Our teacher told us the formula had one-third, but why? Using manipulatives, classmates try to explain the volume formula for a pyramid. After constructing a cube with six congruent pyramids, pupils use scaling principles from...

The matrix — it's not just a movie. The instructional activity introduces the concept of 2 x 2 matrix multiplication as a way to represent linear transformations. Class members determine when a linear transformation represented as...

Practice multiplication and division with a worksheet about multiplication properties. After reviewing the commutative property, identity property, zero property, and associative property, kids solve ten multiplication and division...

It's time for scholars to show what they know about coordinate planes with a collection of three assessments. The exams' objectives include plotting points on a single grid, measuring using the distance formula, and identifying...

Using a similar process from the first lesson in the series of finding area approximations, a measurement resource develops the proof of the area of a circle. The problem set contains a derivation of the proof of the circumference...

Scholars model the height of water in a container with an exponential function and apply average rates of change to this function. The main attraction of the lesson is the discovery of Euler's number. 

Trying to find a linear transformation is like finding a needle in a haystack. The second lesson in the series of 32 continues to explore the concept of linearity started in the first lesson. The class explores trigonometric, rational,...

Help the class visualize operations with complex numbers with a lesson that formally introduces complex numbers and reviews the visualization of complex numbers on the complex plane. The fifth installment of a 32-part series reviews...

To work through the complexity of coordinate geometry pupils make the connection between the coordinate plane and the complex plane as they plot complex numbers in the 11th part of a series of 32. Making the connection between the two...

The second lesson on finding inverse matrices asks class members to look for a pattern in the inverse matrix and test it to see if it works for all matrices. The teacher leads a discussion to refine the process in finding inverses,...

Use a triangle area formula that works when the height is unknown. The eighth installment in a 16-part series on trigonometry revisits the trigonometric triangle area formula that previously was shown to work with the acute triangles....

You can never have enough cookies, but do you have enough ingredients? This activity allows your bakers to discover how many batches of cookies they can make with the ingredients provided. Also useable as an independent assignment, your...

We are used to finding the area of a circle by plugging the radius into an equation. Here, learners are required to go further to find multiple areas and calculate the difference. They must detect a pattern in order to figure out the...

Develop young mathematicians' ability to compare fractions with investigation into the number 1/2. After brainstorming a list of fractions equivalent to 1/2, children identify a pattern in the numerators and...

Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the...

Mo' money, mo' problems! But don't worry, here is an assessment that proves to young mathematicians that they can solve actual money problems. The resource includes 11 money problems involving addition, subtraction, multiplication,...

Reinforce the concept of factors, multiples, and prime numbers with a 16-problem practice activity. Eight pages offer a variety of problem solving opportunities with clear objectives and tips for successful completion. 

Add, subtract, multiply, and divide fractions with a worksheet designed to give your learners practice performing fraction operations. 

Reinforce the concept of place value with an eight-page practice exercise equipped with 18 problems for scholars to show what they know.    

Eight independent worksheet pages challenge scholars to solve 12 problems that focus on negative numbers in the context of temperature in degrees of celsius. 

Reinforce estimation and the four operations—addition, subtraction, multiplication, and division—with eight page, 15 problem independent practice exercise.

Raise the bar and strive to be above average. The assessment task requires budding mathematicians to think critically and evaluate given statements. What does it truly mean to be above average?  

Connect science, math, and art for a true interdisciplinary lesson plan! Learners explore simple machines in art. Through analysis with a physics app, they identify positions of kinetic and potential energy and make conclusions about work.

You'd be surprised what you can do with a string! The constraint is the length of string, and the task is to maximize area. Given a series of composite shapes, learners must create a formula for the maximum area for a specified...
