Math Riddle of the Day

If www.matcheez.com offers T-shirts from their Family Tee Collection in just 30 different colors, how many different combinations of shirts could we purchase for our family IF we have 5 family members? (Remember that order matters since each family member wears a different size.)

HINT
If you can't remember how to do combinations and permutations, try experimenting with just 5 colors and 3 family members then look for the pattern.
Here is an example to get you started:
If the shirt colors are red, blue, yellow, green, orange then Mom can wear 5 different colors of shirts for every shirt that dad can wear. This means that there are 25 different shirt combinations. What happens if we add in a baby who can also wear 5 different colors of shirts for each combination that Mom and Dad can wear?

Baby Sign Language


One of the hottest trends in child development is teaching your baby Sign Language. The popularity is new but the concept is not. My dad taught me to fingerspell and to count in ASL before I went to Kindergarten. Although he has been partially deaf in both ears since he was a teenager, his hearing loss is generally unnoticed by those around him. I do remember attending church services for the Deaf. My dad wanted to expose us to Deaf culture and give us opportunities to practice using American Sign Language. When I later became a teacher, I frequently used fingerspelling to help beginning readers who were struggling with their letters and older readers who were struggling with spelling. I found that the kinesthetic experience of using Sign Language improved their memory and the hand signs for each letter gave them a visual connection between the "alphabet song" and the printed letters on a page.

When my oldest child was a baby, I read a wonderful article in the Spring 1995 issue of Mothering Magazine about using Sign Language to communicate with your baby. I was inspired and taught my daughter a few basic signs including "more," "milk," and "mom." She first used signs at 7 months old and began forming simple sentences at 12 months. This was helpful because although she jabbered constantly, none of the words made sense. Sign Language helped alleviate much of the frustration we might have otherwise experienced during this stage of child development.

When my second child was born, I was given a book called Signing is Fun by Mickey Flodin. It is a pocket size paperback book with great drawings. I had forgotten many of the signs I learned as a child and this little book served as a nice reference that I carried in my purse.

More recently, at a family reunion, my cousin's 18 month old daughter was demonstrating the various American Sign Language signs that she had learned. I was impressed that she knew over a hundred signs rather than the 15 or so that I had taught my children as toddlers. She had learned sign language from watching a program called Signing Time. I decided to purchase a set of Signing Time DVDs for my 1 year old son as a Christmas gift. We love the songs and the simple animation is cute. The Signing Time DVDs are wonderful because they include an explanation and demonstration of each sign followed by children, toddlers and even babies demonstrating the sign. My son loved to watch the other children sign and began imitating them immediately after watching the first program.

Learning new signs is easy. I sit my baby on my lap and we watch the Signing Time DVDs together. We listen to the CD in the car and practice the signs while we drive and sing. My older children enjoy learning the signs along with the baby. The Signing Time web site offers games to improve signing skills along with resources for parents and caregivers. Our family's signing abilities are improving as we use signs to communicate with each other daily. I can quietly talk to my children in church without disturbing others. I even use Sign Language to talk to my husband across the grocery store. My oldest child once used fingerspelling to send me messages while she was in the dentist chair and unable to speak.

My youngest is growing quickly. As his oral speech becomes clearer, he has begun to express a desire to learn more signs. He sometimes invents his own signs for words he does not know. This gives us an excellent opportunity to look up the actual signs. We use a terrific online dictionary provided by the Michigan State University Communication Technology Laboratory.

Unfortunately, I have had well intentioned family members forcefully voice their concern that my children's abilities to communicate in English would be hampered by using sign language. I have never known quite how to gently explain to these individuals that quite the opposite is true. Our family's experience with Sign Language has been overwhelmingly positive. Scientific
research
shows that children who use Sign Language have earlier language development than their peers. Teaching American Sign Language has never been shown to hinder speech or vocalization. Children who use signs have larger vocabularies and higher IQs. They also have fewer tantrums (presumably because they can ask for what they need and want.)

Try using a few signs with your own children or grandchildren. The time it takes is minimal and the benefits are outstanding. You might find, as we did, that your toddler is trying talk to you but you simply aren't understanding the words he is using. Signing gives young children a "voice" with which to communicate their feelings and needs. Once you experience the fun of teaching your Baby Sign Language, the practicality of signing with your children and the joy of communicating with your toddler in a language you can both understand, you too will want to share the magic of Baby Sign Language with other parents.

Educational Shows Worth Watching

Not all "educational" shows are worth the airtime that they occupy. Here are a few of my favorite math shows:

Cyberchase
http://pbskids.org/cyberchase/
This PBS show does name Hacker as the "bad guy" but aside from that, it is an excellent show. National math standards are addressed. Concepts are clearly presented. Ideas build from the simple to the complex. Real-life connections are included at the end of each episode. Besides it's a cartoon and it's FUN!

Math Monsters
http://www.mathmonsters.com/
This is my favorite educational show. It is a cartoon series produced with the National Council of Teachers of Mathematics. This is reflected in its goals, teaching methods and concept presentation. My children love to watch it over and over. Appropriate for ages 3-9.

Mathematics is Elementary
http://www.ait.net/products/mathematics/
A good series for home-school students as a supplementation for a basic program.

The Number Crew
http://www.thenumbercrew.us/
This series is a claymation show for very young children and focuses on basic number concepts.

Ms. Math
http://www.cptv.org/msmathhome.html
This series is intended for parents and teachers who wish to help their children understand the beuaty of mathematics. On demand video is available.

Check your local public TV station to see times and airdates.

Product Review-School House Rock

Today's product recommendation is School House Rock.

My own parents never let us watch Saturday morning cartoons so I missed these neat, educational featurettes. My own children love this DVD. It is a compilation that includes Grammar Rock, Money Rock, Science Rock, Multiplication Rock and America Rock. Disney has also included several "bonuses"- long lost songs/never before released songs/songs newly written for this special edition/etc.

Two of the volumes on this DVD hold importance for teaching math: Multiplication Rock and Money Rock. My son knew his mutiplication facts for twos, threes, fives and tens by the time he was 4 years old. We didn't use flash cards. We didn't take timed tests. He just watched the Multiplication Rock section on our School House Rock DVD. We would sing the songs in the car and at the breakfast table. The simple words and catchy rhythms helped him memorize his "times tables." Money Rock is loads of fun. The songs help children understand the basics of money. My personal favorite is Tyrannosaurus Debt.

In order to ensure that your child gets the full benefit of this DVD, I suggest the following:

  1. Watch the songs with your children. Learn which are their favorites.
  2. Sing the songs during the day. All of the lyrics are available online, if you want to print out a hard copy to carry with you.
  3. Help your children make the connection between what they have heard and what they are doing at school. If a teacher sends home flash cards for the "3 times tables," remind your child about the song. Lay out the flash cards in order. Then help them sing, "Three is a magic number. Yes, it is, it's a magic number..." Chant "3-6-9, 12-15-18..." and point to the corresponding flash cards.
  4. Watch the DVD frequently. The advantage that a DVD format has over the old VHS format is that you can easily select individual songs to view. These mini movie segments were originally intended to be viewed during commercial breaks. Let your children watch one or two when there are just a few minutes until school, dinner or bed time.
  5. If you prefer, purchase just the CD and let your children listen to it in the car, in bed and during meals.

At some point, nearly every child will be required by their elementary school teacher to prove that they have memorized their multiplication facts. This DVD and CD collection can give your children a jump start.
