Fourth grade math requires students to have mastered all single-digit addition (through 9+9) and subtraction (through 18-9) facts .  Students should understand the concept of multiplication, and know multiplication facts through 10x10.  Students should be familiar with the concept of division.   Although we will work to improve speed and accuracy with all facts, students MUST practice their facts at home regularly.  Students are expected to correctly complete 30 facts in one minute.
