Young scholars examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Young scholars experiment with the area and perimeter of polygons. Students...

Learners study parallel and perpendicular lines. In this parallel and perpendicular instructional activity, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.

Students manipulate a variety of materials and computer applets in order to explore area and the units used to measure it.

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

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...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Fifth graders explore polygons. In this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

In this math worksheet, students solve six problems about 3D objects. Students also solve six problems about measuring 3D objects.

Learners use their hands, feet, computer, and rulers to measure the perimeter of objects. In this measurement lesson plan, students measure objects around the room and computer generated shapes.

Students create, transform, and critique their own piece of artwork. In doing this lesson, students get more experience working with angles, lines, and measurement. They gain experience seeing, and creating their own patterns and shapes.

Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

Students watch a segment of the PBS video which show the lemurs' ability to jump. In pairs, students collect measurement data involving each other's length of a standard step, a standing broad jump, and a long jump. They record their...

Young scholars explore the relationship between how big a side of a triangle is and how big its opposite angle is by creating triangles using an interactive website.

In this images worksheet, students use different sized mirrors to determine how many angles and images are reflected. Students complete 5 sets of directions.

In this polygon worksheet, students draw various polygons according to given specifications and find angle sums. A website reference for additional resources is given.

Students work with thermometers to complete problems about temperature. They investigate cooling patterns, how location affects temperature, and what happens when water having different temperature is mixed. They measure temperature in...

In thins triangles review worksheet, students examine 3 triangles and their measurements. Students classify them as acute, right, obtuse, equilateral, isosceles, or scalene.

In this similar-congruent worksheet, students determine measures of unknown angles, draw congruent shapes and determine whether shapes are congruent. A reference web site is given for additional activities.

Students examine physics by completing a bicycle experiment in class. In this gravity instructional activity, students measure the characteristics of different bicycles and compare their different race times. Students utilize a...

In this rotational symmetry worksheet, 5th graders determine if the two figures have rotational symmetry. This worksheet explains and provides examples of rotational symmetry.

Students explore the concepts of length, perimeter and area. Students develop an understanding of length, perimeter, and area. Students calculate the area and perimeter of random shapes and calculate the area and perimeter of a triangle...

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...
