Fractions- Ideas for Teaching, Resources for Lesson Plans, and Activities for Unit Plan... - 3 views

  • raction Hunt
    Posted by:lismac #130700

    We walked around the school in small groups armed with cameras and looked for fractions occuring in our school. Each child had to find one scene to capture with the camera. Another group stayed in the classroom and created their fractions with classroom materials. Example- 10 pencils. 9 were yellow and one was red. Then the small groups would come to our computer and insert their picture. Each child then inserted text boxes to type in the fractions. Example- 9/10 of the pencils are yellow. 1/10 of the pencils are red. 9/10 + 1/10= 10/10 They could choose the fonts and colors and such... they used word art to add their names. They loved it! We also do one using multiplication.

  • One activity that went over pretty well with my class was putting fractions in order. After completing a lesson on comparing fractions, each student was given a fraction on a 3x5 card and asked to tape it to their chest. Then they were instructed to line up in order from greatest to least. After they had completed the task, after much deliberation, I informed them of the correct order. They did pretty well considering there were fifteen students.

  • Another thing I did was draw fractions number lines (about seven inches long) on a piece of paper, one under another with enough space between lines so my students could label the points. The first line was not divided. The points were labeled 0 and 1.

    The second line was divided into halves. The students labeled the points on the line 0/2, 1/2, and 2/2.

    The third line was divided into thirds. The students labeled the points 0/3, 1/3, 2/3, 3/3.

    You probably get the idea. The remaining lines were divided into fourths, fifths, sixths, eighths, tenths, and twelfths, and the points were labeled. (It is very...
  • I created an interactive fraction number line from 0 to 2 on my wall. I have about 40 fraction cards with different fractions and I have students take turns putting the cards on the number line. They get the chance to see that some of the fractions are equivelent to others.
  • Well, you are not alone. Fractions lessons sometimes need repeating over and over until they understand the CONCEPTS. Try giving them a mnemonic device to help them remember what to do. My kids decided to use GCF as Greatest Calories n Fat so that's why you REDUCE!! This just helped them to know when to use the GCF but it still needs lots of practice. Also, do a lot of hands-on activities that show equivalency in fractions. Make fraction strips using construction paper, and the kids can show all the equivalent fractions by matching up the strips. Or try the pizza fraction pieces that you can buy. I believe that it just takes lots of fun practice as well as drills on the procedures. Take your time and don't rush through it or you'll be sorry to see that they won't remember any of it by Christmas!!
  • Make up index cards before hand. Group them in 3's (.25 on one card, 1/4 on another, 25% on the third) make up however many sets of three you need to give a card to each of the students in your class. Once the cards have been shuffled, pass one to each student. Have them find their 'family' WITHOUT MAKING A SOUND. When .20, 1/5 and 20% find each other they have to put their cards on a large number line in the front of the class. It's a great way to get them all involved, and gets them up and around the classroom.
  • I also have my student play Fraction Tic Tac Toe, on a 4 x 4 grid filled with halves, fourths, and eighths. They have to make a whole with 3 fractions in a row. They love it!!! I'm not sure where the gamesheet come from, but I am sure you can make your own.

  • Fractions are as easy as pigs
  • One way to help students to understand the basics of adding and subtracting fractions (denominators must be the same; add/subtract the numerators; DO NOT add/subtract the denominators) is to teach the students what the parts of a fraction really are: numbers and names. This also helps combat the frequently-taught but incorrect idea that a fraction and a ratio are the same. A ratio may look like a fraction, but it is not a fraction.
  • FRACTIONS ARE AS EASY AS PIGS

    What is 2 pigs plus 3 pigs? 5 pigs
    (Write as a fraction: 2/pigs + 3/pigs = 5/pigs)
    Notice, we do not end up saying the answer is 5 horses.

  • The top of a fraction is a NUMBER: 1, 2, 3, etc.
    The bottom of a fraction is a NAME: half, third, fourth, etc.
    We can add and subtract numbers. We cannot add and subtract names.
  • Fraction Blackjack
  • Ask each student their "denominator." Don't give it away. Ask each one until one finally says their name. Continue through the room... Their name is their denominator.

    When you practice adding and subtracting fractions with like denominators, actually say "pigs" instead the fraction name. Then say, "Instead of pigs, we are using ..." and let them answer with the appropriate denominator.

    It is fun when doing subtraction to say, "If we have 5 pigs and eat 3 pigs, besides a stomachache, what is left?"

  • The transition to unlike denominators is automatic. If the names are not the same, you can't add the fractions.
    2/pigs + 3 horses is still 2/pigs and 3/horses (unless we discover a "common denominator" -- a common name: farm animals).

    Once the students know they must have a common name (denominator) in order to add or subtract, they have a reason to learn about common denominators.

    By the way, I always begin common denominators without worrying about the Least Common Denominator (LCD). Once they can find a common denominator (multiply the denominators), add or subtract, and then reduce, they can be led to finding "easier" denominators to work with. Students who have too much difficulty with LCD can still get the correct answer; they just have more reducing to do. Those who can find a lower common denominator have less reducing.

    This is a very basic rendering of "Fractions are as easy as pigs."

  • Denominate means: to name
    Political parties nominate (name) their candidates.
    Religious denominations are identified by their names.
    The denominations of money are the names of the coins and bills.
  • One game that my students enjoy the challenge of is Blackjack 1. You need a set of fraction cards per student (or you can make them from index cards.) The same rules as Blackjack apply. Instead of trying to get to 21, they want to try and get close to 1 without going over. With this game they practice addition and comparing -- it's great. You can also make it more challenging or bring in mixed numbers with Blackjack 2 or Blackjack 3. (Blackjack 2 means to try to get as close to 2 as possible without going over.)

    I am not sure where to buy fraction cards. I have one set that I received when I took over a classroom. However, I have always had the students create their own sets and we used them for several games. I gave each students a set of index cards (3 1/2 X 5) and they wrote the fractions in pencil so they couldn't be seen through the cards. These are the fractions we included: all fractions with a denominator of 2, 3, 4, 5, 6, 8, 10, and 12. (To challenge the students you may want to use the 7, 9, and 11 denominators as well.) I also had the students include 2 0's such as 0/3 and 0/4 and two 1's such as 3/3 and 4/4. Each game required two sets of cards, so I had the students write their initials in the corner of their set so they would get a complete set back after the game.

  • Fraction War

    Fraction War with the fraction cards: It is just like the card game of War, but with the fraction cards instead. This game helps students to compare fractions and encourages them to use number sense in comparison before using the algorithm of making equivalent fractions.

    Memory

    Memory with the fraction cards: It is just like the traditional "Memory" game, but any equivalent fractions are considered a match so 1/2 would be a match with 2/4. This game helps them to identify equivalent fractions. You can also play this game with fraction to decimal equivalence by making a set of decimal cards too.

    Fraction/Decimal Bingo

    Fraction/Decimal Bingo: The students have game boards with decimals on them. You call out fractions and if they have the decimal equivalence they can mark it on the board.
