Here is the link to the Function Number Cruncher - that we used in class.

Integers. Here is a cute video with an introduction to integers, and here is another. Skip the intro, then click on Lessons, and then on the integer lesson.

This link gives you the integer rules, and has a story (The Party in Mathland) to help you remember them.

This game is about ordering integers - it gets really fast!

You can practice adding and subtracting integers here, using an interactive board. Have fun!

To work on Integer Addition in another way, use this Color Chips Addition applet; then you can move on to the Color Chips Subtraction applet. Make sure that you know and understand the Integer Rules.

 

We have covered Surface Area, and now we need to think about Volume. Let's look at this interactive which helps us calculate both of these.

We are now investigating solid shapes. Look at the properties of Prisms, and then at the properties of Pyramids. Make sure that you can tell the difference between a square/rectangular pyramid, and a triangular pyramid by clicking on the links. On this page, you can revolve a 3D shape, and mark/count all its faces, edges and vertices.

Pi Day Songs.

Listen to a rap about reciting Pi., or here is another version with different images - the digits of pi receding into space. Here is the other song - the Number Pi Challenge

What is a tessellation?

First, we can make some very simple tessellations here.

Then we can move on to make tessellations where the orientation of the shapes can change. Many artists use this technique with much more intricate shapes than regular polygons.

You can try this yourself on the shmuzzle web page.

One of the most famous artists who used this technique was M. C. Escher, and we can see some of his work on-line. (Look at this Lego version of one of his most famous pictures!)

We will make some less intricate shapes for our own tessellations, using a technique similar to this one. We can try this interactive shape-maker to get the idea.

And finally, just for fun, here are some animated tessellations!

 

 

With FCAT sneaking up on us, it is a good idea to review how to grid FCAT answers using this powerpoint presentation.

Here is an interesting introduction to ratios. You can also watch this little video about unit rates.

This Fraction Pieces web site will help you with improper fractions.

On this site you can review what fractions mean.

For an explanation of converting units in the metric system, try this one at purplemath. We will use this template to measure ourselves using the metric system. Here is a Frames of Reference page to help you relate the metric units to real life.

 

Some of you might want to spend some time practicing long division. Coolmath4kids has a colorful page with the basic instructions. Kidsnumbers has a game called Snork's long division, where you actually do the division, but you get hints and help. Or you can remember range of levels.

Here is the Funbrain Measurement Game - practice using both customary and metric rulers.

You can play with mean, median and mode (measures of central tendency) or you can listen to the Central Tendency song.

Here are some web sites to help you with coordinate pairs:

This is simple but fun - see how long it takes you to feed Billy Bug 10 time/

On this one, do some simple math to find the coordinate pairs - plot them to find the picture.

Here, just match points with pairs

To study perimeter and area, we will work with the Geoboards .

Here is the equation pan balance that we used in class.
