As part of first quarter work, we are in process of checking accuracy on addition and subtraction facts. You would be helping your child if you spent some time helping them brush on the these basic facts. If addition and subtraction facts seem to be solid, they might consider working on multiplication and division facts (that will be included in second quarter work). They need to know answers without taking time to count on fingers. They are checked with timed test. Fifth hour is doing multiplication first quarter.
