This learning resource titled "Number Block Factory: Building Prime Bricks" aims to teach students how to decompose composite numbers into their prime factors using factor trees and express the results with exponents. The lesson includes a detailed procedure for building factor trees, identifies prime numbers (referred to as 'Prime Bricks'), and emphasizes counting and representing these factors using exponent notation. Students will complete a factorization example of 72, fill in factor trees, and engage in independent activities such as constructing factor trees for 100 and decomposing either 80 or 96. The success criteria for students include breaking numbers into factor pairs, identifying prime numbers, and rewriting prime factors using exponents, ensuring a comprehensive understanding of prime factorization.
