In math this week we learned lots of new vocabulary words. Examples of these vocabulary are prime numbers, which only have 2 different numbers that divide  into them, composite numbers, which have more then two factors. We also learned how to make a factor tree and a division table. The other two things we did where GCFs, or greatest common factor which is the biggest number that divides evenly into both numbers, and the LCM or least common multiple, which is the smallest multiple of the given numbers.
