The last few weeks we've been busy learning about geometry. We started our unit creating a variety of lines and angles using toothpicks and circle stickers...

We learned the difference between 2D and 3D shapes, defined polygons and quadrilaterals, and identified how many sides, faces, and vertices shapes had on the Smartboard...

Students classified picture cards as congruent or similar...

and used paper shapes to show translations, transformations, and reflections...

One of the fun small group games we did to demonstrate our knowledge of coordinate grids was playing "Gridlock" using coordinate grid charts and dice. Each group rolled dice and plotted the numbers they rolled. Then, the student in each group who formed the most squares by connecting his/her dots won. Click on  Gridlock for free printable game mats.

Other manipulatives we used included unifex cubes which we placed on shapes to find out their area.

And, just as it is every year I do it, the hit of our geometry unit was creating "robots for a top secret NASA Mars mission" using grid paper and perimeter and area coordinates...

(The above robot received sunglasses so he could see on Mars, lol)

Now, it's onward to master fractions!
 Happy learning!


  1. I love the Gridlock game - I'll have to remember that one!

  2. I just added the the link for free Gridlock game mats & directions to the post : )
