Who knew the sum of a number's digits gives such interesting information? The 18th installment of a 21-part module has scholars investigate division by three and nine. After looking at several examples, they develop divisibility tests...

Three, two, one...liftoff! Elevate math skills to new heights while having a blast. A great resource that combines entertainment and education for children of all ages.

In this mathematics activity, 4th graders fill in the chart with the factors divisible by each number. Then they study the charts and respond to the five word problems that follow. Students also find as many common factors of the given...

Twenty-eight flashcards make up a set designed to reinforce math vocabulary. Two styles of cards showcase either a bold-faced word or a corresponding definition card equipped with an example and labels. Terms include commutative property...

Scholars learn how to write number theory proofs by viewing a video reviewing techniques for proofs on divisibility, parity, and consecutive integers. They then write proofs for a handful of conjectures on a worksheet.

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Patterns in math emerge from seemingly random places. Learners explore the patterns for factoring the sum and differences of perfect roots. Analyzing these patterns helps young mathematicians develop the polynomial identities.

How many birthdays do leap year babies have in a lifetime? Learners explore the question among others in a lesson focused on different calendar systems. Given explanations of the Julian, Gregorian, and Martian calendars, individuals use...

Your fifth graders will appreciate the simple, direct explanations, examples, and practice exercises in this well-organized unit on fractions. Beginning with an introduction to fractions, the packet flows smoothly through the fraction...

In this math worksheet, 3rd graders focus on determining missing factors. Students complete 34 problems representing factors of whole numbers.

How can you tell if fractions have equal value? Use various collaborative activities to demonstrate the ways to determine whether or not fractions are equivalent.

This task investigates divisibility properties for the numbers 3, 6, and 7. Aligns with 4.OA.C.

This lesson shows examples of how to get started with the prime factorization of three-digit or larger numbers, using a factor tree. includes numerous practice exercises.
