These Google slides will help your students build decimal sense while Representing Decimals With Base Ten Blocks.
Decimals are a big part of life, especially when it comes to money. And it is super important that we provide our students with lots of different opportunities to build decimal sense. One way we can do this is to get out those base ten blocks…or in this case, have the children play with base ten blocks on Google Slides.
Want other ways to build decimal sense. These Google Slides use number lines and decimal grids to focus on other ways of looking at decimals.
Representing Decimals with Base Ten Blocks
Many children are familiar with base ten blocks. In k – 2 they were used to help children understand whole numbers. They used the cube to represent the one’s place, the long to represent the tens, and the flat to represent the hundreds place.
Now they get to do the same thing, just with decimals. But these slides add a little challenge.
The Changing One
While working through these slides, the students will notice that the block that equals one will change. It provides an extra challenge and will drive home the fact that we are working with the powers of 10….just like they did when they were little.
On this slide, you can see that the flat equals one. This means that the block equals 10, the long equals one-tenth, and the cube equals one-hundreth.
So to solve this problem, they simply copy and paste five longs and place them in the goal.
Things change a little with this one. Now the flat equals one-tenth. So what is the one…the block! The long is now one-hundredth and the cube one-thousandth.
Solving isn’t hard once those facts are established.
To show 2.059 we move over two blocks. We don’t have any tenths, so we don’t have to copy any flats. There are five hundredths, so we copy and paste five longs. And finally, with nine thousandths, we copy and paste nine cubes.
It is that simple. These slides will help children focus on the place value of each digit.
