# Singapore Math question re:test

## Recommended Posts

Where does SM teach this concept? This picture shows questions from placement test 5a. I can’t find a lesson about this in 5a...or any of the other books. Any ideas?

I don't think exponents is covered from what I remember about SM Standards edition. I didn't do 6A/6B, but exponents isn't covered in the table of contents. I think it shows up in the middle school books.

Which version of the placement tests are you doing? I see exponents is introduced in Dimensions 6A. I don't know to what extent they cover it. The third question does involve order of operations which is covered at the beginning of Dimensions 6A with exponents. Maybe they are trying to suss out if you are testing at too low a level if you can answer that question correctly.

Why wouldn’t exponents/powers of ten be covered? This is suppose to be the US edition placement test. Same one on SM page as well as Sonlight and MFW. Weird!

Exponents are touched on in 5a during the prime factorization section, quite early on.  It is a very light overview.  I did a lot of spin-off lessons because the into to exponents is too light, IMO.

(I'm using standards ed.)

I don’t know but when we started AOPS ds looked like he’d never seen them before!  We did a bit with prime factorisation but that’s all I remember

I know we covered exponents because it pops up in Beast Academy 4A. I really don't recall it in SM. We did both programs plus other math resources. I know we extensively did exponents in AOPS PA which in comparison to Jousting Armadillos was like a five course meal versus an appetizer.

@LAmom  Are the red circles supposed to be marked wrong? The c exponent problem is incorrect, but a is correct.

We're doing level 5 in Standards this year, and exponents are covered in 5A.
