Practice the techniques associated with number theory. This 5-page worksheet has many different types of problems for the students to solve and is a great component for any number theory unit8.
Learners explore the concept of number theory. They discuss an assortment of number theory topics such as prime numbers, composite numbers, GCF, modular arithmetic, and others in a lecture style discussion. Pupils view videos about these topics as well.
This math review PowerPoint engages fifth grade students in an interactive review of math concepts. This review game includes questions on numeration, data interpretation and number theory. This is in a "Jeopardy" style format.
In this word search worksheet, students locate words related to number theory. The word list includes composite number, definite, and factors.
In this math crossword, learners use a set of clues and 15 words about number theory and fractions to complete a crossword puzzle. A reference web site is given for additional activities.
For this fractions vocabulary worksheet, students match a set of 15 number theory and fraction vocabulary words with their definitions. Answers are included on page 2.
In this number theory and fractions learning exercise, students search for words representing number theory and fractions in a word search. Students search for 15 words.
In this number theory worksheet, students complete a total of 13 problems, finding multiples, LCM and solving 1 word problem. 
High schoolers explore the concept of probability and number theory. For this probability and number theory lesson, students play an on-line game where they roll two dice and move that many spaces. High schoolers make tables of the number of ways a students can get a particular outcome. High schoolers use trees to organize their data.
In this complex numbers worksheet, students simplify, plot, iterate, and state bounded or bounded for complex numbers in nine problems.  The solutions are provided.
In this mental math worksheet, students complete 6 different sections in which they use mental math to solve problems. The first 3 sections consist of 45 subtraction, division and addition problems. The next 3 sections consist of 28 number theory and number challenge relays. There are 74 questions on this page.
Students secure information online using cryptography. In this algebra lesson, students use RSA technology to encrypt information on the internet. They use modular reduction of natural numbers to understand prime number theory.
In this number theory instructional activity, students solve and complete 14 different problems that are related to number theory. First, they determine if a number to a particular power is the same as stating the two numbers times each other and why. Then, students determine a number squared and then cubed. They also determine the power of a number raised.
in this number theory learning exercise, students use the Sieve of Eratosthenes to find all primes up to the number 100. Students follow the directions to circle primes and multiples on the hundred chart.
In this number theory learning exercise, students complete a set of 22 problems covering GCD, LCM and prime factorization. Students then play a "family fun" game based on LCM. 
Students participate in a chain link game to improve their math skills with factors, multiples, primes, and composites. In this math game lesson, students review the math concepts for the game by writing definitions for the topics. Students then play the chain links game.
Students will use number theory skills to investigate when certain planets are aligned. Students review the order of the planets from the sun and use this data to create a human solar system. They are assigned the name of a planet, and physically demonstr
In this math worksheet, students explore properties of the number line, both standard and imaginary. This thorough worksheet has many problems for the students to solve, and includes an answer sheet.
Learners review the order of the planets from the sun and use the data to create a human solar system. Pupils are assigned the name of a planet, and physically demonstrate the orbits and the time it takes for each of the planets to revolve around the sun.
