Indiana just published a new math reference sheet. I do not know which part of this sheet bothers me the most.
1) The odd mix of volumes of solids, with inconsistent use of "B", for the area of the base. But wait, look at the formula for a cone, here the area of the base is spelled out. I think this takes away from the general understanding of how we can go about finding the volume of a solid. Maybe it is just me.
2) Just the abc's of Pythagorean Theorem. We need more here, it falls short of the story it tells about all triangles.
3) What are those = signs doing with those conversions!! The only one that is correct is 1inch=2.54cm. Precision indeed!!
I am all for leveling the mathematical playing field by giving students the formulas on SAT, ACT, ISTEP, ECA exam....But what Indiana is giving the students is ambiguous, not true, and vague.
Here it is.
