In this geometry activity, students use a ruler and a protractor to measure the lengths of the line segments and size of the angles that make up a drawing of a Christmas tree.  The one page activity has one problem.  Answers...

In this geometry learning exercise, students examine the height of 4 trees. They tell which tree is the tallest, make comparisons in 2 questions. They look at a picture of a pen, and a blue strip which they compare to the given units of...

In this angle measurement worksheet, students complete 4 multiple choice problems, determining whether given angles measure 90, 180, 270 or 360 degrees. A reference web site is given for additional activities.

Sixth graders study measurement problems. In this geometry lesson, 6th graders discuss the different types of measurement used in sports and answer questions regarding measurement problems in sports.

It doesn't matter whether secant lines intersect inside or outside the circle, right? Scholars extend concepts from the previous lesson to investigate angles created by secant lines that intersect at a point exterior to the circle....

Medians, midsegments, altitudes, oh my! Pupils study the properties of the median of a triangle, initially examining a proof utilizing midsegments to determine the length ratio of a median. They then use the information to find missing...

Geometry could be called the study of figures. An overview of the figures found in a typical geometry course contains a study of different triangles, quadrilaterals, and regular polygons. 

Young scientists study light reflection and refraction as they determine the critical angle, the rainbow angle, and color separation in rainbows. Teams record the data they collect in a shared spreadsheet and discuss results with the class.

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

Have you ever wondered how circles and angles relate to each other? Read a passage about right angles, acute angles, and obtuse angles, and answer reading comprehension questions about the information you learn. 

What does it take to show two triangles are similar? The 11th segment in a series of 16 introduces the AA Criterion for Similarity. A discussion provides an informal proof of the theorem. Exercises and problems require scholars to apply...

Geometric volume calculations are brought into the real world in a quick set of application problems. Learners are asked to help a patient figure out how to drink a prescribed amount of water both at work and at home. This activity...

Can you use triangles to create a circle? Learners develop the unit circle using right triangle trigonometry. They then use the unit circle to evaluate common sine and cosine values.

Fresh off the press, these math newsletters will challenge the problem solving skills of your young mathematicians. With an incredibly wide variety of questions covering the topics of arithmetic and geometry, these unique...

Building blocks have more uses than simply entertaining children. Young mathematicians calculate the volume of a given cube, and then calculate the volume and surface area of a prism formed from multiple cubes.

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

Bring math and reading informational text together with a reading comprehension lesson. After kids read about isosceles, scalene, and equilateral triangles, they answer five comprehension questions to demonstrate how they can use context...

Where can you see an aurora in North America? After completing an astronomy activity, scholars can locate the exact coordinates. Pupils plot points of the inner and outer ring of the auroral oval and answer questions based on...

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

It's all Greek to me. Scholars work a task that Greeks first formulated for an ancient math challenge. Provided with an angle and a point inside the angle, scholars develop conjectures about what is true about the shortest line segment...

Help the local elementary school fix their playground by calculating the amount of sand needed near the swing set. The problem practices setting up proportions and ratios with three different options for solving. You can chose the option...

Your geometry learners explore Angle-Side-Angle congruence in this collaborative task. The sum of the interior angles of all triangles being one hundred eighty degrees, is the key learners will discover as they explain their reasoning...

The phonemic awareness activities in this packet are designed to help kids develop skills in rhyming, syllabication, blending onsets and rimes, and beginning and ending sounds. Well worth a place in your curriculum library.
