This product can be used in a classroom or as a mini take-home project! Students will use a compass and straightedge to make art out of parallel lines, congruent angles, perpendicular bisectors, and angle bisectors. Rubric is included!

This lesson teaches students that in planar geometry, the sum of the measures of the interior angles of a triangle is always 180 degrees. The lesson starts with an exploratory exercise on GeoGebra, looking at the angle measures of a triangle. (This can easily be replicated on paper with pencil and protractor, if necessary). Then, the teacher will guide the students in a formal proof using parallel lines that is simplified to the middle school level. After that, students will be guided in an

This lesson follows the 5E method of lesson planning. It infuses the history of Euclid and the Elements throughout to provide context for the lesson. 1. Engage (5 minutes):Explain a brief history of Euclid, Elements, and geometric constructionsState learning objective and corresponding common core standard 2. Explore (5 minutes):Paper folding activity: Lead students through a paper folding activity that creates a perpendicular bisector, without telling them what they are creating. Gui

This crossword puzzle is a fun way for teachers to assess their students' understanding of essential triangle congruence vocabulary. This assessment comes with an answer key and a list of the vocabulary terms with precise and accurate definitions.

I created this resource based off of the Massachusetts state standards for mathematics by grade level. This is a perfect tool to assess what your students know when coming into 5th grade. There are problems about identifying 2-dimensional figures and their lines of symmetry, telling time on an analog clock, knowing US currency, adding, subtracting, multiplying, and dividing two and three digit numbers by hand, adding fractions, finding the GCF and LCM of two numbers, identifying coordinate pai

This product is a quick guided worksheet that explains what radians are in terms of arc length and radius, using the more general example of the circumference formula.
