Life Size Composite Figures

This is a great activity for a cooperative learning group!

I put students into teams of three to four and gave them the challenge of creating a "Life Size Person" using quadrilaterals, triangles, semi-circles and quarter circles.  I helped them cut the shapes with my paper cutter. All they had to do was tell me where to cut and give me dimensions.  I did this so that the cuts would be straight and easier for them to measure.  Yes!  Measure!  They did that also!  They had to find their dimensions and then use the correct formula to find the area.  

All of their work was shown on the back of their "Life Size Person".  (Next time, I will have them show it on the front.) 

All pieces were taped together on the back.  Great conversations took place as students were creating.  I heard one team even say something about using numbers that were easier to divide by two for the triangles, so that they wouldn't have a decimal answer!  That is a pretty clever observation!

Students also discussed which formulas to use, how to use them and my favorite, "you don't have to divide by two because there are two congruent semi-circles that make a whole circle when put together".

Students also discussed the attributes of the shapes used.

The final product had the total area of the composite figure.

If you use this activity in your classroom, I would love for you to share the amazing creations your students come up with on this post.  

Thanks for looking and have a great day!!!

Jenga Math Review

A while back I posted about a used Jenga game I purchased at a Goodwill store.  Well, I finally finished it!  It took me a while because I didn't really know what to use it for or how to fix it up.

Well, I'm finally done and here is the final product!

I used an old plastic bin I had for
storage since the original
box wasn't in good condition. 

They all fit perfectly!

I used fine point permanent markers to make the game colorful.  I included various types of skills that my students need review on. Since the game blocks were in excellent condition and very smooth, it was easy to write on them with markers. 

TIP:  Use brand new fine tip markers.  For some reason, my used markers bled into the wood. 

One of my student groups already tried it out and they said it was "cool"! 

I hope these tips were helpful.  Let me know what you think!

UPDATE:  I was able to get a picture of Math Jenga in action.

I have my students seated in groups of four and I rotate stations around the room by groups.  Many students were anxious to get their turn at this station.  :D

Here is another great test review activity available at my Teachers Pay Teachers Store.
