Multiplication facts worksheets
Times-table drills: one table, a range of tables, squares or anchor facts, in order or shuffled.
Factor trees and prime factorization
Finish each factor tree, then write the number as a product of primes.
About this worksheet
Each factor tree is drawn with the branches already in place. Students write the prime number in each empty circle, then write the prime factorization at the bottom, smallest prime first.
Every number is split into factors in a way that always ends with the same primes, so the answer is the same however the tree is drawn. Pick how big the numbers get, from 30 up to 500.
