What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

Introduce learners to two methods to estimate the formula for the area of a circle. The first method uses a sector of a circle to form a rectangle, and the other uses grids to estimate the area. The problems in the 18th segment of a...

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...

Perimeter check! Pairs work on finding the areas of semicircles and quarter circles using a relationship with squares. The problems challenge pupils to find areas of composite figures made from rectangles, semicircles, and quarter circles.

Uncover strategies for finding areas of composite figures. The 23rd lesson in a 29-part module has young mathematicians decompose figures to find total area. Figures decompose to rectangles and circular regions.

What if I can no longer justify area by counting squares? Lead a class discussion to find the area of a rectangular region with irrational side lengths. The class continues on with the idea of lower approximations and...

Calculate the areas of scale drawings until a more efficient method emerges. Pupils find the relationship between the scale factor of a scale drawing and the scale of the areas. They determine the scale of the areas is the square of the...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Scholars determine distances on the coordinate plane to find areas. The instructional activity begins with a proof of the formula for the area of a parallelogram using the coordinate plane. Pupils use the coordinate plane to determine...

The 21st segment in a 28-part series provides learners with area problems involving composite figures. To find the solution, pupils must decide whether to add or subtract areas. The composite figures are composed of quadrilaterals,...

Pack the instructional activity into your plans. Young mathematicians learn about packing and optimization with the context of circular paving stones. They use coins to model the paving stones, and then apply knowledge of circles and...

Learners can enjoy pi with pie! A collection of short activities celebrates pi day with a word search, a maze, and real-world problemsn. Using pi in formulas for area, circumference, and volume as well as exploring simple fractions is...

Students investigate the circulatory system. In this circulatory system lesson, students complete a WebQuest and explore all the areas of the heart. Students determine the functions of different parts of the circulatory system and...

A resource that makes for excellent group work as students explore the area and perimeter of different complex designs made up of squares and circles. The commentary gives a clear definition of perimeter, but suggests that group members...

Small groups create skits that illustrate the different perspectives of those involved in the transitioning of Santa Rose island from private ownership to National Park.

There's a lot of thought that goes into setting up safe and supportive classroom environments. From establishing a whole group meeting area and arranging desks, to organizing classroom supplies and creating bulletin board displays,...

Dr. Martin Luther King, Jr.'s "Letter from Birmingham Jail" serves as an exemplar for a mini-lesson on semicolons. Working alone or in small groups, class members first circle all the semicolons in the letter, and then consider how this...

The interactions between the Coureurs de bois (runners of the woods) and the First Nation Peoples as they engaged in the fur trade are the focus on this Canadian history exercise. Kids select learning centers based on their learning...

Learners explain why some species of plants and animals occur in more than one area. They watch as the teacher puts an overlapping circles on the chalkboard, students are asked to predict what kinds of things they would expect to find in...

Whether you're planning to set up your classroom for the start of another school year or just need a change of scenery, this sample chapter taken from a Responsive Classroom book provides suggestions for making the most...

Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...

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...

Citizenship and basic human rights are the focus of the instructional activity presented here. In it, learners compile a basic list of human rights, then access a website in order to complete some activities that are based on rights and...

Life is not always fair. Who's heard that before? This same concept moves to a larger scale using prejudice and bias. Pupils discuss where prejudice attitudes derive and how they develop throughout life. Reading comprehension...
