Students create reflections over two lines. In this reflections worksheet, students compare and contrast reflections over parallel and intersecting lines. They dilate figures and investigate the effect of the dilation using measurement...

Students complete worksheets involving rotational symmetry. For this geometry lesson, students complete worksheets to identify rotational symmetry and rotations. They compare and contrast rotated figures. Students examine the...

Learners investigate the different properties of trigonometry. In this precalculus lesson, students find the six different identities of trigonometric ratios. They relate the ratios to that of a right triangle and apply it to real life...

Students construct two-column proofs. In this geometry lesson, students use deductive reasoning and geometric properties to justify given geometric statements. Students compare and contrast proofs.

Students explore the concept of paragraph proofs. In this paragraph proofs lesson, students make flow charts of the process of getting ready for school. Students convert the flow chart to a paragraph proof. Students use geometric...

Students explore similar figures. In this surface area and volume lesson, students identify the relationship between the surface area and volume of similar figures.

Learners use glue, toothpicks, cardboard, marshmallows and more to build a structure. In this building lesson plan, students budget money to get their materials and make their building in teams.

Students explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

Students demonstrate measurement and estimation skills. In small groups, they are given a measurement, predict what object in the classroom is equal to that specific measurement, and record their data in a table that includes the...

Students solve problems with complex numbers. In this algebra lesson, students factor complex numbers and simplify equations using DeMoivre's Theorem. They add, subtract, multiply and divide using negative roots.

Students solve word problems using the law of sines. In this precalculus lesson, students work in groups as they define vocabulary terms. They apply the formula of sine to answer and solve problems.

Middle schoolers examine numbers and try to find a pattern in their relationship. They write an algebraic expression for the nth term.

Students use the terms: ratio, proportion, and measurement in their description of the life of a person one inch tall.

Students explore unit rate and ratio and discuss the relationship.

Fourth graders discuss characteristics of polygons and organize and visualize those characteristics using Kidspiration. Students import pictures that demonstrate the characteristics and save their projects to be reviewed and graded by...

Young scholars copy a present day artifact onto graph paper. In groups, they decide the scale of the drawing and create the picture using specific graphing points. They are also given photographs in which there are no graphing points and...

Young scholars explore the concept of translations. In this translations lesson, students discuss similarities and differences between images and pre-images. Young scholars apply translations to coordinates of figures. Students use patty...
