Complex solutions are not always simple to find. In the fourth activity of the unit, the class extends their understanding of complex numbers in order to solve and check the solutions to a rational equation presented in the first...

This grid features 15 animals, and scholars use a coordinate system to describe the location of each. The x-axis is labelled with letters and the y-axis with numbers, and they list the coordinate pairs beside the animal names below the...

Four is the perfect number—if you're talking about parallelograms. Scholars determine a possible fourth vertex of a parallelogram in the coordinate plane given the coordinates of three vertices. They read a conversation...

The 10th lesson in a series of 32, continues with the geometry of arithmetic of complex numbers focusing on multiplication. Class members find the effects of multiplying a complex number by a real number, an imaginary number, and another...

Use inverse trigonometric functions to work with ramps, rabbits, and Talladega. The class models real-world situations with trigonometric functions and solves them using inverses in the 15th installment of a 16-part series. Pupils solve...

Use a function to operate on two variables. Pupils look at operating with complex numbers as a function of two variables. The interactive squares the input and adds a constant to it. Learners visualize the resulting output and its...

Does complex number multiplication have the class spinning? Here's a resource that helps pupils explore and discover the geometric effect of multiplying complex numbers. In the 14th installment in the 32-part unit groups look at the unit...

Class members perform complex operations on a plane in the 17th segment in the 32-part series. Learners first verify that multiplication by the reciprocal does the same geometrically as it does algebraically. The class then circles back...

Develop a model for prep. The resource provides examples of how items reflect modeling and data analysis for Smarter Balanced assessments. Items use on-grade or below-grade content to focus on the modeling aspect. The questions revolve...

In this slope of a line activity, students solve and graph 2 different problems that include determining the slope of a line using the equation y=mx+b. First, they define the slope of a line and the y-intercept. Then, students use the...

Can your kindergartners identify which group of pictures has one fewer? Given three groups of pictures (kites, planes, and butterflies), youngsters count the amount of items and check the box for the group that has one fewer. A great way...

Keep track of your sixth graders' mastery of the Common Core math standards with this practice assessment. Taking a different approach than most standardized tests, this resource includes not only multiple choice questions, but also...

In this line of best fit instructional activity, students solve and complete 8 different problems that include plotting and creating their own lines of best fit on a graph. First, they study the samples at the top and plot the ordered...

Offering a comprehensive overview of the beginning of World War II, this resource could be a useful addition to a unit on this topic. It could be used as a way to lead a discussion on the war, or as a review tool before a test. Either...

Graphing can be festive! This Easter worksheet has scholars using coordinates to record the location of ten holiday images. The first is done for them, and the grid is large and appealing to younger learners. Consider visualizing this...

As you introduce graphs and coordinate pairs, use this guided activity to get scholars started. They reference an example before recording number pairs to identify the location of 12 letters on a grid. Next, learners examine shapes on a...

Challenge the class to prove that the dilation properties always hold. The lesson develops an informal proof of the properties of dilations through a discussion. Two of the proofs are verified with each class member performing the...

Students plot the migration paths of birds using latitude and longitude data from a table.

Get your learners up and moving, all while reviewing numbers on the number line! For this activity, learners are grouped in teams outdoors. The teacher will have already created number lines on the ground (with chalk, tape, etc.), and...

Students explore how the angle and distance of an object can change it's temperature. After reviewing how the position of the Earth affects the temperature of the planet, student groups design and perform an experiment to test how...

Middle and high schoolers use the Pythagorean Theorem to complete a table showing with the magnetic field strengths in given cities. They find the average value of the Earth's magnetic field and plot one of the three-dimensional values...

In this money activity, students fill up a grid with coins and then roll dice to get ordered pairs and take the money of the ordered pair that they roll. Students then add up their money in the end and see who wins.

For beginning point plotters, these graphs give a good introduction. They examine a graph with shapes drawn onto it and each vertex labeled. There are 20 total, and scholars write the coordinates of each labeled point. All of these are...

First graders watch a video about the seasons. They role play with the teacher the sun and earth. The student's heads are the earth, their foreheads are the Northern Hemisphere. The teacher shines a flashlight on them to simulate the sun...
