Middle School Hero's Projects
Hero Day Celebration
Class of 2013 Career Day Trip

The month of June has been full of celebrations!  Students used technical drawing & coordinate geometry to create a portrait of their Heros.  We used the coordinate grid to draw an identical image of the hero.  Students shared their projects on our Hero's Day celebration.  

Another celebration was a Career Day Field Trip.  This trip was made possible by Gear Up Chicago.  Students won prizes for team building activities and learned about careers.

How do you find the side length of a square when you know the area?   Area of a square is side times side.  For example if the area is 25 cm² and 5 x 5 = 25, the side length = 5 cm. 

Square roots are found using the perfect squares.
1² = 1            √1 = 1           Square root of 1 = 1
2² = 4            √4 = 2           Square root of 4 = 2
3² = 9            √9 = 3           Square root of 9 = 3
4² = 16         √16 =4           Square root of 16 = 4

Can you find the square roots for 25, 36, 49, 81, 100, 121, and 144?  What patterns do you notice?
