Student scientists investigate triangle structures. In this building lesson plan, learners explore how to design triangle braces in the construction of structures in order to build a stronger base.

Students demonstrate how to solve word problems. In this problem solving lesson, students use strategies such as drawing pictures, using counters, and making a table to justify how they solved the word problem.

Students practice addition facts, record data, and construct a bar graph. In this probability lesson, students participate in a board game in which bicycles move towards a finish line based on players completing addition problems. Dice...

Students find the mean, median and mode. In hs statistics instructional activity, students collect, plot and analyze data. The identify the effect the central tendency have on the data and line.

Students investigate the concept of rising air in the formation of clouds and precipitation. In this rising air lesson, students conduct an experiment with hot and cold water that shows how warm water rises due to thermal buoyancy. They...

Fourth graders use square tiles to help them explain the concept of square numbers.

Third graders multiply one and two digit problems, identify place value, and maneuver manipulatives to solve problems.

Students use physical models and graphs in order to solve problems that have their origin in the real world that require algebraic thinking. The words are changed into equations and inequalities in order to be solved. This requires...

Second graders identify and describe basic geometric solids. Working as a class, 2nd graders describe geometric solids using the proper vocabulary and counting faces, bases, corners, and edges. In pairs, students use a computer drawing...

Pupils conduct an experiment to determine dew point and use a formula to detemine altitude. They construct a chart and predict what altitude clouds would form, given the dew point on the ground.
