Mathematicians show their understanding of a division problem. If a student can apply long division to a pair of numbers and determine a quotient, what other factors and multiples become apparent? The example illustrates a simple...

This is an opportunity for young mathematicians to apply reasoning to solve real-world problems with ratios. Even though there are three candidates for class president, students will only consider two at a time, making the first problem...

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

What better way to learn about fractions than with a couple pizzas? Help Jessica figure out how much of the pizza she has eaten, while teaching your class that fractions refer to a specific whole amount. This problem will be challenging...

Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your...

Identifying patterns is a crucial skill for all mathematicians, young and old. Explore the multiplication table with your class, using patterns and symmetry to teach about square numbers, prime numbers, and the commutative and identity...

Visual models are a great tool for demonstrating the concept of equivalent fractions. Given two pictures, young mathematicians first identify each fraction and then write an explanation for why they are equivalent. Use as a guided...

If a candy bar costs 3/4 of a dollar, can your mathematicians figure out the cost in cents? After watching this animated video, your learners will see that every fraction can be a decimal and every decimal can be a fraction. The video...

Sometimes the easiest way to understand division is to look at it as multiplication. Show your mathematicians that every problem can be written backward to make it easier for them. The video explains how the relationship between...

Roll the dice with this activity and teach young mathematicians about probability. Record outcomes for rolling two number cubes in order to determine what is most likely to happen. Graph the data and investigate patterns in the results,...

The distributive property is a foundational skill taught two ways in this interactive web page. Your young mathematicians can practice their order of operations by solving distributive problems working from inside out. They then move on...

Finding a fraction of a number is just multiplication in disguise. Young mathematicians can interact with this lesson to practice using multiplication to find a percent of a whole number. The narrator goes over how to put the number over...

With so many toppings to chose from, make the ice cream truck combinations a fun math problem that teaches your learners about outcomes. The video introduces a tree diagram that allows your mathematicians to see how to create...

See if your mathematicians can go from miles to yards to feet and back again with unit conversions. This video introduces the topic of the customary units of length and common equivalents. The main rule is to multiply when making...

Looking at large numbers can intimidate many young mathematicians. Use Zoe's place value machine to help learners understand the meaning behind each digit in a whole number. After learning about the ones, tens, and hundreds places,...

Zoe is reading books over vacation and wants to know at her current rate, how many will she finish by the end. Building on prior knowledge of fractions and ratios, young mathematicians learn how equivalent rates are used to answer her...

Going from fraction to decimal and decimal to fraction shouldn't be a chore, but an easy step for young mathematicians to do within problems. This interactive lesson shows how long division can change any fraction to a decimal. Started...

Cupcakes and pancakes help teach young mathematicians about multiples in this mouth-watering presentation. Watch and learn how knowing her multiples helps Zoe bake enough desserts for her birthday party. Following the presentation, go...

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...

Deepen the number sense of young mathematicians by exploring the process of prime factorization. Follow along with this step-by-step presentation that explains how factor trees are used to break a composite number down into its prime...

Learning division is a challenge for many young mathematicians, but this presentation on divisibility rules can make it much easier. Seven different rules are clearly explained and modeled with the support of multiple examples. Consider...

Here is a great poster to hang in your classroom to help remind your young mathematicians of the definitions of proper, improper, and mixed fractions. 

Engage young mathematicians in learning about fractions with this cross-curricular math and music lesson plan. After listening to and repeating different beat patterns, children realize that musical notes are just another way of...
