Math Teaching Tips Tips 6 to 10
Using Data That Is Meaningful

"Children need opportunities to build and construct graphs that can make sense to them. Graphs help children move naturally from concrete toward symbolic representation of data. The best way to do this is to have students involved in collecting data and formulating questions that lead to problem solving. A good way to do this is to have students keep track of the children who are absent each day class is in session. Graph the information on grid paper that is large enough to be displayed. You can use a piece of white formica board to create a grid that can be used over and over again...draw permanent lines for the grid and then use erasable markers to record data. Use the data to help students formulate questions and develop other math skills such as counting (tallying), place value, percentages, comparing and contrasting, etc. You can adapt this to hair color, height, etc."
"Prepare to Die!"

"I try to do as many projects as I can with my AP classes that will challenge them and excite them at the same time. Last year, I had an idea that worked very well. Albeit, you probably don't want to use this project with kids younger than high school age. But, as a project, I had them finance their own funerals.
My students did not only know how much was involved, but they actually took it a step further on their own for extra credit. They actually proved that it's cost to finance a funeral in our part of California, on the average of 22%, costs more to die than be born.
It may seem a little out there to do something like this, but if you have a few kids that you think can handle it, you can review just about every standard that's written in math. We even use some Calculus."
"Long Division"

"When teaching long division, students often forget what to do next after they bring down a number. Even though you post the steps on the board, they will subtract, bring down and then get confused. I've found that if the students learn to immediately draw a new division symbol around the subtracted number and broughtdown number, it will remind them to divide as the next step."
"Beat The Machine Math!"

"This game really works for just about any subject. I tell my students to buy a voice tape recorder at the begging of the year. I then have students take a stack of flashcards and read them into the recorder. There should be a pause between the problem and the answer of about 57 seconds.
As an example, "3 x 2 = (5 sec. pause) 6."
When students go through all the cards, they should then play back the tape and compete against the tape recorder. If they get the answer right, they get one point. If they get it wrong, the recorder gets a point. The object of the game is to shut out the tape recorder."
Math "Lunch Passes"

"After teaching for 20 years, I finally found a fun way to get my students to tell ME that they need to practice their multiples more! I make up a quick "test" where they must write out the multiples for 710 numbers, in a scrambled order. Then I present the chart to them 5 minutes before lunch, and tell them they will line up in the order that they finish the "test". The first day I present it, I can hear the slower students talking about how they need to study this number or that, as their faster friends go to lunch first. The second day I have fewer slower students, and by the end of the week, the lunch pass can be used on the next needed skill. And they have fun!"
"Twentyfive Positive and Negative Integers"

"I have had problems getting my students to "think fast" when it came to adding and subtracting positive and negative integers. Most of my students are "classified" and have very weak math skills. I don't know where the idea originated, but here is how it went:
I bought regular decks of cards. Enough for the students to get into groups of 34. At first, they used just the red and black cards. Aces counted as number one. Red cards were negative numbers and the Black were positive numbers. They played the game like "WAR". One card turned over clockwise until the total was "Twentyfive". They started slow, but were very involved after 5 minutes. The more they played, the faster they "added and subtracted". When they got proficient, they added the Face Cards. J = 11 Q = 12 K = 13 "
Can HelpNeed Help Signs

"My problem was in teaching math lessons. Students who had trouble understanding the lesson, were shy about verbally asking for help. I came up with the idea of red and green lightbulbs. Each child had a set at their desk. During the lesson, to check for understanding, I might ask the students to hold up the green bulb if they understood and the red bulb if they didn't understand the concepts. When time came to practice the skill, if a student was still at a loss, he would place the red bulb in the corner of his desk. That would let me know who needed my help. What seemed to work best was my green bulb people would pair up voluntarily with the red bulb people for private tutoring. It worked because there was no embarrassing raising of the hands. Those that needed help felt more comfortable and my "green bulbers" were delighted to be the "teacher". This was done on an informal basis and the students might be a green bulb one lesson and a red bulb the next."
Tired of Tardy Students

"I was tired of many of my students being tardy to class. It was a major interruption and although the school has a tough tardy policy, evidently, this isn't enough to stop tardies. So I started what I call the "BellworkTardy Connection". I give all my classes bellwork everyday a few review math problems. The students hate bellwork. So I told the students that for everyday that no one in their class is tardy, they get to "skip" the bellwork for the following day. This has really helped with tardies and has caused the students to pressure their classmates to be on time!"
"Visions of Formulas Dance in our Heads"

"When writing the formula for a quadrilateral, A=bxh put a rectangle around the bxh; for a triangle, A= bxh, draw a triangle around bxh divided by 2 and you have a visuals of the formulas so the students do not get them mixed up!"
"Candy Jar"

"It is difficult at times to keep students on track. I have a huge canister of candies in my classroom that I give out to students who catch me making a mistake, when doing a math problem. I give out the candy to the first person who catches the mistake. If there is a tie, big deal...it's only candy. Anytime I am at the grocery store, I pick up a pack of candy, gum, suckers, etc. You would be surprised at how well the students pay attention. It is a great motivation technique. I have been known to make a mistake or two on purpose."
