This Week's Work : Week 8 -- for Inquisitive Young Mathletes

Assignment 1:
Using Algebra and Number Sense as Shortcuts from Mathcounts Mini

Watch the video and work on the activity sheet below the video on the same link for more practices.

Also, review the following:
$$x^{2}-y^{2}=\left( x+y\right) \left( x-y\right)$$ $$\left( x+y\right) ^{2}=x^{2}+2xy+y^{2}$$ $$\left( x-y\right) ^{2}=x^{2}-2xy+y^{2}$$ $$\left( x+y\right) ^{2}-2xy =x^{2}+ y^{2}$$
$$\left( x-y\right) ^{2}+ 2xy =x^{2}+y^{2}$$
$$\left( x+y\right) ^{2}-4xy =\left( x-y\right) ^{2}$$

Assignment 2:

Pascal's Triangle  from Math is Fun

Pascal's Triangle and Its Patterns

Assignment 3:
It'll be sent through e-mail.
Happy problem solving !!
