1. a. A Geometric Investigation of (a + b)^2
    b. http://illuminations.nctm.org/ActivityDetail.aspx?ID=127
    c. Math
    d. In this activity it is helping you understand the use of (a + b)^2. it helps you by arranging shapes into a certain square and you arange a+b as it should be put to help you understand.
    e. i recommend this activity because if you understrand that material you can use its steps to help you maybe understand it better. or if you need an example of how to use it thats highly recommended as well.

2. a. The name of the activity is congruence theorems
    b. http://illuminations.nctm.org/ActivityDetail.aspx?ID=4
    c. math
    d. in this activity it is helping you understand the congruence of some triangles compared to others. it also is helping you understand what exactly conrunces theorems are.
    e. i recommend this activity  to kids because if you are taking geometry, which you learn both theorems and congruence of triangles, it can help you. i also recommend it because its and easy way to learn the subject.

3. a. Interactive Calculus Tool
    b. http://illuminations.nctm.org/ActivityDetail.aspx?ID=221
    c. math
    d. whe you type in what you want to do it will set up a graph. when you presh the button the graph forms and you see what you have created.
    e. i recommend this to kids that kids that have trouble with calculus. this can help you understand the criteria of what you are stumbling on.
