Communication is the key. A presentation provides 25 sample items for Claim 3, Communicating Reasoning, for the Smarter Balanced High School Math assessment. Items require pupils to answer the question and provide logical reasoning to...

Whether determining orbitals of space craft or designing experiments with conductive dough, many young scientists discover physics is phun and attempt the AP exam to get college credit. Use the free response questions from the 2018...

How do dilated line segments relate? Lead the class in an activity to determine the relationship between line segments and their dilated images. In the fourth section in a unit of 16, pupils discover the dilated line...

Given a pair of parallel lines and a triangle in between, geometers prove that the sum of the interior angles is 180 degrees. This quick quest can be used as a pop quiz or exit ticket for your geometry class.

True-false and multiple-choice questions are posed in Part A of this exam, covering the topic of electromagnetic radiation. In Part B, problems relating to refraction must be solved. This is a well-rounded exam that will help you...

Let your physics learners take this electromagnetic radiation exam home to show what they know. You could also use it in class or assign it as a review. The content covers concepts pertaining to color, wavelength, frequency,...

Challenge the class with inscribed circles in triangles. The assessment task requests class members use their knowledge of circles and right triangles to prove two triangles are congruent. They go on to utilize their knowledge of...

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...

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...

Determine whether two triangles are similar. The lesson presents opportunities for pupils to find the criterion needed to show that two triangles are similar. Scholars use the definition of similarity to find any missing side...

If both pairs of opposite sides of a quadrilateral are congruent, is the quadrilateral a parallelogram? This task asks learners to determine the answer and to support their answer with a proof. The resource includes a commentary for...

This task asks learners to prove that the segment joining the midpoints of two sides of a parallelogram is both congruent and parallel to an adjacent side of the parallelogram. The activity would be good to use in a discussion about how...

Students are challenged to identify and measure angles created by parallel lines and a transversal as well as complementary and supplementary pairs.

Test yourself on the topics of identifying the characteristics of a longitudinal or transverse wave such as the wavelength, crest, and areas of compression with this multiple choice quiz.

This site is a page that students can check their understanding of parallel lines and transversals. The page contains small hints to the solution of each problem, students can check their answers online. After checking their answers they...

In this practice activity, students calculate angles created when two parallel lines are intersected by a transversal. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.
