Multiplication & Division Mission
Build multiplicative thinking — arrays, area models, equal groups, partial quotients, factors, multiples, and prime numbers.
8 activities · Work through in order for a complete lesson arc
Multiplication Arrays & Equal Groups Builder
Explore multiplication with arrays, equal groups, skip counting, and fact families. Visual models for times tables from 1×1 to 12×12
Start with arrays and equal groups as concrete models.
Area Model Multiplication Studio
Multiply 2-digit and 3-digit numbers by drawing area models. Break each number into tens and ones, compute partial products in each rectangle, and add them up to find the total.
Multiplicative Comparison Builder
Build and interpret 'times as many' comparisons using animated bar models. Find the product, base, or multiplier in multiplicative comparison word problems.
Division as Sharing & Grouping Explorer
Explore division through equal sharing and equal grouping models with visual animations, remainder highlighting, and inverse multiplication connections
Partial Quotients & Remainders Explorer
Divide step by step using partial quotients. Subtract friendly multiples, stack the quotients, and find remainders. Practice with word problems that ask what to do with the leftover.
Factors & Multiples Playground
Find all factor pairs of a number and see them as rectangular arrays. Explore multiples, identify prime and composite numbers, and discover GCF and LCM with a Venn diagram.
Prime & Composite Detective
Determine whether numbers are prime or composite by building all possible rectangular arrays. Sort numbers into Prime and Composite bins and discover that 1 is neither.
Capstone — identify primes and explore factor trees.
Factor Tree & GCF/LCM Calculator
Build visual factor trees, find prime factorizations, and compute GCF and LCM with a Venn diagram of shared prime factors.
