As we continue the trek we all know
that we need certain pieces of equipment to finish the trek. We could try and
run the race with just socks on, but we would not be able to go on some of the
paths even if we wanted to and the trek would get more and more painful and
frustrating. We need another piece of equipment to make it further into the
trek. Just as we need pieces of equipment to make it along the trek we need
many pieces of knowledge in math to learn how to solve problems. As the
problems get harder we need to add more knowledge (or equipment) along the way
and build on previous knowledge so that students can finish the trek with
minimal strain and frustration. How will you equip your students? Who knows we
just might have a photo finish at the end of the trek where we need to use
tenths, hundredths, or even hundredths of a second!
Last time we talked about place
values. Today we are going to talk about place values with decimals. I am going
to include some of the place values that we learned about before and then add a
decimal into the number.
When you have a decimal in the
number you know that you have a value on the right side of the decimal that is
less than one but larger than zero. Also
note that we do not have a ones place on the right side of the decimal.
The first place value on the right hand side of the decimal is called the
Tenths place. The second place value right of the decimal is the Hundredths
place. Then we have the Thousandths and Ten Thousandths places for the third
and fourth place values on the right hand side of the decimal point. Take a
peek that the chart below. When you watch the Olympics this summer you will see a lot of these numbers!
If you are still having problems
with place values with a decimal please view the video below and then go here
for more information.
Once you think that you have built
onto your previous knowledge of place values and are proficient with place
values with decimals try this fun Pirate Game! Have fun and I will see you all
on the Math Trek!
