Right angles, acute angles, obtuse angles, central angles, inscribed angles: how many types of angles are there? Learners first investigate definitions of inscribed angles, central angles, and intercepted arcs. The majority of the...

Serve up angle measurements on paper plates. Pupils use paper plates and paper-folding techniques to create a unit circle with conversions for special angles. Using their plates, learners explore the relationship between angle...

Breaking the rules is one thing, proving it is another! Learners expand on their previous understanding of congruence and apply a mathematical definition to transformations. They perform and identify a sequence of transformations and use...

It's time to get crafty with shapes! Your future farmers demonstrate their geometric ability by building a farm using triangles, circles, rectangles, and squares. But first, scholars take part in a brainstorm session inspired by their...

Young mathematicians extend their knowledge of rational numbers on a number line to graph inequalities by first using number cards to compare rational numbers. They finish by using similar reasoning to graph inequalities on a number line.

Develop a definition of irrational numbers through an exploration of square roots. The 11th activity in this series of 25 asks scholars to estimate the value of a square root. Learners observe as the estimation extends further and...

Students identify how to use a scatterplot to compare two sets of data to determine if they are related. Then they identify and describe the definition of regression line (the "line of best fit"). Students also identify how scientists...

Fourth graders work with patterns while using large numbers. In this patterning lesson, 4th graders go over the definitions of the words: predict, estimate, attendance, increase, and decrease. They complete worksheets in which they track...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Not all pie graphs are about pies. The class conducts a survey on favorite fast food categories in a lesson on data representation. Pupils use the results to create a circle graph.

Sprechen sie Deutsch? Future cryptographers must decide whether an unknown text is written in English or in German. They use provided pie charts about the frequency of words in the English and German languages to help make their decisions.

Young mathematicians look for patterns in inverse functions as they relate to the original functions. The comprehensive instructional activity emphasizes vocabulary throughout as well as algebraic and graphical characteristics of the...

How hard can it be to split something in half? Learners investigate how previously learned concepts from angle bisectors can be used to develop ways to construct perpendicular bisectors. The resource also covers constructing a...

Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.

First graders discuss the definition of patterns, and sing the song, Going Buggy, identifying patterns in the song. They create original patterns using bug counters and insect stickers.

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Sixth graders inspect M&M's to complete statistical data. Students interpret percent of colors represented. They convert data from decimals, fractions, and percents. Using the data, 6th graders create a bar graph and a circle graph.

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Young scholars gain an appreciation of the polygons and polyhedrons around them that make their world one of order and strength. They build polygons and polyhedrons, and then construct airplanes out of polygons.

Students identify and construct figures that tessellate. They investigate which regular polygons tessellate and how to modify them to make other tessellating figures. Students explore how naturally occurring tessellations have been...

First graders define and identify integers, rational, irrational, real, and complex numbers. They place number cards in ascending and descending order.

Middle schoolers explore how a pattern built with square tiles grows and describe the change from stage to stage. They predict later stages of a tile design sequence and create math equations related to the growth of tile designs.

Students discuss square numbers. In this math lesson, students find square numbers and support their answers. Students find sums and products that are square numbers.

Young scholars explore how to identify the range, median, and mode in a list of numbers by using concrete materials.
