In this cross-curricular sampler of worksheets, students determine the meaning of specialized vocabulary and to understand the precise meaning of grade-level-appropriate words, describe and connect the essential ideas, arguments, and...

Older elementary students will appreciate how clearly Sal explains how to find the prime factorization of 75. He shows the complete process, taking note of numbers that are, and are not primes, and why.

By offering a step-by-step explanation of how to identify prime numbers, this presentation would be a terrific way to give learners a visual example of prime numbers. This is a simple, and easy way, for students to understand the "why"...

Here it is ... a video that shows the prime way to learn about prime factorization. Scholars watch an instructional video that shows how to find the prime factorization of a number. The method shown in the video is prime factorization...

The only factor to consider in determining prime numbers is the factors of the number. Young mathematicians learn to identify prime numbers. They see that a prime number is any number with only one and itself as its factors.

Nine true or false, multiple-choice, and discussion questions make up an interactive designed to reinforce scholars' knowledge of prime and composite numbers. A number chart reveals every prime number through 100. 

Give the class a prime example of using prime numbers. After reviewing prime factorization of numbers with the video, pupils use their knowledge to determine greatest common factors and least common multiples in the worksheet. The...

How many prime numbers are there between 1 and 100? By using a prime time resource, your scholars should be able to answer this question. Using arrays, they determine if numbers are prime or composite, and then write a prime...

Factors of any other color are not mine. Pairs play a game identifying proper factors of chosen numbers. Pupils develop a strategy for playing the game and when they can choose a prime number.

Riddles are a great way to encourage learners to develop their logical thinking skills, and the fish riddle offers the perfect challenge. Viewers must determine how to rescue a series of tanks containing an endangered species of fish.

Number patterns can seem mysterious. Help your learners unravel these mysteries as they complete an intriguing task. Through examination, collaborative groups determine that they are able to produce all integers above a certain value by...

It seems the post office has run out of stamps! Learners build all the values of postage available if the post office only sells five- and seven-cent stamps. The task provides an opportunity to create an expression in two variables and...

Is math real? Scholars first learn about the Goldbach conjecture and prime numbers as an introduction to the philosophical idea of whether numbers actually exist. The video continues on to use an example of a circle to consider math from...
