Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...

Students sort gummy bears, count gummy bears, and evaluate and record their favorite colors of gummy bears.

Isn't paper pushing supposed to be boring? Learners attempt a paper-pushing puzzle to develop ideas about angles inscribed on a diameter of a circle. Learners then formalize Thales' theorem and use geometric properties to develop a proof...

Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Help learners translate word problems into algebraic equations. They will rewrite words using symbols and evaluate algebraic expressions using real life scenarios, animation sequences, video presentations, and activities to help students...

Students sort and compare apples before making apple prints. For this apple lesson, students use a painting to inspire art prints made with apple halves. Students compare and sort apples.

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this lesson. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is by viewing a...

An engaging hands-on activity is presented. Learners of all ages are addressed in thie unique plan. K-5 learners identify, name, and define a rectangle, square, triangle, and the concept of area. Older learners prove the Pythagorean...

Here is an excellent cross-curricular lesson. Learners relate multiplication to area by making a grid on graph paper, and then creating the same grid in real space outside in the school yard.

Establish and study the parts of a map with your class and, then they will work in small groups to create their own detailed map, including a legend.  There are specific instructions to follow on what needs to be included.

Human graphs, anyone? Did you eat fruit today? What is your favorite costume? Have your K – 6 learners graph the responses. Early elementary grades may count and compare while upper grades compare responses of different groups or make...

Deepen the fractional number sense of young learners with this introductory lesson on equivalent fractions. After completing a short warm-up activity, children go on to work in pairs using fraction circles to complete a table of...

Here is a fine lesson on inequalities of fractions for your third graders. After a modeling session by the teacher, pupils are put into groups and are led through a discovery session using fraction bars and inequalities. The lesson...

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...

Students measure the actual size and distance of the solar system using scale and ratio. They watch and discuss a video, create a distance-scale solar system model, and compare the scale sizes of planets to their actual sizes.

Read the story, The Very Hungry Caterpillar, and complete activities from multiple subjects. Make a mural, create a class graph, discuss the life cycle of a butterfly, research information about butterflies on the Internet and make...

Young mathematicians explore number values by utilizing food as a visual aide. They discuss the differences between halves, fourths, and eighths and how they are visually represented by a pizza. Then create their own pizza in class and...

As a cross-curricular instructional activity, your class examines the issues of gender discrimination, careers, and gender roles. They read and discuss an article, prepare a proof of the Pythagorean theorem as a class, and develop a...

Students explore weather instruments. In this weather lesson, students make rain gauges, anemometers, and barometers following the instructions given in the lesson. Students set up a weather station using their instruments and record and...

A complex question looking for the total cost of a stained glass window by calculating area and circumference of a circle. With detailed components, this activity will challenge your designers to figure out if they have enough money to...

Shapes are everywhere in the world around us, from rectangular doors to the circular wheels of a car. The second lesson in this series opens the eyes of young mathematicians to this wonderful world of shapes as they search the classroom,...

Your middle schoolers will show what they know with their bodies when they become the coordinate plane in this conceptual development unit. Starting with the characteristics of the coordinate plane, learners develop their skills by...

The key is ... After a day of instruction on key features of graphs, groups create a poster and presentation on the key features of their given function graph. The resource provides an extension activity of "telephone" using...

Let your use of the resource be in proportion to its usefulness. Pupils investigate similar triangles by measuring side lengths and considering given angle measures. The results of the investigation help develop generalizations about...
