Square roots and triangles

*We practiced finding the lengths of the sides of right triangles using the Pythagorean theorem which is equal to c^2 = a^2 + b^2 .
*This allowed us to also calculate the square roots of numbers by hand. Diego hadn't done
this is a while either so he had to learn it again as well.
*We also learned the word of the week. It was 'burgeon', which we'll define next week.
*Last week's word of the week was 'ameliorate' which means to make better (Jose remembered this correctly after a week!).
