Description

Factors and multiples can be a confusing challenge! When your students solve these fun math mystery enrichment riddles for factors and multiples within 100 in math centers or for independent practice, they'll build critical thinking skills and math skills, too!

These math riddles are a unique way to keep the fun in math while growing your students' abilities in multiplication, division, and critical thinking skills.

Here's how these math mystery riddles work!

Choosing from four numbers on each card, your students will determine Super Sleuth's Secret Number by using math clues to eliminate three of the options. With each riddle task card they complete, your students will determine factors and/or multiples for four numbers.
