Pragmatic Mom

– Multiply & Divide (Free Web Games)

Pragmatic Mom was slow to get her oldest to master multiplication facts.  By the middle of third grade, my daughter was tested weekly on multiplication; times twos, times five and times ten were not so hard but then all of a sudden, we had a week to learn x3, then another week for x4, and on and on.  Yikes.  A fast way to learn multiplication was in order.  Luckily, my mom friend was a third grade teacher.  She found that some children learn very effortlessly though song.  These are the skip-counting songs that she taught in her classroom.   Although, my daughter wasn’t that excited to sing these songs, hearing them sung incessantly helped her to master multiplication, and these songs work even better for division.

Skip Counting Songs to Learn Multiplication (and Division)

Times 8 — This is best song.  Sing to the tune of “She’ll Be Coming Around the Mountain”

8, 16, 24, 32….40!

48, 56, 64….72!

8 times 10 equals 80, 8 times 11 equals 88, and 8 times 12 is 96…. Hurrah!  Hurrah!

Times 7 – Sing to the tune of “Twinkle Twinkle Little Star” (which incidentally is the same tune as the ABC song)

7, 14, 21

28, 35, 42

49, 56, 63, 70

Multiplying by 9’s Digit Trick

This link is great because it has great visuals:

1
Spread your hands in front of you

Spread your hands in front of you

Spread out your hands in front of you. Make sure that all ten fingers are showing.

  • 2
    Count out and fold the finger

    Count out and fold the finger

    From the left, count as many fingers as the number you want to multiply nine with. Say you want to multiply nine by four. Count four fingers from the left and then put the fourth finger down.

  • 3

    Count the fingers to the left of the folded finger. In this example, there are three. This is the first digit of your answer. Write it down.

  • 4

    Count the fingers to the right of the folded finger. In this example, there are six. This is the second digit of the answer. Write it down to the right of the number you wrote down in the previous step. In this case, the number will now read 36 or thirty-six.

  • 5

    There you go! You have the answer to the multiplication problem.

    8 x 8 Math Fact Rhyme

    Her teacher taught the class this rhyme that has enabled her 4 year-old brother to master this one math fact (8  x 8):

    I ate and I ate until I threw up on the floor,

    so 8 times 8 is 64!

    Pragmatic Mom also likes flash cards.  The easy way is just to sort cards by what your child knows, and focus on the cards that s/he is learning.  Another slightly more fun way is to pick all the cards out of a box and if you know the card you take it out, if not, put it back.  Keep doing it until the box is empty.

    Free and Fun Multiplication Math Games

    My 4th grade daughter’s teacher sent home these math games.  She plays them daily and she loves them!  Games 2 and 3 are her favorite!

    1.      www.mathmastery.com/cyberchallenge:  This website gives 60 second math fact tests.  When the 60 seconds is up, the student is able to see which math facts they mastered as well as the ones they got wrong.  My daughter thinks this game is boring so start with this one.
    2.      www.iknowthat.com/com/L3?Area=Mathblox:  In previous years, this website has been a class favorite.  It offers each student the opportunity to practice the particular math fact that they are working on.  For example, if a student has trouble with the 5’s, they can consistently practice just that skill.   This is my daughter’s favorite game as well.  It’s great to practice by a particular fact family; I think it’s easier to learn facts this way as well. 
    3.      http://arcademicskillbuilders.com/games/grand_prix/grand_prix.html: This website usually sparks the most interest in mastering multiplication facts.  It offers students the opportunity to host their own car racing game or join in on a car race with others.  In order to get your car moving, you need to gas it up by answering a multitude of basic math fact problems correctly.  It truly is a ton of fun.  My daughter likes this game but the multiplication facts can be easy.  In a race, there might be 5 facts that are times 1.  The game gives you the problems you get wrong, plus this slows your race car down.   
     
    Pragmatic Mom suggests playing three games per session.  Start with game #1 as it’s the most boring of the three.  Next go to game two and work on a particular x factor.  Game #3 is really fun because you race against yourself or other kids.
