When one method isn't enough to teach GCF, try two! This interactive webpage introduces factors and the prime factor tree to find the greatest common factor of two numbers. After the lesson, have learners click to try the two examples...

Find the common denominator between prime factors, factor trees, and the distributive property. Scholars learn to find the least common multiple and greatest common factor of pairs of numbers. They rotate through stations to connect...

This is an exercise in finding the greatest common factor of two whole numbers. Use in direct instruction or as part of your guided practice. Make up additional problems for home work. It also can be used as a mini-assessment or test...

Incorporate riddles into your math lesson by having students make tree factors and determine if the number is a prime or composite. They will also use other clues to find the answer to the riddle while sharpening their...

Make math simple with this step-by-step presentation on fractions in their simplest form. Multiple approaches are introduced including, most efficiently, the division of numerators and denominators by their greatest common factor. Work...

Submarine sandwiches not only taste good, they also make for great math models. Follow along as Zoe explains how to calculate equivalent fractions, while cutting up a sandwich for herself and her friend. She demonstrates the process...

RJ instructs your sixth graders in two different methods of determining least common multiples. The first is by listing several multiples of each number, and the second is by drawing factor trees. This is an ideal flipped classroom...

Are you looking for review questions before standardized testing? Grade 6 Claim 1 Item Slide Show offers nine questions covering a variety of topics using decimals, factors, and multiples. With separate slides for answers, using the...

Individuals learn to apply the Euclidean algorithm to find the greatest common factor of two numbers. Additionally, the lesson connects greatest common factor to the largest square that can be drawn in a rectangle.

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,...

Polynomial multiplication and factoring go hand in hand. Why not teach them together. This resource begins with an area model for distributing a monomial and then connects the process to factoring the GCF. Learners then advance to...

Young mathematicians discover trees organize more than just families — they help factor, too. The lesson begins with factor trees and develops slowly to factoring by grouping and special patterns. 

Young mathematicians graph polynomials using the factored form. As they apply all positive leading coefficients, pupils demonstrate the relationship between the factors and the zeros of the graph.

Is it bigger, or is it smaller—or maybe it's the same size? Individuals learn to describe enlargements and reductions and quantify the result. Lesson five in the series connects the creation of a dilated image to the result. Pupils...

Prime or composite, that is the question. Teach your class how to find the answer with this step-by-step presentation that defines and provides examples of each type of number. When addressing larger numbers, divisibility rules are...

The product of the hard work is learning. Scholars use a simulation tool to collect information to analyze. They must decide when two ships traveling back and forth across a river at different rates will meet on the same side. The intent...

This fourth of twelve units in a series continues the investigation of functions through equations and inequalities. However, the modular nature of the lessons in the section make this an excellent resource for any curriculum...

Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

Build upon linear functions to learn about quadratics. The lesson introduces the concept of zeros for quadratic functions and makes the connection to the linear factors of the function. It presents quadratics in both graphical and...

How do you graph a quadratic function efficiently? Explore graphing quadratic functions by writing in intercept form with a activity that makes a strong connection to the symmetry of the graph and its key features before individuals...

Hello Algebra! If you're in need of a resource with a books worth of examples and practice problems, this is it. Some topics include linear equations, polynomials and exponents, rational expressions, quadratic equations, and a...

Does it matter how many points to dilate? The resource presents problems of dilating curved figures. Class members find out that not only do they need to dilate several points but the points need to be distributed about the entire curve...

How do dilated line segments relate? Lead the class in an activity to determine the relationship between line segments and their dilated images. In the fourth section in a unit of 16, pupils discover the dilated line...

Class members come up with a hypothesis on the number of decimal digits in the product of two decimals. Learners work in groups to complete several decimal multiplication problems. The results help groups develop a conjecture on the...
