Technology in Mathematics Education
This week Education Week featured an article about technology in mathematics education where I was quoted a couple of times. The gist of what I had said was the while technology is crucial in supporting mathematics learning, it is not in and of itself a substitute for quality teaching and curriculum materials. Something not mentioned in the article (which I understand does not have room for everything) was my concern that teachers are not being given enough time to for professional development to not only learn about new technology tools and resources but also to learn how to design and implement learning activities with these.
In case you have the time and interest, here are a few articles and tutorials worth exploring about exciting tools to support mathematics teaching and learning!

Algebra Distribute multiplication of two binomials by using foil method
We now discuss in Algebra section. The topic is Distribute multiplication of two binomials by using foil method.
The FOIL Method come from the words "first", "outer", "inner", "last".
Here FOIL stands for: (x + 4)(x + 5) Where, both 'x' are the first element, 4 and second x are the inner element, first x and 5 are the outer element and 4 and 5 are the last elements.
In a Foil Method, multiply the first terms in each of the parentheses, then multiply the two terms that are on the "outside", then the two terms that are on the "inside", and then the last terms in each of the parentheses.
Now i should multiply two binomials we using distributive law, and then combine like terms. When multiplying (a + b)(a + 5b), we should follow the steps
1. Apply Distributive Law : a (a + 5b) and b(a + 5b).
2. Simplify the expressions to a2 + 10ab and ab + 5b2
3. Add like terms in the expression and your answer is 6a2+ 31ab + 35b2

Parallel and Perpendicular lines
If two lines are represented by equations y1 = m1x1 + c and other is y2 = m2x2 + c, then m1 and m2 represent their slopes. It both the lines are perpendicular to each other then m1m2 = -1.
For example, 2y + x = 4 and 2x + y = -5 are perpendicular lines.
