large numbers.” We hadn’t gotten that far in the curriculum, yet.

But you know where this is going. “Use a calculator,” I replied. They did, and, like my oldest son, they got their answer.

Shame on those Texas board members who think that, given a set of calculators, teachers are going to have their students do their work through punching in numbers. Really, Texas? Really?

The Artistic Side of Math – Tessellations

I love M.C. Escher! I have a whole book on his work and love to share it with my students when we’re studying angle measurement.

That’s because we’re going to tie math and art together through modifying polygons similar to how M.C. Escher did it in some of his paintings. It’s all about tessellating shapes and angles.

Using pattern blocks, I show students how shapes tessellate. See photo below. Then, I have students determine the angle measurement of each of the pattern block angles. The key is understanding that there are 360 degrees in a circle.

<
From there, I show students how to take a square and cut each side corner to corner, slide it to the other side and tape. We do that again on the other side to create our tessellating shapes.

It's not unusual for students to create two or three shapes to see which one they like best. They determine this by tessellating their shapes (tracing them) on paper. Some students add details just like M. Escher, while others simply color in the shapes. I've also done it using construction paper. See red and green tessellation at top.
