Interesting...DD8 lacks confidence in math, too. Her school also uses Everyday Math. She is a high math achiever (MAP 99%, high math grades), but per CogAT, quantitative reasoning is a "relative" weakness" (high verbal and nonverbal, lower Q score). Her school differentiates in math, but does not offer AP Math until 4th grade (she has always been placed in the highest math group, so she seems on track). She has been claiming to hate math since 2nd grade (but seems to actually be somewhat good at it?), but loves science. I have noticed some silly, what appear to be careless, mistakes on math assignments lately. I have been trying to keep her confidence in math up - but it is a struggle. Interested to hear what others have to say...
