Turtle Method for Multiplication 4th Grade Math

Oh okay hello today I’m going to show you a
method that I have taught my fourth graders it is called the turtle method
it is a method for multiplying two digit numbers times two-digit numbers let’s
choose a number let’s say we have 37 times 25 the first thing we’ll do is
draw a turtle head this will help us to separate the place values the ones place
from the tens place draw a little turtle a little turtle
mouth and here is your turtle head you’ll see and you’ll understand why
this is helpful as we go through the first thing we’re going to do is
multiply five times seven five times seven is thirty-five
and then your next step is multiply 5 times 3 5 times 3 is 15 plus 3 more is
18 put your 18 down now this is where we’re
going to stop and I want to show you there are some things to remember number
one we’re going to check off the 3 because we will no longer use that so
check is your first step number two we’re going to give a collar to the
turtle and this is going to remind us that we will no longer use the 5 we’re
finished with the 5 and number 3 which is my favorite is laying egg give a
turtle egg which is a 0 underneath the 5 and this is allowing us to remember that
we are finish with the ones place this is the
most common error with fourth graders is forgetting to put the placeholder so
check collar lady egg now if you remember these three things you’re sure
not to fail now we’re going to go on and move to the tens place and multiply two
times seven now remember to criss cross 2 times 7 is
14 2 times 3 is 6 plus 1 is 7 now the final step is to add 5 plus 0 is
5 8 plus 4 is 12 carry your 1 just like always 7 plus 1 is 8 plus 1 more is 9
and your answer to your two digit multiplication is 925 all right are you
ready to try another one let’s try 18 times 43 remember to draw your turtle
head and you will find that as you do this you’ll become faster and faster
that you also checking to do make sure that you’re doing all 3 of your steps 3
times 8 24 3 times 1 is 3 plus 2 more is 5 here we go with our 3 steps check
caller lady egg all right now we’re ready for the tens place 4 times 8 32 4
times 1 4 plus 3 is 7 and then I will do my final step which
is adding four seven and seven all right there you go try one make up a problem
and try one yourself thanks

  1. Oh my goodness I remember learning this last year with you! Just wanted to say thanks for being such a great teacher and I don't know if you remember me but I was in Ms.Woods class last year and I was also in yours .Miss you

  2. Instead of teaching kids this, why don't you teach kids the about the Distributive Property? It's what multiplication is. If you teach kids the concept when they are young, they will already be comfortable with it by the time they get to algebra (because they've had years of practice).
