This set includes a total of 20 pages - 16 pages with 10 problems on each page (5 multiplication/5 division) and 4 pages of answer keys. The multiplication begins with 2-digits times 1-digit and progresses to 3-digits times 2-digits. Division problems progress - with and without remainders. The division problems have 1-digit divisors. Hopefully repeated practice will help the students master their multiplication and division skills. Multiplication CCS 4.NBT.5 and Division CCS 4.NBT.6. Hope this is helpful. Thank you! Have a great year!
