Watch this and see if you can spot what drives me up the wall.
Do you think she will remember how to find the area of a triangle? Do you think this is really tutoring? How about telling her WHY the area of a triangle is 1/2 bh? HMMM??? This is how I explain to my kids:
How do we find the area of a square? Base times height, right (we already went over how to do this and why it works)? Please draw a line from one corner to the other corner of the square. What shapes do you see? 2 Triangles!!! So, the area of one of those triangles will be 1/2 of what the area of the square was, right? Right. If they are confused about other types of triangles have them take 2 of the triangles and cut one in half and arrange it on either side of the whole triangle to make a rectangle. Still it is 1/2 the area of the rectangle. Now they will remember. If I just tell them the formulas, how will they learn? How will they figure out how to explore problems on their own? Hmmmm? I hate that commercial.
